Of this gioiip Owen recortls the presence of pieoi-bit.il j^'l.mds 

 :ui(l the nhsenee of in^^uinal glands in the follo\vin;jf species: — • 

 DamaliscKs luiKiins, Bubal la hoselajtinis {=■ Jntilupe hiffjulis), 

 B. caaina, Uoryoii taurinns, and Cotiiificha'tes ynu. 



Ogilby, who examined Jiuhali-i honclaphiis, which he (piotes as 

 B. luauretanicas, confirms Owen's statement regarding the above- 

 given particulars, adding that the ))edal glands are large and that 

 there is a single pair of mamma'. 



Recent systematic wiiters agree with Ogilby as to the number 

 of mamniie ; but in spite of his u.se of the epithets ^^exiyai, 

 dixiincti" in describing the preorl)ital glands, these are quite 

 commonly, but erroneously, stated to Ije small. 



Of Hartebeests belonging to the genus Babalis I have seen 

 no complete material, and have been com})el!ed to rely upon 

 soaked feet and niiisks usually with the skin only of the in'corbital 

 gland retained. Of the White-tailed (luu {Coimochades ijnii) I 

 have seen two fre.shly dead specimens, i have, however, seen 

 living examples of the two species of (inu (6'. tctKrimi-n, ('. ynu) 

 and of two species of Davudiscas {/). y//.'/'"'.'/'' '"'"^ ^^- (tlbifrons,

I am in<lebted to Mr. E. Oerrard for a ma.sk, cont:iining 

 entire preorbitid glands, and front and hind feet of this species. 



The preorbital gland.s Avere covered with hairs which in the 

 individual examined had a thickened appearance, owing to the 

 coating of brown earthy-looking secretion which covered them 

 individually. The centi'c of the area, wns marked by a, distinct 

 orifice leading into a narrow duct about half an incli long and 

 lined with short hair. This duct penetrated alniut halfway into 

 the lai-ge gland which was about as large as a walnut. 



Pedfd glands were present only on the fore feet, or if jiresent on 

 the hind feet they attained only a c-omparativeiy slight degree of 

 development. On the fore feet they xevy closely resembled those 

 of (iazelles, consisting of a very large interdigital cavity opening 

 by a long orifice on the anterior aspect of the })astern and 

 extending upwards lioin the ])roximal margi)i of the hoof in 

 front. As in Gazelles the tw») hoofs were united by a deep 

 interungual web, which extended from the heels to the proximal 

 margin of the hoof in front, then folded .sharply over and was 

 <-ontin»ied backwards along its cour.se nearly as far up as the 

 fal.se hoofs, where it turned oblicpiely forwards ami downwards, 

 meeting the skin of the front of the pa.stein at an acute angle to
