MAMMALIA RODENTIA. 263 



S. M tiller and H. Sclilegel have given the description of 

 the Sciurina that occur 011 the islands of the Indian Archi- 

 pelago. It is to be found in the 10th Hefte der Verhaudel. over 

 de natuurl. Geschied. der Nederl. overzeesche bezitt Zoologie. 



No mention is made whatever in this of my labours upon the Sci- 

 urina in Schreber's works, which I the more regret, since many doubts 

 entertained by Miiller and Sclilegel might have been thereby removed, 

 while to them there was naturally a far greater supply of materials at 

 command than to myself, as also opportunities for observing habit and 

 geographical range, which to me were wholly wanting. The fifteen species 

 of Sciuriua, which they admit as belonging to the Indian Archipelago, are 

 divided in the following manner : (a) Large species without lateral stripes ; 

 tail very long, clothed with two distinct rows of very long hairs ; skull broad 

 and strong ; muzzle short, broad, and arched ; above as well as below, upon 

 either side, four molar teeth : Sc. bicolor, hypoleucus, and ephippium. (b) 

 Species of median size, usually provided with long stripes upon the sides 

 of the body ; tail thickly covered with hair, yet less distinctly tripinnated 

 than in a, and longer than the body ; in front of the first true molar there 

 is one of very small size : Sc. Idppurus, rubriventer, n. sp., Rafflesii, vitta- 

 tus, niyrovittatiis, leucomus, n. sp., modestus and murinus, n. sp. (c) Species 

 very small, tail shorter than the body, molar teeth as in b : Sc. exilis and mela- 

 notis. (d) Species of median size, tail shorter than the body ; muzzle more or 

 less elongated ; molar teeth as in b ; living mostly upon or near the earth ; 

 colour dark ; tail slightly bicurvate ; Sc. insignis and laticaitdatus. With 

 the exception of the three new species, the rest have been already described. 

 Of the former, which belong to Celebes, and have been published by Forsteu, 

 merely the diagnoses have been given, as follows : (1) Sc. ritbriventer : 

 size, form, and colour in general like that of Sc. hippurus, but the ears 

 longer and covered much more closely with black hairs of very great length, 

 and thus projecting far beyond the ears ; the reddish brown of the lower 

 parts not only extends over the inner but also outer side of the paws ; caudal 

 hairs black, surrounded towards the apex with broad rings of a feeble red- 

 dish brown, tint. (2) Sc. leucomus : size and form as in Sc. vittatus and 

 nigrovittatus ; cars lined internally with brownish yellow, posteriorly with 

 long black hairs, projecting far above the ears ; colour of the upper parts 

 and outer side of the feet olive-brown ; the hairs mostly marked with rusty- 

 yellow rings, and having in part black apices ; tail dappled with these 

 three colours, behind the ears a large white spot : under side of the body 

 rust-coloured, inclining to reddish brown. (3) Sc. murinus : general appear- 

 ance and form as in Sc. modestus, but somewhat smaller, the tail being rather 

 shorter, cars less hairy, and the colour more uniform ; above, wliitish gray, 

 and the hairs with whitish yellow points ; beneath, ashy-gray.
