| The present study deals with systematic and taxonomic problems in the acrostichoid fern genus Bolbitis (Lomariopsidaceae). The idea came from Prof. Holttum, Kew, in view of his intended revision of the lomariopsidoid ferns for Flora Malesiana. Originally the study was confined to the Asian representatives. However, various problems remained unsolved after the study of these taxa alone, and it was decided to monograph the genus. The taxonomy of the genus Bolbitis was seriously misunderstood in the past—parallel evolution obscuring true relationships—and a rather intricate synonymy has resulted. A brief historical sketch of its taxonomic adventures is worked out. The gross-morphological criteria used for the discrimination of the species by Copeland (who... |

| An interesting brachiopod fauna from Namurian (Marsdenian?) deposits — provisionally named the Meré beds herein — is described. The fauna contains seven new species: Drahanorhynchus cantabricus, Anopliopsis? parva, Caenanoplia martinezi, Tornquistia scutiformis, Aseptella asturica, Kitakamithyris merensis, and Plicotorynifer lamellosus; and one new genus: Aseptella with the type species A. asturica. The material of a new productellid and a new ambocoeliid was too poor to give them formal names. The special character of this fauna — only a much older fauna from the Chappel Limestone of Texas (U.S.A.) being closely comparable — indicates special environmental conditions: presumably a soft, muddy bottom. The brachiopod fauna indicates a Namurian, probably... |

| A primitive freshwater planarian, Eviella hynesae gen. et sp. nov. is described from Australia. It is characterized by its lack of eyes and pigment, possession of caudally branched oviducts, and fully fused testes. Although a primary bursa is absent, its function being taken over by the modified female genital canal, the female copulatory system is posterior to the male system. Despite this maricolan feature, and other similarities with primitive southern hemisphere freshwater planarians that have been classified in the Maricola, the present species is placed in the family Dugesiidae of the Paludicola. Evidence from its sensory organs suggests that it belongs on the main evolutionary line from which the majority of Australasian freshwater planarians have... |

| Progress in classification of Chelicerata has been thwarted especially by two factors, viz., the concept of mites as one monophyletic group, and the opinion that this group consists of species with a highly modified plan of construction and without any trace of true segmentation. The only characters which are generally shared by all groups of mites refer to the presence of a gnathosoma (i.e. the cone-shaped, movable structure comprizing the mouthparts), and the occurrence of a larva with only three pairs of legs (the last-mentioned character is also found in Ricinulei). A comparative morphological study of the gnathosoma (Van der Hammen, 1970b, 1972) has, however, demonstrated that two fundamentally different types can be distinguished, which must be the... |

| The junior author has collected in Surinam at night on a dead log, a few specimens of a very interesting new aradid species representing a new genus in the subfamily Carventinae, which we propose to name Apterocoris surinamensis. All measurements were taken with a micrometer eyepiece, 25 units = 1 mm. Apterocoris Kormilev et Van Doesburg, new genus Ovate, more tapering anteriorly; first three antennal segments, femora, tibiae and lateral borders of the body, with erect, stiff bristles; entire body, with exception of apical half of antennal segment IV, labium and tarsi, covered with red brown incrustation. Apterous. Head longer than width across eyes; anterior process deeply cleft anteriorly, not reaching basal 1/4 of antennal segment I. Antenniferous... |

| INTRODUCTION Ligur uveae is generally considered an anchialine species (found in land-locked, generally supralittoral saltwater pools) with the type locality given simply as "Uvea, Loyalty Islands" by Borradaile (1899). The species is widely distributed geographically, although locally evidently confined to a very restricted habitat. Its known range extends from the western Indian Ocean to Polynesia: Aldabra, western Indian Ocean (Borradaile, 1917; Gordon, 1936); Halmahera, northern Moluccas, Indonesia (Holthuis, 1947; 1963); Uvea, Loyalty Islands (Borradaile, 1899; Gordon, 1936); Sayawa Islet near Uvea (Monod, 1968); Vatulele Island, Fiji Archipelago (Gordon, 1936; Derrick, 1957; Marden, 1958; Reed & Hames, 1967); Vanua Vatu and Vanua Levu Islands,... |

| Eleutherodactylus gutturalis nov. spec., belonging to the E. fitzingeri group and characterised by a black to grey throat with a median white stripe, a shagreened dorsum with larger tubercles interspersed, absence of digital webbing, relatively long legs, and uniformly coloured concealed parts of the thighs, is described from Surinam, French Guiana and Brazil. |

| Until recently the mycoflora of the West Frisian Islands has been rather neglected. In the last few years, however, members of both the Rijksherbarium and the Netherlands’ Mycological Society (N.M.V.) have been collecting more frequently on these islands. The results of their fieldtrips are promising for the future as many interesting and rare fungi have been found. In a previous paper (Noordeloos, 1975) I described a rare species of the genus Marasmiellus Murr., viz. M. caespitosus (Pat.) Sing. from the Island of Texel¹. I now want to introduce, from the same island, another member of the same genus. |

| During soil fauna investigations performed in 1959 by Dr. J. van der Drift (see his study, 1963), three specimens were collected of a small coleopteroid heteropteron, representing a new species belonging to the genus Thaumamannia Drake & Davis, 1960. Up till now, only one other species in this genus was known, viz., T. manni, collected in an ants' nest by Mr. W. H. Mann in Bolivia. The other three known species in the subfamily Vianaidinae1) belong to the genus Anommatocoris China, 1945, and are also found with ants (Drake & Ruhoff, 1965). The new species described here is closely related to the Bolivian species, and in all likelihood is also myrmecophilous. It is the first record of a vianaidine tingid for Surinam and for the Guyana's. The... |

| In 1893, Gestro founded the genus Ceroplophana, only including the simultaneously described species C. modiglianii Gestro. He considered the genus — based on the only known specimen — closely related to Peperonota Westwood, Didrepanephorus Wood-Mason, and Dicaulocephalus Gestro. For rutelines, the males in these genera have strikingly developed secondary sexual characters. Gestro's species was the first representative from an insular locality of this South-East Asian group (Si Rambé, Batakland, North Sumatra; this locality is mentioned on the map in the report of the explorer who collected the material, Modigliani, 1891). Recently I could study seven ♂ of modiglianii from West Malaysia. They show striking differences from Gestro's description. Gestro's... |

| Past studies of the farm sector have concentrated on the use of farm based resources in the farm context alone. Changes in the economic environment have widened the opportunities available to these resources and have thus tended to make this narrow definition of the farm firm less relevant. Some recognition of this situation has emerged in more recent studies. The aim of this note is to collate and examine the degree to which farm labour resources are employed in off-farm activities in Australia. The main conclusion drawn from the evidence available is that, while in aggregate part-time farming is a fairly minor activity, in some sectors it is increasing in importance and constitutes a considerable outlet for farm based labour resources. |
