in all its dimensions ; and has a recurved upper angle, which is entirely wanting in 
the fossil. The masseteric fossa is also larger and deeper in the fossil, and the 
pedicle of the condyle wider and flatter ; in consequence of which there is a smaller 
upward bend of the inferior border below the ascending ramus than in the. recent 
species. In these respects the pleistocene Cyon europceus 1 comes nearer to the fossil, 
though the angular process is smaller than in the latter. The European species is 
broadly distinguished by the absence of m. 3. 
Dublin cranium . — The cranium of which the hinder cheek-teeth of the left side 
are represented in the woodcut on the last page, as already observed, is associated 
with the mandible, of which a portion is represented in the same figure, and, 
therefore, belongs to Canis cautleyi. The cranium is broken off anteriorly in front 
of pm. 3 , and is not in a condition to afford a good figure. It presents a strong 
sagittal crest, and a deep groove along the mesial fronto-nasal line ; the post-orbital 
processes of the frontals are large, and much curved downwards towards the 
zygomatic arches. Anteriorly it is a good deal crushed : but the hinder part of the 
palate is fairly perfect, and shows pm. 3 , pm. 4 , m. 1 , and m. 2 . The summits of the 
two former are broken off, but the teeth are otherwise perfect, and scarcely touched 
by wear. The whole skull and teeth are essentially • wolf -like in form. Their 
dimensions are compared below with those of C. pallipes , 2 viz. : —

Indian Museum maxilla . — In figure 3 of plate XXXII. there is represented the 
left maxilla of a wolf, formerly in the collection of the Asiatic Society of Bengal, 
but now transferred to the Indian Museum. It is alluded to in the Journal of the 
Society 3 as having been obtained by the late Col. Colvin from the Siwaliks of 
Dadupur. In Messrs. Falconer arid Walker’s Catalogue of the Society’s Vertebrate 
Fossils, 4 the specimen is alluded to as follows : — u Canis . — Upper maxillary, left side, 
comprising a part of palate and zygomatic portion of orbit, with 4 teeth in situ , the 
three posterior of which are entire, agreeing exactly in form with those of Canis 
lupus , but a little larger.” In its present state pm. 3 has been broken off ; and the
