240 DR. A. GUNTHER ON THE SEPID^E. [Mar. 7, 



smallest grown by any of the Deer, those of Cervus rufinus of 

 the Andes of Ecuador and Columbia being, I believe, considerably 

 larger. It will be observed that the antlers are perfectly simple, 

 slightly curved, unbranched, and terminate in a point. The length 

 of the antlers shed in November 1869, is 2'5 inches, that of those 

 shed in December 1870, 2- 8 inches.

 p. 669. 



I regret to have to announce the recent loss of the two fine 

 specimens of this new Kangaroo. One of these I now exhibit, 

 that received July 20th, 1870. It agrees generally with that 

 figured and described /. c, but is of a nearly pure white on 

 the throat and body beneath, and has the end of the tail black. 

 The upper back is of a rich vinous colour, which is also con- 

 tinued over the shoulders, nape, and top of the head. The hands 

 and feet are black. The measurements of this specimen are : — 

 whole length, from nose to base of tail, 40 inches ; tail 26 inches ; 

 length of ears nearly 5 inches ; of tarsus to end of longest toe 

 11. The muffle of M. erubescens is quite naked; and the species 

 therefore belongs strictly to the section Halmaturus of Mr. Water- 

 house's arrangement. 



The skull of the specimen (fig. 5, p. 239) shows that the animal 

 was not yet adult, the third and fourth molars being not yet in their 

 places. In general form it resembles most nearly that of Macropus 

 rufus. The third incisor, as in that species, has but one shallow 

 vertical groove, placed rather in front of the middle (see fig. 6, 

 p. 239) ; but the whole tooth is wider and not so deep as is repre- 

 sented in Mr. Waterhouse's figure of the corresponding tooth in 

 Macropus rufus (Mamm. ii. pi. 5. f. 3). 



2. List of the Lizards belonging to the Family Sepidce, with 

 Notes on some of the Species. By Dr. A. Gunther, 

 F.R.S., F.Z.S. 



[Eeceived February 20, 1871.] 



The family Sepidce, as defined by Dr. Gray (Catal. Lizards, p. 121), 

 forms a perfectly natural group of Lizards, peculiar to the African 

 region, including the countries round the Mediterranean, Madeira, 

 the Canaries, Madagascar, Mauritius, but not the Seychelle Islands. 

 This family is also remarkable for exhibiting the most perfect trans- 

 ition from species with four well developed, though always feeble, 

 limbs, to others in which only minute external rudiments of these 

 organs are perceptible. Several additions having been made to this 

 family during the last twenty years, I have thought it useful to 

 compile a list of the species known at present, drawing also attention 

 to those which are desiderata for the British-Museum collection.
