664 THE SECRETARY ON ADDITIONS TO THE MENAGERIE. [Dec. 1, 



and much more convex anteriorly, and the posterior prolongation of 

 the postorbital process is not in contact with the skull behind, 

 whereas in L. dayanus this prolongation joins the skull so as to leave 

 a foramen behind the postorbital process, as in L. mediterraneus, 

 which has on this ground alone been considered generically distinct 

 from other Hares by Dr. Gray (Ann. & Mag. Nat. Hist. 1867, ser. 3. 

 xx. p. 222). In the skull of L. dayanus which I have examined, 

 the postorbital process is not anchylosed with the frontals behind 

 the foramen ; but it may very probably be so in older animals. 



All the teeth are smaller than in L. ruficaudatus ; and the upper 

 incisors appear very indistinctly grooved in the new species, and, so 

 far as I can judge, never have the raised ridge along the front part 

 of their inner edge, so conspicuous in old skulls of L. ruficaudatus. 



The measurements of a dried skin can only be approximative. 



The whole length from the nose to the rump appears to be about 

 18 inches. The ears are about 4| inches long from the orifice to 

 to tip, and nearly 2g broad ; in fresh specimens they would be 5 

 inches long at least. The tarsus and hind foot to the end of the 

 claws measure just 4 inches: this measurement, of course, would be 

 the same in the living animal ; and I find it constant in three spe- 

 cimens. The skull extracted is imperfect behind ; the breadth 

 across the hinder and broadest part of the zygomatic arches is 1*55 

 in. across the frontal bones where narrowest, between the foramina 

 behind the postorbital processes 0*47 ; length of suture between 

 the nasal bones PI. 



This species is apparently the common Hare of Sind. Dr. Day 

 has brought several skins from near Sakhar. 



December I, 1874. 

 Dr. A. Giinther, F.R.S., V.P., in the Chair. 



The Secretary made the following report on the additions to the 

 Society's Menagerie during November 1874 : — 



The total number of registered additions to the Society's Mena- 

 gerie during the month of November was 79 ; of which 4 were by 

 birth, 3S by presentation, 18 by purchase, 1 received in exchange, 

 and 18 received on deposit. The total number of departures during 

 the same period, by death and removals, was 104. 



The most noticeable additions during the month were: — 



1 . An example of Humboldt's Saki (Pithecia monachus), purchased 

 November 2nd. Of this rare American Monkey we have previously 

 received only one living specimen, which was figured and described 

 by Prof. Flower, P. Z. S. 1862, p. 326. 



2. A fine male of the larger form of the Patas Monkey (Oercopi- 

 thecus ruber ?), presented by Dr. R. F. Mayne, on the 3rd November. 

 Dr. Mayne, in reply to inquiries, tells me that this monkey was 

 purchased at Lagos, West Africa, where he informs me this species is
