LIII. — On some External Characters of Ruminant Ar/io- 

 dactyla. — Part I. The Cephalopliinse, Neotraginae, Oreo- 

 traginae, and Madoquinse. By R. I. Pocock, F.R.S. 



In 1910 (Proc. Zool. Soc. pp. 840-986) I described the 

 specialized cutaneous glands and some other external characters 

 of Ruminants. The account was based upon the facts re- 

 corded by previous workers, upon the post mortem examina- 

 tion of. specimens that had died in the Zoological Society's 

 Gardens and upon dried skins in the collection of the British 

 Museum or in the possession of Messrs. Rowland Ward, Ltd., 

 and of Mr. E. Gerrard, who kindly helped me with material. 

 Since that time I have had the opportunity of seeing many 

 additional specimens, some belonging to species previously 

 examined, others to species, and in some cases to genera, 

 which were not available for inspection in 1910. Most of 

 the additional specimens were fresh individuals that had been 

 exhibited in the Zoological Gardens up to the time of their 

 death, but several of them were brought to me, at my special 

 request, from British East Africa by the late Mr. F. C. Selous 

 on his return from his last hunting-trip to that country before 

 the outbreak of war. 



All this extra material has enabled me to confirm and 

 amplify my previous records, and in some cases to correct a 

 few of the statements with regard to the structure of the 

 pedal glands, which were based upon what has proved to be 

 defective material in the form of feet supplied by Messrs. 

 Rowland Ward and Gerrard. 



In a series of short papers to be published in the course of 

 the current year in the ' Annals,' I propose to embody the 

 facts noted since 1910 as supplementary to the account 

 issued in that year; and to facilitate reference I have in- 

 serted after each species or genus cited the page of my paper 

 in the ' Proceedings of the Zoological Society ' where the 

 species may be found.

I had not seen this species in 1910. It is of special in-
