black with a light punctulate mixture of tawny ochraceous; feet, toes,

ferruginous with or without irregular white markings on the throat 
and chest; chin and sides of throat finely mixed dusky and clay 
color, only slightly paler than cheeks; upper side of tail black proxi- 
mally and terminally, the intervening part clear ferruginous (the hairs 
of this part very narrowly or quite broadly black basally); terminal 
black occupying nearly or quite one-third of length; under side of

est length 68.3; basilar length 45.5; zygomatic breadth 33.6; inter-

Remarks. This form, like typical versicolor, is doubtless highly 
variable, but the three specimens examined differ constantly from any 
of a considerable series of typical versicolor in at least three characters, 
increased black across the shoulders and nape, increased black on the 
end of the tail, and decrease or entire absence of black on the feet and 
forelegs. In versicolor, there is only an inch of terminal black in the tail at 
the most and many specimens have the tail ferruginous to the very tip; 
while in zulie the terminal black amounts to as much as three inches. 
_ The only other form likely to be related is Scturus variabilis morulus 
of Panama, which is said to have ‘‘most of the hairs above, 
ringed-blackish at base, then ferruginous, and blackish again at tip’’; 
whereas, in zudie the hairs of the back are pure black to the roots. 
Sciurus tobagensis sp.-nov. 
Type from Tobago Island, Caribbean Sea. No. 14,954 Field Mu- 
seum of Natural History. Adult female. Collected May 12, 1892, by 
W. W. Brown, Jr. 
Characters. Similar to Sciurus chapmani, with which it agrees 
in size and general coloration, but terminal color of hairs of tail paler 
and subterminal black more extensive; sides of face slightly more 
richly colored. Color of tail much as in S. hoffmanni, but size de- 
_ cidedly smaller. The subterminal black in the hairs of the tail forms 
a well-defined lateral stripe about 5 mm. in width extending the 
length of the tail to a broad black tip 25 to 50 mm. in width. In chap- 
mani, the black lateral stripe and subapical black is much reduced
