The type of L. flavifrons is in the British Museum, and the follow- 

 ing is a description of it. Pale yellowish band across forehead ; nose 

 bright rufous ; top of head, body above, and beneath ears rufous, dorsal 

 line darkest ; rump paler, more reddish ; shoulders yellowish ; outer 

 side of limbs rufous like head ; hands and feet dark rufous ; chin and 

 throat whitish; inner side of limbs, neck and body beneath yellowish, 

 tail rufous. 



A second specimen also a female, is very much darker in color, 

 being bright chestnut on head and body, dorsal region and hands 

 blackish chestnut, feet and tail rufous. While having a general 

 resemblance to each other, these two examples differ greatly in depth 

 and shade of color. 



Schlegel in his monograph of the Lemurs was the first to call atten- 

 tion to the fact that it was not the animal that was most common in 

 collections, and of a rather large size which should bear the name of 

 mongoz given by Linnaeus, but a smaller form distinguished in the 

 male by rufous patches beneath the ears, extending sometimes on to the 

 throat, and with a whitish face and nose. Later Forsyth-Major in the 

 Proc. Zool. Soc. Lond., 1901, p. 249, published a paper in which he 

 showed very conclusively that the wrong animal had been accorded the 

 Linnaean name of mongoz, and agreed with Schlegel that the smaller 

 rufous-cheeked animal should rightfully bear the appellation. The 

 female is very similar to the male in general appearance, but lacks the 

 rufous coloring ; and the patches on the side of head and throat, called 

 whiskers by Schlegel, are white, and she is rather lighter on the under 

 side of the body. Besides Madagascar, this species is a native of the 

 islands of Anjuan, (Johanna), Mohilla, and Nossi-be. 



According to Schlegel and Pollen, (1. c.) "this species inhabits the 

 forests which extend from the bay of Diego- Juarez to the bay of Bam- 

 betoc, also the forest of Loncoube in the island of Nossi-be." The 

 animals go in troupes and keep to the highest trees. Ordinarily they can 

 be seen towards evening, and then their voices are head in loud cries, 

 for at that time they are exceedingly noisy. Sometimes when danger 

 approaches these cries are changed to growling. Their agility in leap-
