Oncoides pardalis tumatumari subsp. nov. 
Type, No. 36318, o& ad., Tumatumari, British Guiana, Sept., 1913; Leo E. 
Miller. 
A form of the pardalis group, distinguished éspecially by large size and dark 
coloration. Nape hairs reversed. ; 
Upperparts with the dark markings very heavy, black greatly predominating; 
ground color tawny on back, passing into grayish white or whitish on the flanks and 
limbs; ventral surface and inside of limbs white heavily marked with black; upper 
‘surface of tail black, with five narrow white rings on the basal half, the apical half 
wholly black above with narrow half-rings of white on the under surface. 
Field measurements: total length, 1230 mm.; head and body, 905; tail vertebre, 
325; hind foot, 180. Skull, total length, 151; condylobasal length, 139; zygomatic 
breadth, 97.5; interorbital breadth, 32; postorbital breadth, 32; breadth of brain- 
case, 54; length of nasals on midline, 31.5, on border 40; maxillary toothrow, 32; 
upper carnassial, 16.5 X 8.5. 
Various names have been given to South American representatives of 
the pardalis group,! based on specimens from unknown localities, often 
living animals in menageries, and unidentifiable. In view of this fact it 
seems better to give a new name to the British Guiana form than to attempt 
a reference of it to any of the vaguely described forms from “Brazil” or 
“South America.” 
Eptesicus chapmani sp. nov. 
Type, No. 37057, 9 ad., Lower Rio Solimoens, April 30, 1914; Leo E. Miller. 
Roosevelt Brazilian Expedition. 
Similar in coloration to Eptesicus dorianus (Dobson) but larger; smaller than 
EK. hilarit (1. Geoffroy), and quite differently colored — less suffused with fulvous 
both above and below. ° 
Upperparts uniform bistre, the extreme tips of the hairs barely perceptibly lighter; 
underparts similar but lighter, the tips of the hairs distinctly grayish buffy; mem- 
branes blackish. 
External measurements (type), expanse, 292 mm.; total length, 95 ; head and 
body, 55; tail, 40; hind foot, 8; ear from crown, 10. Type and 5 topotypes, ex- 
1 Cf. Mearns, Proc. U. 8. Nat. Museum, XXI, No. 1286, pp. 237-249 (especially, in 
this connection, pp. 237-241). The type locality of Felis chibigouazou. Griffith (* South 
America ’’) may be considered as Chapada, Matto Grosso, Brazil, on the basis of Mearns’s 
detailed description of the species from Chapada specimens.
