1878.] of the Genus Eriusicens. 207 



The skull of this species (figs, a to h) is distinguished from that of S. 

 p ictus J and the skull of ^. micropus, by its large second premolar with 

 three fangs, and from the other two species by its great zygomatic breadth. 

 In this latter respect, it resembles E. pictus, but the skull has a considera- 

 bly longer muzzle than in that species, and, as a whole, is not so broad and 

 round. It is considerably broader than E. hlanfordi, with more marked 

 post-orbital contraction, and from JE. jerdoni it is still more markedly 

 separated by its relatively much greater breadth across the zygomatic, and 

 more especially across the base of the muzzle, at the third premolar. 

 The skull is undoubtedly most nearly allied to that of E. hlanfordi, to 

 which it presents a very close resemblance when the adolescent skull is 

 compared with the adolescent skull of the type of that species. But 

 the latter is narrower across the zygomse, and has less post- orbital con- 

 traction, as already stated. It is further separated from the skull of E* 

 jerdoni by its larger teeth, and by the different form of the canine. This 

 tooth in E. hlanfordi, as well as in this species, is less triangular and more 

 sharply pointed than in E. jerdoni, E. niger, E. pieties, and E. micropus, 

 and in this respect differs more in appearance from the first premolar than 

 it does in these last-named species. All of these species are characterized by 

 the presence of two sharp cusps to the canine section of the third premo- 

 lar, while in E. niger described by Blanford, the posterior of these two cusps 

 is entirely absent and its last molar presents only one eminence, while in all 

 the others this tooth has two cusps the inner of which is always the larger. 



The figure in the Illustrations of Indian Zoology was copied froiu one 

 of General Hardwicke's drawings, and on the plate it is stated that the hedge- 

 hog was a species found in the Doab. There are many tracts of country in 

 North- Western India named Doab, but General Hardwicke aj)pears from his 

 paper on Mus giganteus,* in using the term Doab, to have had in view the 

 country lying between the Jumna and Ganges, in which the military 

 Station of Fatehgarh is situated, and where he appears to have been stationed. 

 There he had drawings made of the species of hedgehog which is there 

 common, also of Mus gig ant eus, andof -3f. (JVesoJcia) hardwicJcii = Arvicola 

 indica, Gray. 



I am indebted to the late Mr. Andrew Anderson for many living exam- 

 ples of the hedgehog that occurs about Fatehgarh, and which appears to me to 

 agree with the figure of E. collaris, from the Doab. As in the figure, the 

 chin of these hedgehogs was more or less white, and, in some, the white ex- 

 tended up towards the ear as a kind of collar which, however, is exaggerated 

 in the drawing of E. collaris, in which the contrast between the colours is 

 too marked, and the animal altogether represented too dark. Notvvithstand-
