 20 ; median length of nasals, 1 1 ; length of upper molar series, 14 ;

This pretty little species, according to Schlegel and Pollen, (1. c.) 

 is found in numbers in the forests in the western part of Madagascar. 

 It also dwells in the eastern part whence M. Goudot sent an example 

 to the Paris Museum. Towards evening it leaves its lodging where it 

 had slept during the entire day. In choosing this it prefers a hole in a 

 tree which has two openings. Often such places are the dwellings of 

 bees, and in that case, the Walouvy, the name the animal bears in the 

 country, separates the hive of the insects from his own nest by a small 

 bunch of straw or dried leaves. The natives pretend that it prefers the 

 society of the bees to rob the honey of which it is very fond. It is 

 much more nimble and agile than the ordinary Lemur, and its leaps are 

 wonderful. Its cry, continually uttered during the night, is very 

 piercing and resembles the syllables ka-ka-ka-ka, similar to the cry of 

 the guinea fowl.
