| The area investigated comprises a 5 miles broad E-W belt mainly through the group of rocks called ”Complejo Antiguo” by professor Parga-Pondal (1956). The section runs roughly from the village of Lage on the west coast eastwards towards Carballo. The object was to detect the various relationships between the rocks of this group; more especially it is an attempt to elucidate the metamorphic history of this so-called Ancient complex in terms of a scheme of syn-, late- and post-kinematic metamorphic events. |

| 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... |

| The present paper contains descriptions of several new species of the genus Bactra Stephens from the tropics of the Old and New World, while stray notes and noteworthy records on known species are added. Records on Australian species are excluded, pending an opportunity for a revision of the entire Bactra fauna of that continent — with the exception of two species which are recorded in order to rectify some synonymies. In total one allied genus, ten species, three subspecies and one forma are described as new, while records on 42 already known species are presented. Since the genital characters of Bactra species are of such paramount importance it was deemed necessary to present elaborate figures of the genitalia of the two sexes, besides the usual... |

| The writer ascertains the existence of a fairly large number of Old World Gomphidae exhibiting a mixture of admittedly epigomphine and gomphine characters; he emphasizes the point that certain features hitherto considered of primary importance can no longer be used as a basis for subfamily grouping. Examples are given of intermediate genera whose proper allocation cannot even be estimated, for which reason the segregation of the Epigomphinae is considered ill-founded and must be suspended. |

| Only part of the very extensive entomological collections made in New Guinea during various expeditions by Dutch scientists has so far been studied, but this already yielded many new species. A first superficial survey of the Orthoptera in these collections provided a number of specimens of a species of Phyllophora, which proved distinct from any of the forms described before. As I believe the species to be new to science, it is described here as Phyllophora boschmai nov. spec., and named in honour of Professor Dr. H. Boschma, who for many years was my teacher and director at the Rijksmuseum van Natuurlijke Historie, and to whom I owe many thanks for his practical advices during my studies. The greater part of the specimens mentioned here have been... |

| Potamogeton trichoides Cham. & Schld. gold tot voor kort als een der zeldzaamste fonteinkruidsoorten van ons land. In zijn bewerking van de Nederlandse Potamogetons in Ned. Kruidk. Arch. 46, 1936 geeft KLOOS als bekende vindplaatsen op: Ooy bij Nijmegen, Zwijndrecht, Tilburg en Valkenswaard. In de laatste jaren zijn er echter geleidelijk aan meer vondsten voor de dag gekomen, zodat CLASON in zijn manuscript voor de binnenkort te verschijnen aflevering van de Flora Neerlandica reeds vermeldt, dat het aantal bekende groeiplaatsen tot ca. 25 is toegenomen. Hij geeft op, dat de soort zeldzaam voorkomt op verspreide vindplaatsen, voornamelijk in het Haf-, het Fluviatiele- en het Kempense district, maar waarschijnlijk op vele plaatsen over het hoofd is... |

| This paper gives a survey of the forms of Scorpiurus muricatus L. In contradistinction to Thellung who distinguished in his “Flore adventice de Montpellier” 4 subspecies, the present authors subdivide the species into 2 subspecies, each with some varieties. They can be identified with the aid of the following key. In using this key, one must be aware of the fact that several transitions between the subspecies and the varieties exist. 1. Calyx-teeth triangular, shorter than to about as long as the tube. Pod loosely coiled, almost in one plane. Ribs of pod all smooth or only the outer ones muricate or spiny; spines stout, at most as long as the diameter of the pod. Seeds mostly slightly curved subsp. muricatus 2. Ribs of pod all smooth ........... var.... |

| In a previous paper (Van Laar, 1961) the female genitalia of the species of Depressaria Hw. s.l. occurring in the Netherlands have been dealt with. In the present paper the male genitalia of these species will be treated. Although Hannemann (1953, 1954, 1958) already described the male genitalia of the species of Depressaria occurring in Europe, it was thought to be worth while to give here a survey of the male genitalia of the Dutch species, supplementing that of the female genitalia, in order to help students to discriminate between these rather uniform species. In view of the complexity of these structures the most efficient way seemed to present elaborate illustrations and abbreviate the descriptions. In the present work the classification used in the... |

| Single female specimens of dragon flies are often difficult to identify owing to the fact that, when they are known at all, the descriptions are incomplete and mostly lack the essential figure of the genitalia. The following are descriptions of the unknown females of five species, the males of which have been known for the last eighteen to fifty years. They are all complete with figures of the genitalia. The material from which the descriptions have been made has been accumulated during many years of collecting. I am indebted to Mr. J. BELLE, Paramaribo, who was kind enough to place at my disposal, for description, some of the unknown females collected by himself. |

| During the summers of 1962 and 1963 the Geologisch en Mineralogisch Instituut of Leiden University and the Rijksmuseum van Natuurlijke Historie at Leiden carried out a joint exploration of the geology, oceanography and biology of Ria de Arosa, a fiord-like bay in northwestern Spain, north of Vigo. These investigations were not confined to the Ria proper, but also included the affluent rivers like the Rio Ulla and Rio Umia. These explorations will be continued in 1964. In July 1963 a specimen of a peculiar isopod was found by the oceanographic party when exploring the Rio Ulla, a river emptying in the northeastern corner of the Ria de Arosa. This find caused the biologists to give more attention to the locality where the animal was caught and many more... |

| Some new localities of Scirpus rufus (Huds.) Schrad., Trifolium micranthum Viv., and Juncus inflexus L. in the southwestern part of Friesland. Naschrift van de redactie. Tijdens het voor de druk gereed maken van bovenstaand artikel ontvingen wij van de heer Van der Ploeg enige exemplaren van Trifolium micranthum Viv., die hij aantrof in het herbarium van een van zijn leerlingen, S. Muizelaar, en die verzameld waren op de oostelijke helft van het Oudemirdumer Klif. Deze nieuwe vindplaats vormt dus een schakel tussen die bij Vollenhove en de hier boven beschreven vondst op de dijk van Workum naar Hindelopen. Verder is het vermeldenswaard dat T. micranthum ook op Ameland blijkt voor te komen. Het was wederom de heer Van der Ploeg die de soort daar in augustus... |

| The genus Cerceris Latreille contains several hundreds of species and is represented in all zoological regions, in temperate areas as well as in the tropics and subtropics. In 1942 Arnold stated that about 650 specific names had been proposed in this genus; since then another 125 new species have been described. The species of certain parts of the world are well known. In recent years De Beaumont (1950, 1951, 1958) and others have published some important revisions of the species of Europe and North Africa, while Tsuneki (1961) studied the species of North Eastern Asia (for further references see pp. 19-21 of Tsuneki's paper). The Ethiopian Cerceris have been monographed by Brauns (1926) and by Arnold (1931, 1942). The species of the Nearctic region have... |

| The genus Batracomorphus was erected by Lewis in 1836 to contain B. irroratus, then a new species from near London. Lewis published a very detailed description of his new genus, and compared it with Iassus Germar (= Allygus atomarius F.) or Phrynomorphus Curtis (= Euscelis lineolatus Brullé); then he writes: "but the position of the antennae, ocelli, &c. evidently allies it to Bythoscopus, Germ." (= Iassus lanio F.), "from which its depressed form will at once distinguish it". The name was emendated by Agassiz to Batrachomorphus. After Lewis many authors, who were not able to see "at once" the difference, united Batrachomorphus with the genus in which they placed Iassus lanio F. Ribaut gives a more detailed account of the characters separating the two... |
