 only a short distance, then nielininijf obliquely upwai-ds, fonning 

 the back wall of the depression in (piestioii. This depression on 

 the hind foot might be compared to the depifssion on the pastern 

 of the Chamois, except that its walls were hairy instead of nearly 

 smooth. 



Of the genus Babali.^ I have also examined the face-skin and 

 part of the gland of Ji. cokei sui)plied to me by Rowland 

 Ward, Ltd.. and by Mr. E. Gerraril. In this species the pre- 

 orbital gland has essentially the same structure as in Ji. caama. 



The following species also have tlie gland clothed externally 

 with a mat or tuft of hairs, namely, Ji. major, tora, sivaynei, 

 lelvfj, and jacksoni. In Ji. lichteusteini, on the contraiy, the 

 glandular area is naked as in JJamaliscus, the orilice in the dry 

 skin being a small slit-like ajierture leading into a duct. Tlie 

 hind foot of /i. lic/Ueiistcini is like that of Ji. caama, having only 

 a shallow depression on the front of the pastei-n. For the 

 material of the species, enabling me to establish these data. I 

 am indebted to Mr. E. (Jeiiai'(l.

1 am indel)ted to Mr. E. (lerraid for the o{)p()rtuiiity of 

 examining a c()m[)lete skin of this Jlartebeest. 



The pi'eorbitnl gland itself was cut away, but the orifice was 

 repi'esenteil by a short elongated aperture in the middle of a b.-ire 

 patch of skin in front of the eye. 



The pedal glands, present only on the front feet, resembled 

 those of Jinhalis caama in a general way, with the exception that 

 the interdigital pit was much less deep, owing to there being a 

 considerable space between the integument of the back of tlie 

 pastern and that forming the posterior wall of the cleft ; more- 

 over, the skin of the front of the pastern, forming the upper edge 

 of the oritice, was not folded backwards and npwaids upon itself, 

 but descended almost at right angles to form the short upper wall 

 of the interdigital cleft. A further difference was seen in the 

 jiresence of a vertical fascia joining the skin of the biick of the 

 jiastern to that of the interdigital cleft just above the heels. The 

 w;ills of the cleft were clothed with long rusty-red hairs, the ends 

 of which projected from the orifice, overhanging the proximal 

 end of the hoof in front. 



The hind foot was like that of Ji. caama, except that the 

 depression on the front of the pastern just above the hoof was 

 shallower. A connecting fascia, corresponding to that of the hind 

 foot, was also present. 



The area of the preorbital gland on a face-skin of D. Icorr'igmn 

 iiang, for which I am indebted to Rowland Ward, Ltd., resembled 

 that of J), k. jimela in all respects.
