In the female there was a distinct })ieorbital gland, marked 

 externally by a tuft of hair darker in colour and a little longer 

 than that of the surrounding area. Jieneath this the skin was 

 considerably thickened, the thickest pai-t being situated above 

 towards the anterior angle of the eye and the thinnest part lielow, 

 whei'e the thickening gradually mei-ged with the normal skin 

 of the cheek. In its essential characters this gland resembled 

 that of the Sable Antelope above described (p. KIO). 'J'lie male 

 was not examined for this charactei-. 



Jioth specimens liad two pairs of teats and a single pair of 

 inguinal glands representing the posterior pair found in Ceri'i- 

 capra redanca ; but in addition to these there was upon the right 

 side in the female a very minute pocket lying far out and in advance 

 of the mamma\ There was no trace of this on the left side. 

 Tlie orifice of the large gland was subcircular, about h fin inch 

 in diameter in the male and \ of an inch in the female ; the 

 })ouch itself was capacious, widening considerably within the 

 orilice and extending for 1 inch in the female and 1| inches in 

 the male in the direction of the scrotum and niannna'. The 

 yellow secretion had exactly the same nauseating smell as that of 

 Cervicaqyra redunca, namely of llour-paste or starch. There were 

 no pedal glands and no trace even of the duct. The structure of 

 the feet was the same as in Cervicapra redanca, Avith the same 

 elongated mass of vascular gelatinous tissue lying Ijetween the 

 penultimate phalanges along the innei' suii'ace of the skin of the 

 liack of the pastern. The skin round the false hoofs was naked.

According to Owen, A', ellijisijr/'i/iiiiucs has neither preorbilal 

 nor inguinal glands. 



It is on account of tlie alleged al)sence of the iiigtiinal glands 

 in this species and their presence in A. koh that I keep the two 

 species under separate genei'ic headings. Trouessart regai-ds 

 them as I'epresenting distinct subgenera, presumal)ly for other 

 rea.sons. 



On the skin of the head of an example of K. defassa, from the 

 White Nile, lent to nu; by Rowland Ward. Ltd., I could find no 

 trace of a preoi-bital gland : liut I llnnk a gland i'escnd)ling that 

 of Adenota koh will |ni)i.Mlily be lound when fre.sh material is 

 exainiued. Tlie fore .uid liiml Icri df A'. iiiarUe (]\[rs. Oray's 

 Walcr Buck), given to me by Mr. (leirard, showed no trace of 

 pciliil glands, the feet in .spction resembling those of A. koh.
