186().] MR. ST. GEORGE M1VART ON MICRORHYNCHUS. 15.3 



part of the thighs and around the anus whitish ; the tail and the 

 paws are of a reddish brown. The hairs of the back are grey at the 

 base, then reddish, rather darker in the nape of the neck. The ears 

 are round, short, and covered with hair. The length of the head 

 and trunk measures 0"3 ; the tail to its end, without the hair, 0*25 ; 

 the posterior limbs, to the heel, measure 0-21 ; the anterior limbs 

 to the end of the fourth finger measure 0-16. The fourth finger is 

 longest, both in the anterior and posterior extremities. 



" The barbarous name Avahi will probably meet with little accept- 

 ance. On that account we believe that we ought to accept the name 

 Habrocebus, proposed by Wagner, and which alludes to the soft and 

 woolly hair. At the same time it is uncertain whether it is more 

 than a subdivision of the genus Lichanotus, and it is also uncertain 

 whether Propithecus diadema should be placed in the same °-enus 

 with it." b 



So far Prof. Van der Hoeven. 



Dr. Ch. Coquerel* informs us that the Indri is called by the 

 natives Batakoton, the former name merely signifying behold ! "or, to 

 use Dr. Coquerel's words, "tiensl void I regardel le voilal" 



With regard to Microrhynchus he says that (unlike the Indri, 

 which appears confined to the mainland "of Madagascar) it is found 

 in the great forest of Tsasifoutt, in the Island of St. Mary, and that 

 it is known to the natives by the name Ampongui. He adds that it 

 is more decidedly nocturnal than the true Lemurs, and that in com- 

 parison with them it is a stupid animal. 



A fine skin of an adult individual (containing a nearly perfect 

 skull and most of the bones of the limbs) was obtained in Mada- 

 gascar by Mr. Gerrardf, and has been kindly placed in my hands 

 for description by Dr. Sclater. 



This skin answers to the description, above quoted, of Prof. Van 

 der Hoeven ; but it has (what he does not mention or represent in 

 his figure) a very distinct transverse whitish band across the forehead, 

 which is the more marked because the hair immediately in front of 

 and behind this band is darker than on the rest of the body. The 

 general coloration is brighter and darker than in the young skin in 

 the British Museum, and the transverse light frontal streak, with its 

 dark margins, better defined. The hands and feet are of a rusty brown, 

 and the tail rufous ; but the fur of these parts is dark grey at the 

 base, as indeed it is all over the body, except at the white patches on 

 the backs of the thighs, where most of the hairs are light-coloured 

 for their whole length. The face is almost entirely covered with 

 short hairs of nearly the same tint as the fur of the arms. 



The ears are short and rounded, nor do they appear to be at all 

 tufted. The fourth digit is the longest in both the anterior and the 

 posterior extremities. 



In form M. laniger is remarkable for its very long hinder limbs, 

 which it shares with the other Indrisince, and for its long tail, in 

 which it agrees with Propithecus. Perhaps, however, its most pecu-
