764 MR. OLDFIELD THOMAS ON [Nov. 13, 



Shark's Bay, a locality interesting for many reasons, and the 

 specimens obtained there are included in an appendix to the 

 present paper. 



The series of specimens amounts to about 400, a number 

 indicative of a vast amount of energy and hard work on the part 

 of Mr. Shortridge and of the friend who accompanied him, 

 Mr. John W. Bell. 



Mr. Shortridge's field-notes on the species occupy the greater 

 part of the present paper, and are of much value as putting on 

 record the status of each animal at the present time. Every 

 species obtained in either the first or second collection is men- 

 tioned, as the field-notes 'apply to both ; but the record of the 

 specimens sent only refers to the second collection, a list of the 

 first having been already published. 



One novelty only from the mainland now needs description, a 

 Rat allied to Mtis lineolatits of Eastern Australia. Two of the 

 Bernier Island specimens also require new names. 



It may be noted that before Mr. Shortridge's expedition only 

 two Bats, Nyctophilns timoriensis and Vespertilio ^^uinihcs , were 

 recognised as occurring in "Western Australia. This number is 

 now raised to ten by the capture there of Pipistrellus tasmaniensis, 

 Chalinolohus gouldi and morio, and NycUno'imis australis and 

 jjlaniceps, by the discovery of Pipistrellus reguhis and Scoteinus 

 balstoni, and by the recognition of yi/ctophiltis geoffroyi as a 

 valid species.
