Mr. Sedgwick described specimens in which the dorsal surface 

 and most of its papillae are reddish brown, but I have not met with 

 such cases. The same author states that the colour appears to be 

 hardly at all affected by spirits. This is scarcely correct, for the 

 red of the ventral surface may disappear after a few weeks, and 

 although that of the dorsal papillae may remain for some years, it 

 also ultimately entirely disappears, while the black pigment becomes 

 dark green. 



Locality. P. capensis is widely distributed over the Cape 

 Peninsula. It has been found under stones in ravines on the 

 mountain-side at St. James (False Bay), and in similar places on the 

 Cape Town side of Table Mountain (near Platteklip). It is found 

 throughout the woods at Newlands, Rondebosch, Wynberg, and 

 Constantia, often in hiding in rotten tree-stumps. It is not con- 

 fined to the mountain slopes, but occurs in the low-lying land as 

 well.

The original diagnosis was very brief, as follows : "P. inoscleyi, 

 with 21-22 pairs of walking legs, from South Africa." * Professor 

 Sedgwick subsequently obtained and described in detail one of 

 Wood-Mason's specimens, together with four others in the 

 possession of the Indian Museum, the locality of which is stated to 

 be "near Y/illiam's Town, South Africa." Sedgwick states that 

 W T ood-Mason's specimen was found by Mr. J. P. Mansel Weale, 

 but no locality is given. As Mr. Weale is known to have collected 

 many natural history specimens from the King William's Town and 

 East London Divisions in the Cape Colony,! I think it highly 

 probable that the type-specimens of this form were also found by 

 him somewhere in these two districts. 



* Were it not for Sedgwick's subsequent description P. moscleyi would have 

 remained quite unrecognisable. A diagnosis based on the number of legs alone 

 without the exact locality is totally insufficient.
