A new species of Pimelodid Catfish from eastern Brazil, Pimelodella boschmai nov. spec. Naturalis
Stigchil, J.W.B. van der.
In 1955, the late Dr. O. Schubart, Director of the Estaçao Esperimental de Biologia at Pirassununga (São Paulo, Brazil) kindly put at my disposal a small collection of fishes which he had assembled in the Mogi-Guassu (river) below the Cachoeira de Emas (Emas falls). Only a series of eight apparently conspecific specimens is discussed here. At first sight, the present specimens appear to closely resemble Pimelodella griffini Eigenmann, especially six examples with a prolonged first soft dorsal ray. However, excepting several minor differences, P. griffini has the dorsal spine prolonged instead of the first ray, while it has the adipose dorsal fin much shorter. Having only two specimens of P. griffini, moreover of dubious identity, available for comparison,...

A new species of Pseudobba (Mollusca Gastropoda) from western New Guinea Naturalis
Henrard, J.B..
Pseudobba boschmai nov. spec. Description. — The shell is large, very globose, umbilicate, and more or less irregularly obliquely ribbed; it is peculiarly striate-pitted between the ribs. The apex is obtuse. The whorls number 6 1/2, the upper are slightly convex, the following soon become more convex, while the ultimate whorl is very large, convex, and descending in front; the sutures are impressed. The upper whorls are dark fawn-coloured, gradually becoming darker; the body whorl is of a beautiful chestnut colour, becoming blackish towards the aperture, this colour is visible as a vertical band of about 1 cm broad; it does not obtect the reflexed peristome which is white and has a white lip. The aperture is dark and smooth. The peristome is nearly...

A new species of Spilomyia from Sicily (Diptera, Syrphidae) Naturalis
Lucas, J.A.W..
Spilomyia boschmai nov. spec. Female. — Length about 16 mm. The eyes are bare, brown, with a dark marginal area and a dark longitudinal band just behind the middle; furthermore a number of dark specks is present, especially in the anterior half. The face is bright yellow, without a dark median line; it is covered as far as the bases of the antennae with rather long, erect, yellow hairs. The frons is yellow with a black median stripe extending from the black vertex to the implantation of the antennae on the antennal tubercle; in the paratype, however, the base of the antennal tubercle is yellow, interrupted in the middle with black. The pubescence of the frons is shorter than that of the face and is of a black colour. The black median stripe broadens...

A new species of the Octocorallian genus Paragorgia trawled in Florida waters by R.V. "Gerda" Naturalis
Bayer, F.M..
The genus Paragorgia was established by Milne Edwards & Haime in 1857 to receive the large, boreal scleraxonian octocoral from the "Norwegian Ocean", called Alcyonium arboreum by Linnaeus (1758). In subsequent years, that species was reported also from localities in the northern Pacific Ocean (Kinoshita, 1913; Hickson, 1915) and from high southern latitudes off the Falkland Islands (Broch, 1957). In 1883, Koren & Danielssen described two new species from Batalden, Norway, Paragorgia nodosa and Briareum frielei, which generally have been treated as synonyms of P. arborea. Nutting (1908, 1912), however, reported P. nodosa from deep waters off Hawaii and Japan and, furthermore, established a new Japanese species, Paragorgia regalis. Kinoshita (1913)...

A note on Himalayan Buzzards, Buteo buteo (Aves) Naturalis
Voous, K.H.; Bijleveld, M.F.I.J..
VAURIE (1961) in a recent review of the geographical races of the Common, or Eurasian, Buzzard (Buteo buteo (Linnaeus)) has found no evidence in favour of the recognition of a West Chinese or Tibetan mountain race of that species. Even less he considers it likely that the Buzzard nests in mountain forests in the Himalayas. In his conclusion he is at variance with PORTENKO (1929 : 644) who described a special race from the Cham region in East Tibet and mentioned specimens ascribed to this race from West China, Darjeeling, Sikkim, and the northwestern Himalaya. This race, originally described as Buteo japonicus saturatus, was re-named by PORTENKO in 1935 Buteo japonicus refectus on nomenclatorial reasons (Orn. Monatsb., 43 : 152). It was considered by...

A note on the genus Liocranium Ogilby (Pisces, Scorpaenidae) Naturalis
Mees, G.F..
The genus Liocranium was established by Ogilby (1903) to contain a new species of scorpion-fish from the east coast of Queensland: L. praepositum. The genus remained monotypic until McCulloch (1921) placed Paracentropogan scorpio Ogilby in it, a species also described from the Queensland coast. Whitley (1933) did not agree, and transferred P. scorpio to a separate new genus Vadesuma. In the meantime Weber (1913) described as Paracentropogon pleurostigma and Paracentropogon cynocephalus two scorpion-fishes from the East Indies. These two species, however, were not well placed in Paracentropogon, and therefore De Beaufort (1949) created the genus Sibogapistus for them. Apart from McCulloch's (1921) remark that: "Paracentropogon cynocephalus Weber is perhaps...

A palynological study on the Tertiary and Upper Cretaceous of British Guiana Naturalis
Hammen, T. van der; Wymstra, T.A..
The pollen content of bore-hole samples and mine sections from the coast and from the bauxite belt of British Guiana has been studied. The pollen zonation is shown in fig. 6 and diagram IV. The description of the Upper Cretaceous and Tertiary pollen species is partly given in this article and partly in Van der Hammen, 1963; the Paleocene and Eocene species will be described in Leidelmeyer, 1965. The general picture obtained for the Guiana Basin, is summarized in three sections, one along the coast (fig. 18), one parallel to the Demerara River (fig. 24) and one parallel to the Berbice (fig. 25). The more detailed interpretation and correlation of the two deep coastal wells of Rose Hall and Shelter Belt is given in fig. 5. The situation in the bauxite areas...

A Pollenanalytical investigation of a boring made near a River Dune in South-Holland Naturalis
Voorrips, A..
In this investigation special attention was paid to phytosociological aspects. The period in which the layers were formed could be dated as extending from the beginning of the Atlanticum to the present day. Radio-carbon dating is necessary, however, in order to obtain more precise results. It is not excluded that transgressions have influenced the succession. More investigations are necessary to complete our image of the holocene development of this area.

A preliminary revision of the Indo-Pacific species of Ophioglossum (Ophioglossaceae) Naturalis
Wieffering, J.H..
The differences between the most recent complete treatment of this genus by Clausen (1938) and the present revision are, I think, of a rather fundamental nature. For, though Dr Clausen and myself agree that in the troublesome taxa, ‘the small number of characters .... has forced workers .... to base conclusions concerning species often on trivial details such as leaf cutting and size, characters which would not ordinarily be considered of fundamental importance in other groups’ (l.c. p. 5), from there on we have followed a different train of thought. Clausen stated (l.c. p. 6) that ‘If these characters were not adopted as criteria for species, it would be necessary to reduce the species to a very small number and thereby remove the opportunity to keep...

A revision of the Australian Owls (Strigidae and Tytonidae) Naturalis
Mees, G.F..
INTRODUCTION When in December 1960 the R.A.O.U. Checklist Committee was reorganised and the various tasks in hand were divided over its members, the owls were assigned to the author. While it was first thought that only the Boobook Owl, the systematics of which have been notoriously confused, would need thorough revision and that as regards the other species existing lists, for example Peters (1940), could be followed, it became soon apparent that it was impossible to make a satisfactory list without revision of all species. In this paper the four Australian species of Strigidae are fully revised, over their whole ranges, and the same has been done for Tyto tenebricosa. Of the other three Australian Tytonidae, however, only the Australian races have been...

A study of the Levantine and Pontic Harpacticoida (Crustacea, Copepoda) Naturalis
Dov Por, F..
INTRODUCTION Though both are parts of the Mediterranean basin, the eastern Mediterranean and the Black Sea form distinct units from both the hydrographic and the biological points of view. The Levantine basin — delimited by the Anatolian peninsula, the Syrio-Israelian shores and the Egyptian littoral — is the main basin of the eastern Mediterranean. We studied the Harpacticoida along the Israel coasts. Also we used the data of Brian (1927, 1928) from the Dodecanese, of Gurney (1927) from the Suez Canal zone, and of Steuer (1948) from Alexandria, in order to obtain a comprehensive survey of the levantine Harpacticoida. In the Black Sea we studied the Harpacticoida of the Rumanian shores and a few samples from the Bulgarian shores and from the pre-bosphoric...

Aanwinsten voor de Nederlandse adventief-flora, 6 Naturalis
Ooststroom, S.J. van; Reichgelt, Th.J..
Two acquisitions to the Netherlands adventitious flora from the year 1963. 1. Kochia scoparia subsp. densiflora (Turcz. ex Moq.) Aellen, distinguished from the typical subspecies by the long hairs at the base of the flowers, was found near Amsterdam as a grain introduction. 2. Tetragonolobus maritimus (L.) Roth. This species was found on the grassy slope of the Kunderberg near Voerendaal (prov. Limburg). It is supposed to be adventitious there, what is also said of the specimens from the nearest locality in Germany, the Schneeberg near Vaals, W. of Aachen. Polygonum compactum Hook. f. and Dicentra eximia (Ker) Torr., escaped from cultivation.
