the latter a slate. In the region of the eyes the brown tips are very 
slightly marked, so that the whole ocular region may be described as 
creamy-yellow. 
In general size G. namaquensis is a little smaller than G. asiatica, the 
present specimen measuring in greatest length 100 mm., and the hind foot 
10 mm. 
The claws of the front foot measure: 1st, 2-5; 2nd, 5; 3rd, 10*5; and 
4th, 1 mm. 
The skull in greatest length measures 21*8 mm. ; in greatest width 
16-2 mm. ; and in greatest height 11 mm. The orbital region measures 
6'4 across. The dental series measures 9 and 8*5, the molar series 5. 
The palatal width is 7*6 mm. 
Though the temporal bulla is well formed, it is considerably smaller 
than in G. asiatica. 
The upper teeth on the whole are fairly like those of C. asiatica. The 
1st incisors are large and of the ordinary type, and the 2nd incisor is also 
of the type seen in the better-known species. The 3rd incisor is very 
small, having less than half the antero-posterior length of the 2nd incisor 
and only about half its height. It is a small, rounded, simple cone with no 
ridges or cusps. The canine is nearly as large as the 2nd incisor, and has 
a sharp posterior edge, giving the top a triangular appearance, which 
suggests the beginning of the molariform type of G. obtusirostris. The 
1st premolar represents only a further development of the condition seen 
in the canine, and shows a triangular crown with no trace of the internal 
cusp seen in G. villosa. The 2nd and 3rd premolars and the 1st and 2nd 
true molars are of the well-known type with small but well-marked 
internal cusps or protocones. The 3rd molar is the most remarkable 
feature of the skull, as it is apparently absent or present in about equal 
frequency. When present it is rudimentary and has only a single small 
median cusp. 
The lower teeth are also much like those of G. asiatica. The 
premolars and molars have completely lost the talonids with the excep- 
tion of the 2nd premolar, where there is a slight rudimentary projection 
which represents it. The 3rd molar, though small, is quite well 
formed. 
By Thomas and others all those Golden Moles which have only 36 
teeth are placed in the distinct genus Amhlysomus. In my recent paper 
1 have argued that the difference between such a species as G. hottentota, 
which has lost the last molar, and G. sclateri, in which it is rudimentary, 
is so very little that it seemed to me unwise to place the forms with only 
2 molars in a different genus. The condition of the last molar in G. nama- 
quensis further confirms the view I expressed. Out of 7 skulls which I 
have examined 3 have 10 teeth on both sides, 2 have 9 teeth on both sides,
