methods of research and difficulties of the literature. 

 He has collected all the information obtainable from 

 the examination of specimens and from books for the 

 discrimination of the three then known species, and 

 their geographical distribution, and gives an excellent 

 woodcut of the horns of each, and a coloured plate, from 

 a drawing by Wolf, of T. euryceros. A characteristic 

 personal reference near the beginning of the paper is of 

 interest. After mentioning that Mr. Sclater, who had 

 described Speke's Antelope from very imperfect materials 

 as long ago as 1864, had "subsequently collected some 

 MS. notes on the subject, which he intended to form 

 into a supplementary paper, more fully describing 

 the species and its allied forms," he adds : " These 

 notes, however, he has lately in the most generous 

 manner placed in my hands for consideration, knowing 

 my special interest in this branch of zoology."
