With reference to the relative lengths of the small and great intestines, the table shows that in H. striata the length of the small intestine is to that of the great as 6\ to 1, in H. brunnea as 81 to 1, in Proteles as 7j to 1, and in H. crocuta as 12-jL- to 1. //. crocuta therefore differs from the other species named in the greater length of the small intestine as compared not only with that of the body, but also with that of the great intestine. Liver.-The liver is large. In accordance with Prof. Flower's1 method of description, we distinguish two hepatic segments, a right and a left, each of which is divided into lobes. The left segment is the smaller, and is divided, by means of a well-marked lateral fissure, into a lateral and a central lobe. Of these the former is much the larger and of an oval form, whilst the latter is triangular, with the apex directed backward. The right segment of the liver, larger Liver of Hycena crocuta. U, umbilical fissure ; Llf left lateral fissure ; Rlf right lateral fissure ; l.l, left lateral, and l.c, left central lobe ; r.l, right lateral, and r.c, right central lobe; S, Spigelian lobe; C, caudate lobe ; G.B, gall-bladder. than the left, also presents a well-marked lateral fissure, by means of which the right central is cut off from the right lateral lobe. On the visceral aspect of the former is a deep cystic fissure which accommodates the gall-bladder, and divides the central lobe into 1 Medical Times and Gazette, vol. i. 1872, p. 293. |
