margin of the meatus auditorius externus. The muzzle is short ; but 

 the palate is much prolonged behind the last molars. 



Its dentition, compared with that oi Herpestes, presents the fol- 

 lowing characters : — is more quadrate and more nearly equal 



in size to ~. -^- is very quadrate. ' is very slightly sectorial, 

 with a large internal tubercle, and resembles the same tooth in the 

 least sectorial Paradoxures. ?i-? is very large, and has a well- 

 developed internal tubercle, with a small cusp behind the large 

 external one, and another small one in front of it, larger, however, 

 than the hindmost outer cusp. -^—' has a rudimentary internal cusp, 

 and both a minute anterior and a minute posterior external cusp. 

 -^ is very small. Besides these four upper premolars and the 

 molars, there is also a small tooth, with a minute basal cusp, 

 placed close behind each upper canine ; yet the skull is that of a 

 rather aged individual. 1 regard this extra tooth as something 

 abnormal. 



j^, is much larger and more quadrate than in Herpestes. jj-| is 



also more quadrate than in Herpestes, and has apparently been 

 quadricuspidate, but is much worn, ^p-j, -p-jj, p-g, and p-^ are much 

 as in Herpestes. Unfortunately I have no means of ascertaining the 

 condition of the anal region. From an examination of the dry skin, 

 the anus appears to me to open into a depression, as in some Her- 

 pestce. Except as above indicated, the characters of Rhinogale are 

 those of Herpestes. 



Length of the head and body about 53"- 1, of the tail 38"- 1. 



The genus Crossarchus^ was founded by F. Cuvier in 1825 for 

 the Mangue, of which he has given a figure (Mammiferes, iii.). It 

 is referred to in Temminck's ' Esquisses,' p. 117. Its anatomy was 

 described by Mr. W. Martin (P. Z. S. 1834, p. 113). The genus is 

 widely spread over Africa : — one species, C obscurus, from Abyssinia 

 to Gambia and the Cameroons, and another, C. fasciatus, from 

 Southern Africa ; a third, C. gamhianus, from Gambia ; and a 

 fourth, C. zebra, from Abyssinia. All have the hair annulated, the 

 ears small and rounded, the tarsus bald ; and they are devoid of a 

 median groove beneath the muzzle. The snout is elongated, hairy 

 beneath, and more or less turned upwards towards the tip. They 

 also have a pollex and hallux ; but these are shorter in C. fasciatus 

 than in C. obscurus. The claws are much elongated. 



In C. fasciatus there are transverse bands or lines, more or less 

 marked, across the back ; these are absent in C. obscurus. The 

 pupil is round. The length of the head and body is 36"-8, of the 

 tail 17"'l, in C. obscurus; and 45"*8 and 22""9 in C. fasciatus. 



The skull of the typical form, C. obscurus, has a bulla on the 

 type of Herpestes, but with its character exaggerated. There is 

 an alisphenoid canal, but very short, and often imperfectly ossified ; 

 but bony processes tending to enclose it may always be detected. 



' This genus includes the genus Mungos, Gray, P. Z. S. 1864, p. 575, ajid Cat. 

 of Carnivora, p. 1 74.
