1. Nyctophilus timoriensis Geoff. 



5 (Bat b). King River, King George's Sound. Near sea-level. 

 190, 191. Southern Cross. 1160'. 

 Forearms 44-45 mm. 



2. Nyctophilus geoffroyi Leach. 



c?. 166. Jaurcli Hills, near Kalgurli. 1250'. 



c?. 175. $.176,189. Laverton. 1650'. 



These specimens are of much interest, for they conclusively 

 prove the correctness of Mr. Tomes's assertion that the small 

 JV. geoffroyi of Leach, with a forearm of about 35-36 mm., is a 

 different species from JSf. tiinoriensis. Tomes's specimen No. 1, 

 from Albany, King George's Sound, recently acquired with his 

 collection by the British Museum, may be treated as typical of 

 Leach's species, whose type was without locality. 



Mr. Shortridge's specimens agree very well with this Albany 

 individual in proportions, but are rather browner in colour. 



3. Yespertilio pumilus Gray. 



S (Bat a). 2 & 3. King River, King George's Sound. Near 

 sea-level. February. 



d. 139, 141, 142, 143. Parker's Range, Southern Cross. 

 1163'. 9-17 August. 



d. 161, 164. $. 140, 148, 162, 163, 167. Jaurdi Hills, 

 Kalgurli. 1250'. 21 Sept.-5 Oct.

Noctulina tas'nianensis Gray, List Mamm. B. M. p. 194 (1843) 

 {sine descr.). 



Vespertilio tasmaniensis Gould, Mamm. Austr. iii. pi. xlviii. 

 (1858). 



Vesjjerugo kreffiii Peters, MB. Ak. Berl. 1869, p. 404; Dobson, 

 Cat. Chii'. B. M. p. 232 (1878). 



2 (Bat c 1). King River, King George's Sound, 26 February, 

 1905. Near sea-level. 



This is a very rare bat, no previous specimen having reached the 

 Museum since the original type referred to by Gray and Gould. 

 Another example, from Tasmania, is in the Tomes collection.

 A medium-sized species of the group with minute outer incisors. 

 Size rather larger than in P. kuhli. Fur rather long and 

 shaggy (hairs of back slightly over 5 mm. in length), extending

 near the sides of the body. General colour above dark Prout's
