RESULTS FROM THE MAMMAL SURVEY. 649 



Mr. Crump obtained 14 specimens belonging to this species. It 

 is possible that the discovery hereafter of intergrading may require 

 that it be treated as a subspecies, but in the complete absence of 

 such at the present date, between it and either palmaritm or 

 rohertsoni, I use a binomial name for it. 



(-B) The Indian Jackals. 

 By R. 0. Wroughton, 



Taking advantage of the temporary stoppage in the receipt of new 

 Survey Collections for examination, I have laid out the whole of the 

 jackals obtained to date by the Survey, amounting to some 140 

 specimens. From this splendid mass of material it is at once evi- 

 dent that there are two main " patterns," viz. : — a " variegated " and 

 a " grizzled." The former occupies the greater part of the penin- 

 sula, a darker form, named indicus, by Hodgson, being found 

 throughout Kumaon, Bengal and Sikkim, and most probably 

 including the Burmese jackal ; a paler form, found through Khan- 

 desh, Central Provinces, Cutch, Kathiawar, and Bajputana (and in 

 which I provisionally include, pending receipt of material from 

 Baluchistan and beyond, the Sind jackal), which I propose to sepa- 

 rate as a subspecies oiindicus under the name l.ola. The " grizzled " 

 pattern is characteristic of the jackal of the West Coast from Bom- 

 bay southwards to Cape Comorin. (I have seen no specimens from 

 the East Coast), and this I propose to describe as a new species 

 under the name naria. The Ceylon jackal, except perhaps in its 

 slightly larger size, is almost indistinguishable externally from that 

 from the adjoining coast of the Peninsula, but an examination of 

 the skull shows that it possesses a tooth character which separates it 

 sharply from ail other Asiatic jackals. It has a supplementary, 

 median interna] rooted lobe or cusp on the third premolar, i.e., on the 

 tooth immediately in front of the carnassial, which is not present in 

 any other species of Canis. To this form I propose to give the name 

 Ganis lanha. 



In one of my earliest reports (Vol. XXL, p. 837), I put forward 

 reasons for keeping the Indian jackal separate from aureus, L., from 

 the Persian Gulf. I confess that now, writing with much more 

 experience, I should write far more cautiously, for the fact is that 

 our material for judging of the true aureus is practically negligible. 

 Nevei-theless I am still of the opinion that we may deal with the 

 Indian jackal, provisionally at any rate, as distinct from aureus, 

 especially as no harm can be done or confusion caused by following 

 that course.
