XXXVII. — Description of anew Species of Satyrid Butterfly 

 from Costa Rica. By H. Gkose Smith, B.A., F.E.S., 

 F.Z.S., &c. 



Oxeoschistus cothonides. 



Male. — Upperside. Anterior wings resemble 0. cothon, 

 Salvin. Posterior wings, discal area briglit tawny, with a 

 broad marginal border of dark brown, irregularly indented by 

 the tawny area between the veins ; a dark brown spot centred 

 by a white dot situate in the tawny area between the two 

 lowest median nervules, and two similar contiguous spots 

 above the anal angle, as in 0. cothon. The discal area be- 

 comes darker tawny brown towards the base and inner margin, 

 the darker area extending transversely from the middle of the 

 costa and crossing the cell a little beyond its middle towards 

 the anal angle, where it merges in the dark brown marginal 

 border. The female resembles the male. 



The underside does not differ appreciably from 0. cothon. 



Hah. Cartago, Costa Rica. 



Expanse of wings 2^ inches. 



Described from one male and two female specimens. At 

 first I thought this insect might be the female of 0. cothon ; 

 but there being both sexes in the collection, and possessing a 

 female of 0. cothon which does not differ from the male, I 

 conclude that the very distinct colouring of the upperside of 

 the posterior wings justifies me in describing it as distinct 

 from 0. cothon. The specimens were sent by Mr. Under- 

 wood with a good series of 0. cothon from the same locality. 



XXXVIII. — On Mammals from Celebes, Borneo, and the 

 Philippines recently received at the British Museum. By 

 Oldfield Thomas. 



The specimens referred to in the present paper were mostly 

 collected by Messrs. Charles and Ernest Hose in N. Celebes 

 and by Mr. Alfred Everett at the extreme south of the same 

 island, and both at about the same date, October to 

 December 1895. One of the chief objects of these naturalists 

 was to obtain for our National Museum specimens of the 

 numerous small mammals that have been described of late 

 years from the island of Celebes and have hitherto been 

 unrepresented in the British Museum. This object has
