ICTICYON VEXATIOUS. 191 



as might be expected, preferred raw flesh to vegetable substiinccs, and 

 drank milk with avidity. It was a bold and determined animal, which 

 disliked confinement, and gave out a peevish, yelping sound, uttered at 

 different times in different tones. 



Mr. Tinne, who sent a living example to the Zoological Gardens in 

 1879, has stated his belief that these animals hunt in packs by scent 

 and are exceedingly savage. They are, he further tells us, rarely seen, 

 and though taking readily to water, never frequent the low lands on 

 the coast. 



An interesting account of the anatomy of this animal has been given 

 by Professor Flower *. It is remarkable for its straight caecum f, and 

 for a slight modification in the subdivision of the cerebral convolution;;. 



Our Plate XLIII. is taken from a specimen in the British Museum. 



The colour of this species is generally of a dark brown, but the neck, 

 shoulders, head, and ears are rusty red. The hind quarters, belly, and 

 tail are nearly black ; the inner side of the thighs and the hindermost 

 part of ihe belly, in the British Museum specimens, are also dark, with 

 a few whitish hairs on the belly. The insides of the ears are lighter. 

 The fore limbs are brownish black both within and without. Burmeister 

 represents the hinder part of the belly and the inner side of the thighs 

 of a lighter colour.

Cranial and Dental Characters. 

 The most noteworthy character of the skull of this species is the 

 shortness of the muzzle, which has a much swollen appearance between 

 anterior margins of the orbits.
