at Stockholm), and several specimens of the larger kind. I have ex- 

 amined with care a series consisting of four males and five females 

 from different parts of South Africa, and can find no distinction be- 

 tween them, except a slight difference in the length of the fur and in 

 its colour. Two specimens in the British Museum are larger than 

 the rest, and have the tarsus one-fourth longer than the others ; they 

 have a shorter fur and are of a rather brighter colour, and the front 

 of the leg is blacker ; but the fur and colour probably depend on the 

 season when they were killed. In these respects they agree with 

 SundevalPs description of A. Isabellina, but they both have the tem- 

 poral spot large and quite naked, while Prof. Sundevall described the 

 spot on this species as pubescent. The female of the larger specimen 

 has the black spot on the back of the head ; some of the smaller 

 ones have the temple-spot much smaller and less naked than the 

 others. The two larger specimens have a single whorl of hair in the 

 middle of the back ; the others, with longer hair, show the whorls 

 more distinctly, and have the hair from the central whorls to the 

 shoulders forming a more or less diverging line. After examining 

 these specimens and those in other collections, I conclude that they 

 form only a single species. M. Sundevall, in a note just received, 

 observes, " Mr. Wahlberg considers A. Isabellina and A. Eleotragus 

 as very distinct, and our specimens seem to show a difference, though 

 not very well expressed. Also I have committed a mistake, for the 

 young female described in my Synopsis as y. under A. Isabellina, is 

 really A. Eleotragus."

Pallas and Afzelius' s account of this species is derived from Buf- 

 fon's description ; both he and Adanson (Hist. Nat. xii. 326) say that 

 it is "all pale red," and Buffon further observes that it has not the
