1 8 SMITHSONIAN MISCELLANEOUS COLLECTIONS [vOL. 45 



with an indistinct darker wash along median Hne. Tail like back, 

 but more coarsely grizzled, its terminal black area occupying about 

 one-fourth total length of tail. 



Skull and teeth. — The skull closely resembles that of Sciurus 

 adangensis in form, but in size it is distinctly larger. It is smaller 

 and less elongate than the skull of Sciurus davisoni. The teeth 

 show no peculiarities. 



Measurements. — Measurements of type: total length, 490; head 

 and body, 285 ; tail vertebrae, 205 ; hind foot, 51 (47) ; skull, greatest 

 length, 55; zygomatic breadth, 33; median length of nasals, 16.8; 

 greatest breadth of both nasals together, 7.8. 



Specimens examined. — Five, all from Sullivan Island. 



Remarks. — The series shows no variation worthy of note. The 

 color pattern in this species is like that of the mainland animal, and 

 the neck and side markings show no tendency to become obsolete. 



SCIURUS DOMELICUS sp. nov. 



Type. — Adult female (skin and skull). No. 104,381, United States 

 National Museum. Collected on Domel Island, Mergui Archi- 

 pelago, February 24, 1900, by Dr. W. L. Abbott. Original num- 

 ber, 322. 



Characters. — Like Sciurus sullivanns but colors throughout 

 slightly darker, reddish lateral areas spreading over whole ventral 

 surface, black tip of tail longer, and skull with narrower, more 

 elongate rostrum. 



Color. — Type : The colors are essentially as in Sciurus sullivanus 

 but are all a shade darker, the red of the sides and neck approach- 

 ing cinnamon-rufous. Entire underparts heavily washed with dull 

 cinnamon-rufous, a trace of grizzled gray, however, remaining on 

 chest. Legs, feet, and face darker gray than in the related form, 

 but rather lighter and producing a more decided contrast. Tail as 

 in Sciurus sullivanus except that the black terminal area is noticeably 

 longer. 



Skull and teeth. — The skull diiTers from that of Sciurus sullivanus 

 in its narrower general form, and in the greater elongation of the 

 rostrum. Its resemblance to the skull of Sciurus lancavensis is very 

 close. 



Measurements. — Measurements of type : total length, 420 ; head 

 and body, 210; tail vertebrae, 210; hind foot, 51 (48) ; skull, greatest 

 length, 54; zygomatic breadth, 31; median length of nasals, 16.4; 

 greatest breadth of both nasals together, 7.
