1918.] C. BoDEN Kloss : Notes on Hares. 93 



The skull, thouoh fully adult, ^ indicates an animal so much smaller 

 than the last and following; that, if typical, it might be regarded as sub- 

 specifically distinct in which case Hodgson's name aryuheftersis would 

 apply {Calcutta Jounwl of Natural History, IV, p. 293 — Nepal). 



No. 10327a. Old mounted male from Agra District much faded 

 and worn. 



Tail ochraceous above throughout. 



Upper incisors large, the groove bifurcating fairly regularly, the 

 posterior edge concave, branches of medium length, stem moderately 

 broad (fig. 6). 



No. 7244. Adult skin and skull from Gaya District, Bihar (F. 

 Field coll.). 



Colour less bright than the Nepal specimen, back and sides approach- 

 ing buf? ; a considerable amount of whitish on the sides of the head ; 

 both sides of the hind feet also pale. Hairs of the upper side of tail 

 ochraceous distally, dark brown basally. 



Skull large, nasals somewhat rounded posteriorly, post-orbital 

 processes of medium size and not touching the frontals behind : palatal 

 foramina large and palate bridge broad, anterior feet of zygomata very 

 large (12-5 mm. long). 



Incisor grooves showing greater development than the last : the 

 stem is narrower in proportion to the spread of the branches of which 

 the right incisor exhibits two and the left three, the extra branch being 

 median and small (fig. 7). 



No. 10174b. Skin from Manbhum, Bengal (R. C. Beavan coll.). 



In every way as brightly coloured as the Nepal specimen with the 

 hairs of the upper side of the tail ochraceous throughout except for 

 some dark tips. The hair below the digits is dark tawny, in marked 

 contrast to the ochraceous limbs ; but this feature is probably fortuitous. 



No. 10328a. Skin from Manbhum, Bengal (R. C. Beavan coll.). As 

 the last except that the hair beneath the digits is not dark. 



No. 7317. Portion of skin with perfect skull from Calcutta. 



The fragmentary skin indicates an animal nearly as bright as the 

 Manbhum individuals. 



Skull with nasals pointed posteriorly, and rather small post-orbital 

 processes not approaching the frontals. Palatal bridge narrow with 

 a posterior median spine, mesopterygoid space broad, bullae like the 

 last but more globose ; molars small. 



Incisor grooves bifurcating with well developed branches completely 

 filled with cement (fig. 8) : Very like those of a specimen from the 

 Jumna River figured by Lyon {I. c. s., fig. 10) but branches more elongate. 



Lepus ruficaudatvs seems to be a species in which the incisor grooves 

 are normally bifurcate but also develop three and four branches as in 

 the animals from the Punjab and Rajputana figured by Forsyth-Major 

 (I. c. s., figs, xxiii and xxiv) : for Punjab material the name hircjosa has 

 apparently been proposed by Gray. 



* Specimens are here regarded as fully adult when tlic frontal suture is largely obli- 

 terated : otherwise they are called nearly adult or sub-adult.
