XXXiy, — Notes on Clnysochloris Trevelyani. By Dr. 

 Albert Gunther, F.R.S., Keeper of the Zoological 

 Department, British Museum. 



[Plate XX. figs. A & B.] 



In the '■ Proceedings of the Zoological Society' for 1875, p. 311, 

 I described and figured a large species of Golden Mole from 

 British Caflfraria ( Chrysocliloris Trevelyani) from a single flat 

 skin. As the discoverer, Mr. Herbert Trevelyan, shortly 

 afterwards returned to South Africa, I begged him to obtain 

 more and better-preserved examples, entire if possible, or to 

 procm'e at least the skull. In this he was so far successful as 

 to send home flat skins of two adult and one younger spe- 

 cimen, and three skulls, one of which is in a fragmentary con- 

 dition. The skins of these examples differ from the typical 

 specimen in the fur being of a greyish brown colour, with 

 scarcely any gloss on it, the under-fur being grey. This dif- 

 ference in the colour is probably due to the season of the year 

 at which the specimens were obtained, those sent last having 

 been killed in the course of the summer. 



The skull represents one of the most singular forms in the 

 division of Insectivorous mammals ; and although its most 

 prominent and characteristic features are indicated in the other 

 species of Chrysocliloris ., it differs widely from their skulls as 

 regards general form*. From the occipital crest forwards the 

 skull is nearly equally narrow and elongate, the occipital 

 region behind that crest being abruptly truncated, vertical — yet 



* For comparison of the descriptive detail I refer to Prof. Mivart's 

 excellent account of the skull of Chrysochloris, in ' Journal of Anatomy and 

 Physiology,' ii. pp. 130 et seqq.
