ö SCIURUS STANGERI. 



catiou between the sides of the body and the abdomen are 

 changed into a pure white. The remaining parts of the belly 

 and the inside of the hind-legs are scantily covered with red- 

 dish hairs. The white rings of the tail have turned red , but 

 the tip of each hair has remained pure white, thus the tail 

 seen from above shows alternate bands of black , white 

 and red. 



Between the two described modes of coloration there are 

 several stages, described as different species by the several 

 authors. 



The ears are covered with short hairs. Whiskers long, black. 

 Eyes dark brown. A red or reddish spot behind the ears.

 There are four molars in each jaw. Incisors very stout, 

 not grooved , bright orange. It must here be remarked 

 that Prof. Peters states in his description of Sciurus cal- 

 liurus Buchholz; ))die oberen Schneidezahne haben eine ein- 

 »zige mittlere Langsfurche. Der vorderste obere Backzahn 

 »ist nur ein ganz feines, nicht über das Zahnfleisch her- 

 »vorragendes Stiftchen". Prof. Peters now agrees with 

 me that this scarcely perceptible impression can hardly be 

 called a longitudinal groove and also that the small fifth 

 supposed upper molar must be considered as a spurious 

 tooth, which is not even placed in the teeth-row. Mo- 

 reover this type-specimen is not fullgrown, the hindmost 

 molars being not yet entirely developed, and finally I 

 saw another skull in the collection under the care 

 of Prof. Peters , which belongs to a specimen entirely
