it is only the young males that are furnished with them. In these 

 too they can only be considered in the light of half-developed germs ; 

 for the cartilaginous part which covers the palate and the upper jaw 

 entirely conceals them. 



It is the Ant. montana, which I discovered in 1824 in the neigh- 

 bourhood of Sennaar, and of which I published in my ' Zoological 

 Atlas ' the figure of an adult male, that is provided, in its youth, with 

 these anomalous canine teeth : the adults of both sexes, and the 

 young females, are destitute of them. I observed, in my last journey 

 in Abyssinia, many individuals of this species in the valleys in the 

 neighbourhood of Gondar : it is far from rare in that locality, but 

 the jungles mingled with thorns, which are its favourite retreat, ren- 

 der the chase of it extremely difficult. 



At the time of the publication of my description of this new spe- 

 cies, in 1826, I was possessed of only a single adult male, and there 

 were consequently many deficiencies in my account of it. I am now 

 enabled to add to this notice that the females of this species are 

 always destitute of horns ; that both sexes have, in the [groins] two 

 rather deep pits covered by a stiff bundle of white hairs ; and finally 

 that the species lives in pairs in the valleys of the western part of 

 Abyssinia, where it takes the place oiAnt. Saltiana, an animal which 

 it exceeds in size by nearly one half. These two species are called by 

 the natives Madoqua, by which name the Abysslnians also designate 

 the Ant. Grimmia, which equally constitutes a part of the game of 

 that country, so rich in different forms of the Ruminant order. — E. R. 



A note by Mr. Martin was subsequently read, in which it was 

 stated that it had once occurred to him to obsen-e a rudimentary 

 canine tooth in the female of a species of Deer from South America, 

 the body of which had been sent to the Society's house by Sir P. 

 Grey Egerton, for examination. Having noticed an enlargement of 

 the gum of the upper jaw, in the situation in which a canine tooth 

 might possibly be supposed to exist, he cut into it, and found the 

 germ of a canine tooth, about 3 lines in length, imbedded in the gum, 

 and destitute of fang.
