Chrysochloeis tenuis, Broom. 



This, the third of the species met with at Garies, differs from the 

 others in having only 36 teeth, and thus belonging to the group 

 placed by Thomas in the genus Amhlysomus. As I have come to 

 consider that this is an unnatural genus, and that if Chrysochloris 

 has to be subdivided it will have to be on other grounds than the 

 number of teeth, I prefer to retain all the species in the old genus. 



Unfortunately neither of the two known skulls are perfect, but 

 they are sufficiently well preserved to show that they are quite 

 unlike any previously known forms. 



The following are the principal measurements of the skulls : —

From all the three preceding species G. tenuis differs in having 

 lost the last molar. From all the species usually placed under the 

 genus or sub-genus Amhlysomus it differs in having a fairly well- 

 developed temporal bulla not unlike that of G. namaquensis. 



The third incisor is smaller than the others, but still fairly well 

 developed. The first premolar has a large cusp, as in G. namaquensis. 

 The second molar is small, but not rudimentary. 



The only known specimens were obtained at Garies, Namaqualand. 



The type skull has been placed in the South African Museum, and 

 the other skull presented to the British Museum. 



Chrysochloris sclateri, Broom. 



This new species was founded on two specimens in the South 

 African Museum, both from Beaufort West. Like the four pre- 

 viously discussed species, it is a small form, but very unlike them, 

 and resembling in many ways G. hottentota and its allies, but 

 differing from these latter in having 40 teeth. 



The nose pad measures 9 mm. in width and 4*6 mm. in length, 

 and differs from that of G. asiatica in not having the corners pro- 

 duced into a sharp point. From G. hottentota it differs in having 

 the posterior portion much less developed. 



The fur is rather short, and coarser than in most species. On the 

 back it measures 10 mm., and on the sides 12 mm. The dorsal and 

 lateral hairs are grey in the inner two-thirds and bright reddish 

 brown in distal third, so that the general colour of the back and 

 sides is reddish brown. On the abdomen the general colour is light
