clear blacky without grizzling. Outer surface of hind legs like back, 

 that of front legs encroached upon by the bluish gray of inner sur- 

 face. Feet slightly more yellow than back, and much more finely 

 grizzled. Cheeks^ chin, muzzle and sides of 7ieck dull ochraceous^ in 

 strong contrast with color of back. Pale lateral stripe dull ocJiraceous 

 btiff"^ very slightly d iff eroit from color of cheeks. Dark lateral stripe 

 of the usual breadth, but hardly as long as in the related red-bellied spe- 

 cies. Ears intermediate in color between cheeks and back. N'o light 

 area behind ear., the hairs in this region colored like those of cheeks, 

 but without grizzling. Underparts and inner surface of legs light gray 

 (very nearly Ridgway's PI. II, No. 9), slightly grizzled with ochra- 

 ceous along median line and everywhere irregularly dulled by the ap- 

 pearance at the surface of the slate gray bases of the hairs. Under 

 surface of tail more ochraceous than upper surface, coarsely grizzled, 

 and not showing as strong a tendency to faint cross-barring. 



Skull. — The skull of Sciurus klossii (fig. 13, 3) is essentially a 

 miniature of that of S. notatus from Singapore. It is, however, 

 broader relatively to its length. Teeth as in S. notatus., due allow- 

 ance being made for difference in size. 



Measurements. — External measurements of type : total length 323 ; 

 head and body 171 ; tail vertebrae 152; pencil 70; hind foot 41 (38). 

 Average of six specimens from the type locality: total length 320 

 (310-330); head and body 176 (171-1S4) ; tail vertebrae 147 (140- 

 152) : hind foot'40 (38-41.6) ; hind foot without claws 37.1 (35-39)- 



Cranial measurements of type : greatest length 42 ; basal length 36 ; 

 basilar length 33.4; palatal length 17.4; diastema 9.S; ^length of 

 nasals 12; breadth of nasals anteriorly 6 ; breadth of nasals posteriorly 

 3; interorbital breadth 16; breadth between tips of postorbital proc- 

 esses 22.6; zygomatic breadth 26.6 ; mastoid breadth 19; breadth of 

 palate between premolars 6 ; depth of rostrum at posterior extremity 

 of nasals 10; mandible 25; depth of mandible at posterior root of 

 large premolar 6; maxillary toothrow (alveoli) S; breadth across both 

 upper incisors at rim of alveoli 4; mandibular toothrow (alveoli) 7.6. 



Specimois examined. — Nine, all from the type locality. 



Remarks. — By its small size Sciurus klossii is separated from all 

 the other blue-bellied members of the S. notatus group cxcei^t S. 

 orestes. I have seen no specimens of this animal, but the original de- 

 scription shows that it differs from the Saddle Island species in several 

 important details of coloration, chief among which are the less fulvous 

 cheeks,' white patch behind each ear, tind ' white "^ lateral stripe. 



1 " Cheeks and sides of muzzle less fulvous than back, instead of more so." 



2 "Sides with the usual lines of black and white."
