or ochraceous-buft' ; mantle brighter than in (/i^minoruiu, varying 

 from bright hazel to almost ochraceous-buti'. Forearm 121- 

 13;Vo mm. Hah. Engano. 



Sl-iiU and teeth. — Skull averaging decidedly smaller than in 

 fjeniiiiorum and hpieliis, but scarcely distinguishable from that of 

 small individuals of cat/ai/ann-'i. Teeth averaging smaller than in 

 i/eniiiwnon ; p', length 'd-7—i'6 mm., against 4"2-4'8. Most of the 

 teeth are absolutely smaller than in h-piihts. 



External dimoviions. — Pt. h. emjanus averages in every respect 

 smaller than any other race of the species ; forearm 1 21-133'5 mm., 

 against 128-145-5 in all other races; third metacarpal 82-91, 

 against 87-{'7-5 ; lower leg 54-60, against 57'5-(iH ; calcar 1 1-14, 

 against 13-18. The sexes do not seem to differ appreciably in 

 size; in six adult males the forearm measures 121, 125"5, 12.'i'."), 

 ]28*5, 129'5, and 133-5 mm., average 127'3; in seven adult 

 females 123-5, 126-5, 127, 127-5, 128, 128, and 120, average 

 127-1. 



Colour. — rT ad., paratype, teeth slightly worn, 2 Nov. 1904 

 (U.S. N. M. no. 140960). Back and rump blackish brown rather 

 thickly mixed with silvery greyish white, ])roducing the total effect 

 of a dark shade of hair-brown very similar to that of an average 

 specimen of r/emi)iormn : rump very slightly washed with a paler 

 brown. — Breast and belly blackish brown, thinly but distinctly 

 sprinkled with shiny silvery grey hairs. — Mantle bright hazel, in 

 some places lightened by golden ochraceous-buff, in others clouded 

 with cinnamon-rufous, darkening on sides of neck to chestnut, 

 this again on foreneck to dark seal-brown. Base of hairs of mantle 

 not differing. — Crown and sides of head light greyish hair-brown ; 

 individual hairs silvery whitish grey, everywhere mixed with 

 blackish or dark brown hairs ; throat similar in colour to foreneck. 



The specimen described above is one of the most plain-coloured 

 in the series, but it scarcely represents the average coloration in 

 this form ; in most individuals the back, head, and undcrparts are 

 more or less conspicuously suffused with russet or light tawny 

 ochraceous. The individual variation may be briefly summed up 

 as follows : — 



Back and rump : owing to the greater or less amount of sprink- 

 ling with shiny silvery greyish-white hairs, the general colour 

 varies from dark hair-brown (pale sprinkling comparatively thin), 

 through greyish hair-brown, to mouse-grey. Some individuals are 

 scarcely, or only very slightly, washed with russet on back and 

 rump ; others are conspicuously suffused with light russet or 

 ochraceous-buff along edges of membranes and inner sides of tibije, 

 but only slightly so on middle of back and rump ; in others the 

 russet suffusion extends over the whole of the back and rump, 

 making the central portion mars-brown, the lateral edges along 

 membranes tawny ochraceous-buff; one specimen ( J ad., 140968), 

 representing the extreme in pale colour, is almost wood-brown 

 edged with buffy along membranes. — Breast and belly: in some 

 tpecimeus api>roximately seal-brown slightly sprinkled with shiny
