Ilab. Paramau, Mimika R., S. Dutch New Guinea. Low 

 country. 



Ti/pe. Adult female. Original number 2516. Collected

 Expedition to New Guinea; presented by the Subscribers. 



This distinct species is no doubt most nearly allied to 

 T. saccolaimus, but is readily recognizable by its smaller size, 

 different colour, shorter and broader skull, and by the detailed 

 cranial characters above described. I have named it in 

 honour of my colleague Mr. W. R. Ogilvie-Grant, by whom 

 the Expedition to New Guinea was initiated, and to whom 

 we owe the very acceptable collection of mammals obtained 

 by its members. 



The large Japa'aese Noctule. 



The large form of JSyctalus found in Japan was named 

 " Vesjjertilio molossus " by Temminck in the ' Fauna Japonica,' 

 but that name was antedated and invalidated by the earlier 

 Vespertilio molossus of Pallas (1767). 



In 1878 Dobson assigned the name lasiopterus to it, from 

 Schreber's plate Iviii. B, dating from 1781, and this identifi- 

 cation, unlikely as it seemed, might have had to be adopted 

 were it not that Fischer (1829) and AVagner (1810), with 

 equal rights as " revisers," placed the name as a synonym of 

 noctulu, asserting that it was an old individual. Dobson's 

 specimen, moreover, proves on examination to be not tiie 

 Japanese, but the large Italian form, to which the name 

 muximus has been applied. 



Whether Fischer and Wagner's assignation of lasiopterus 

 to noclula should be adopted, or whether any evidence con- 

 necting it definitely with maccimus may turn up, is for the 

 moment immaterial, although personally I believe it to have 

 been the latter animal. Indeed, Dobson's specimen, from 

 the Lidth de Jeude collection, and therefore probably in
