5 I DESCRIPTIVE ACCOUNT OF

GENUS CHI R P D M Y S . 



CHIROPODOMYS PUSILLUS. 



Chiropodoinvs pusi/Iiis, Thomas, Ann. and Mag. Nat. Hi.st. 

 Ser. 6., vol xi. p. 345, 1893. 



Size smaller than in Ch. i^/i'roulcs. Ears and teet decidedly 

 smaller and tail shorter than in that species. Fur crisp, close 

 and velvety. General cok)ur tawny fawn, head and centre of 

 back darker, sides paler, outer sides of arms and legs like back, 

 but the wrists and ankles greyish, a colour which also extends 

 upon the metatarsus ; fingers and toes white ; under surface 

 from chin to anus pure white ; no darker markings on face ; 

 ears small, evenly oval, practically naked. Tail but little longer 

 than the head and body combined, uniformly brown above and 

 below, its terminal tuft of hairs of about the same thickness, 

 but less extended and commencing more abruptly than in the 

 allied species. 



Skull smaller and rather more delicately built than in the 

 other species and showing even more markedly the roundness, 

 simulating immaturity, characteristic of the genus ; supraorbital 

 bead but slightly developed ; anterior palatine foramina very 

 short. Molars small, their structure as usual. 



Measurements of the type (skin) : — 



Head and body 76 millim. ; tail Mi ; hind foot ly^ ; heel 

 to front of last foot-pad 7'2 ; ear from notch 11 '5. 



Skull : upper length 22'2 ; breadth of brain-case ir6 ; 

 nasals, length 7-2 ; interorbital breadth 4-2 ; interparietal, 

 length 4-2 ; breadth 9*2 ; anterior zygoma-root 2'i ; diastema 

 6'2 ; anterior palatine foramina 27 ; combined lengths of m- 1 

 and m- '^ ( m- 3 is unfortunately lost) 2-5 ; length of lower molar 

 series 3'i. 



This species is founded on the specimen referred by Mr. 

 Thomas in 1889* to Ch. gliroidcs^ a reference mainly induced by 

 the peculiar rounded and immature appearance of the skull ; but 

 this appearance has since proved to be a characteristic of the 

 whole genus, and an examination of the teeth shows that the 

 specimen is after all fairlv adult. This being the case, the 

 marked differences in the dimensions of the ears, feet, and tail 

 will readily distinguish it from the older known species.
