than the anterior limbs. This becomes much deeper on the hands (hinder), which 

 are fulvous, except on the fingers, where there is a very considerable intermixture 

 of black, the terminal tufts, equally long with those of the anterior hands, being 

 as in them fulvous. The under surface is white throughout, with the exception 

 of the hinder part of the throat, where it is of the same colour with the sides of 

 the body. The hairs are generally long, silky, waved, erect, and glossy. On the 

 crupper, they are shorter and more dense, offering a sort of woolly resistance. 

 On the tail, they have the general character of those of the body, but are con- 

 siderably shorter." 



Length of the head and body, 1ft. 9 in. ; of the tail 1ft. 5in. 



" The external characters, by which Propithecus is distinguished from Lemur, 

 are its shorter muzzle, terminated by more approximate nostrils, the upper 

 margin of which appears to be slightly lobulated ; its rounded ears ; the marked 

 disproportion in length between its hinder and anterior extremities ; the greater 

 length of its hands, especially of the anterior; the shortness of its anterior 

 thumb, which is also placed much farther back ; the marked abbreviation of the 

 anterior index ; the development and power of the hinder shank, which is nearly 

 an equal opponent to the whole of the fingers ; and the comparative shortness of 

 the hairs by which the tail is covered."— Habitat Madagascar, where it is stated 

 to be rare. Of its history nothing is known. In Mus. Zool. Soc. 



Now, if we compare the description of the Long-tailed Indri, with that just 

 given of the Diadem Propithecus, we shall not fail to perceive the resemblance, 

 notwithstanding some points of variation, and an inferiority in size. Length of 

 head and body about 15 inches. The body has a stout appearance, from the 

 thickness of the fur ; the head is less elongated than in the Short-tailed Indri ; 

 the forehead is broad ; the eyes large, the ears short and concealed under the fur, 

 which is of a deep yellow or fulvous; thumb of the hinder hands large and strong, 

 with a broad nail, thin and flat ; first toe united at the base to the thumb, by a 

 black membrane. Fur soft and woolly; general colour yellow; under surface 

 generally, and inside of limbs, dull white tinged with yellow ; crupper, around 

 the root of the tail, white. A black mark covers the nose and part of the face, 

 terminating in a point on the forehead ; hind feet covered with mingled grey and 

 yellow hairs; fingers and nails black. — Vide Desmarest, and Geoffroy in 

 Annates du Museum, xix., p. 158. — The chief differences between this animal 

 and the preceding, it will be seen, consist in the inferiority in size of the latter, 

 in the arrangement of black on the face, and the presumed absence of this colour on 

 the back of the neck and shoulders, together with the absence to the white band 

 across the forehead, bounding anteriorly a black cap. Still, in the general yellow 

 tint pervading the limbs and body, in the shortness of the ears, the abbreviation 

 of the muzzle, and in the quality of the fur, the coincidence is remarkable ; inso-
