96 On Three neio Forms o/Tragelaphus. 



lip and chin white ; white patches at upper and lower ends of 

 throat small, tlie former only just traceable. General colour 

 of body dark yellowish brown above, paler below, and gradu- 

 ally passing- into yellowish fawn upon the shoulder and upon 

 the lower half of the hind-quarters. No traces of white stripes 

 or spots observable eitiier upon the body or upon the hind- or 

 fore- quarters. Fore legs both outside and inside right up to 

 the base yellowisii brown, blackish all down the front from 

 above the knees to the fetlocks ; fetlocks and pasterns black, 

 except for a pair of white spots on the pasterns in front. Hind 

 legs coloured like fore legs, but paler above the hock and 

 marked with a distinct white patch in front of the hock. 

 Tail white below, dark at the tip. A collar of short hairs 

 round the base of the neck. No long crest of hairs along 

 spine. 



Nab. Sayer, in Somaliland. 



A single subadult example of this species, remarkable for 

 the absence of white on the inner side of the legs and on the 

 body, was procured by Lord Delamere on his last sporting 

 expedition into Somaliland, and kindly presented by him to 

 the British Museum. 



It is a matter for regret that there is some doubt as to the 

 sex of this specimen. In spite of the absence of horns it was 

 declared to be a male by the skinner entrusted with the 

 stripping and preservation of the skin ; but it must be held 

 to be in the highest degree improbable that there exists a 

 species of TrageJaphus with the male normally hornless. 

 Hence, unless there has been some error either of memory or 

 observation on the part of the skinner, the specimen under 

 discussion is abnormal, and its peculiarities may possibly be 

 attributable to this circumstance. This, however, is not likely 

 to be so, for in a case of this kind the characters liable to be 

 affected by falling under the influence of the cause that has 

 brought about the suppression of the horns would be those 

 which, like the liorns themselves, are of a sexual nature; 

 and the coloration of the inner side of the legs does not fall 

 into this category in the antelopes of the genus Tragelaphus. 

 Hence, whether the skin in question be that of a normal female 

 or an abnormal male, I venture to think the characters that 

 have led me to regard it as the representative of an un- 

 described species will be found to hold good when further 

 material has been procured.
