The fifty squirrels of the vittatus group taken in the archipelago 

 appear to be referable to Sciurus peiiinsularis. They are from the 

 following- islands: Sinkep (8), Penuba (8), Linga (5), Sebang (4), Sang- 

 lar (7), Bintang (4), Batam (2), 8ugi (9), and Little Karimon (3). 

 While the series diti'er slightly among themselves, I can find no tangi- 

 ble characters on which to separate the forms occurring on the various 

 islands. In general the specimens from the southern localities tend to 

 be paler than those from farther north. They all agree with Sciurus 

 'peni)isul<iris and differ from S. vitt((tus in the color of the cheeks and 

 underparts. In none is there a trace of clear red in the tail. For 

 measurements see ta))le, page 2(14. 



RHINOSCIURUS LATICAUDATUS (Muller and Schlegel.)

A very old male, snared by natives, was procured on Linga Island 

 August 28, 1901. I have not been able to compare it with the Bornean 

 animal. Its measurements are: Total length, 278 mm.; head and body, 

 213; tail vertebras, 65; hind foot, 11 (38.5); skull, greatest length, 56; 

 basal length, 49; basilar length, 46.4; nasals, 20.4; greatest breadth of 

 both nasals together, 5.8; diastema, 16.4; zygomatic I)readtli, 28; least 

 interorbital ])readth, 13.8; mandible, 35; maxillary tooth row (alveoli), 

 11.8; mandibular tooth row (alveoli), 11.
