it measured 9 inches in length — according to Reimann, 6 inches. In 

 H. hrumiea it is 8g inches long, whilst in Proteles it is short and 

 globular, measuring only one inch in length. The large intestine 

 exclusive of csecuin measures 26| inches, and is i)rovided with 

 thick muscular walls. In H. striata the great gut measures 3 feet, 

 and in H. brunnea 2 feet 6 inches in length, whilst in Proteles, ex- 

 clusive of the caecum, it measures 14 inches. In connexion with 

 the lower end of the rectum are two anal glands, which pour their 

 contents into a pouch situated immediately above the anus. These 

 glands, which have been previously described', resemble more closely, 

 both in respect of number and size, the corresponding structures in 

 Proteles than those of any other species oi Hyana.

The following Table shows the length of the intestines, together 

 with that of the body, in the different species of Ili/cena ; but it is 

 right to state, with reference to the latter measurement oiH. crocuta, 

 that we have taken it to be the same as in //. brunnea, having 

 unfortunately omitted to ascertain the dimensions of the specimen 

 examined ; the measurements of the other species are those of Dau- 

 benton, Murie, and Flower respectively. 



From this table it appears that in H. striata the length of the 

 whole intestine from pylorus to anus is to that of the body as 8 to 1,
