but tlie walls of the triangular interdigital depression leading 

 to the gland were very spaisely clothed with quite short hairs, 

 much fewer and shortei- than in C. dorsalis. Only at the 

 infei-ior margin of the side walls of the depression w'ere there 

 long hairs overlapping the proximal edge of the nail of the 

 hoof. The gland itself consisted of a large laterally compressed 

 sac, very much like that of G. maxwelli, but with the narrowed 

 portion much shorter and wider, and with no long hairs 

 jutting from the orifice, the walls of the sac being clothed with 

 very short sparsely set hairs, like those of the triangular de- 

 pression. As in G. maxiveUi, the glandular tissue could be traced 

 not only over the walls of the gland itself but from the commence- 

 ment of the anteiior web of the hoofs to that of the posterior web. 

 There was, however, no secretion in the glands. 



My observations on this species agree with those made on 

 ;S'. grhiimi by Ogilby, who stated that both inguinal glands and 

 pedal glands were present, the latter being small. Owen also 

 found inguinal glands in *S'. grirami. 



In an odd foot of a Sylvicaqyra closely related to the typical 

 *S'. grimmi, and given to me by Mr. Geirard (text-fig. 94, A) I 

 found pedal glands resembling in all essential points those of the 

 legs of the examples identified above .as >S'. coroitata. 



The features to be noticed in connection with the cutaneous glands 

 of the Cephalophinai ai-e the geneiul constaiicy of the sti-uctui-e of 

 the preorbital gland and of the feet and the minor diflerences pre- 

 sented 1)V each. The preor])ital gland is always large, oval, tough 

 and india-rubbery in consistency, is situated farther forwards 

 than in other Antelopes, and has no valvular invagination of the 

 skin connected with it as in Gazelles, Sheep, Dik-Diks, and others. 

 Instead of this it commiuiicates with the exterior by means of 

 a series of setiferous pores placed on a narrow sti-ip of bare 

 integument. It differs, in fact, from that of all other Ruminants. 



The structure of the feet, too, is very unifoi-m. They do not, 

 however, differ materially from those of Madoqiia, as illustrated 

 by M. phillipsii, nor from genera of Neotraginse that I have 

 examined, namely Oiirehia and 7i'aphicerus. Only in one little 

 point is there, within my expeiience, a constant difference. 

 "Whereas in the Mado(|uina' and Neotragina^ the web joining the 

 heels is covered continuously with long hairs, in the Cephalophinfe 

 the back of this area of integument is always naked foi' a longer 

 or shorter distance. 



Another peculiar feature of the Cephalophina; is the wide 

 separation of the inguinal glands, when present, from the 

 mamma?. In this particular, however, they resemble some 

 Tragela])hina:' and PavtJiolnps. 



In my opinion the absence of the inguinal glands* in the forms 



* This differpiifc, as well ns otlicrs, liotwocii mclannrhexLs and dorsalis was noted 

 on the same material by Mr. V. K. Hcddanl (P. Z. S. I'.UKI, i. )>. 181).
