 Aphiloscia „ Budde-Lund (5), p. 291 ; Taf. 16, fig. 15—31, 1908. 



Seychelles Archipelago : Mahe, mountain forest, Cascade, one large specimen, 

 9"5 mm. long, 4'o mm. broad. Farquhar, 30 Sept. 1905, several small specimens. 



This species seems to be common in Madagascar and in the Comoro Islands ; it is 

 also found in Mauritius and Reunion. 



Subfamilia Olibrininae. 



Antennae longissimte, flagello longo, multiarticulato (10 — 15). 



Maxillpe prioris paris lamina exterior longa, angusta, margine posteriore nudo, apice 

 dentibus c. duodecim, omnibus integris, simul appendice longa, mobili ; lamina interior 

 apice dense crinito penicillis duobus minus manifesto discretis instructa. 



Maxillae alterius paris lamina angusta indivisa, apice integro, dense crinito. 



Maxillipedum articulus labialis angustus, margine exteriore et interiore ad apicem 

 pilis longis instructo ; palpus magnus, latus, 2-articulatus, articulus 1 brevis spinis solitis 

 duabus minutis instructus, articulus 2 permagnus, latus, margine interiore ad apicem 

 undulate producto cum margine exteriore crinibus longis instructo ; mala palpo multo 

 brevior, ad apicem angustata. 



Exopoditum pleopodum trachea destitutum. 



Olibrinus nov. gen. 



Having rather hurriedly to give a report of the collection of terrestrial Isopods from 

 the Malayan Peninsula gathered by the Skeat Expedition, I had no opportunity to make 

 a profound examination of the few specimens of the below-mentioned species ; on account 

 of its habitus and the multi-articulated fiagellum of the antennae I placed the species in 

 the genus Trichoniscus. I now have had a somewhat larger number of specimens for 

 examination, and, as it seems, of three different though very nearly allied species. 

 Olibrinus has to be placed in the family Oniscoidce, even though not only by the antennae 

 but also by the structure of the trophi it makes a transition to the family LigiidcB. I 

 have, however, considered it necessary to distinguish it as a subfamily. 



36. Olibrinus antennatus (Plate 22, figs. 24 — 26). 



Trichoniscus antennatus Budde-Lund in Proc. Zool. Soc, London, 1902, p. 379. 

 Superficies Isevis, nitlda. 

 Oculi minores ; ocelli 8 — 10. 



Antennae perlongae, gracillimse, corpus longitudine paulum superantes ; scapi articulus 

 1 brevis ; articuli 2 et 3 breviores, subsequales ; articulus 4 fere duplo longior quam
