 this species also was found on rocks. 



Some months ago I submitted immature examples from 

 East London to Mr. H. R. Hogg, who very kindly compared 

 them with the types of pi sea tor, afterwards reporting that he 

 was unable to find any essential difference in structure between 

 the South African and New Zealand specimens. Apparently, 

 therefore, the only satisfactory basis of distinction between 

 a f r i c a n u s and p i s c a t o r is that which may possibly be offered 

 by the external sexual characters. The males of the New 

 Zealand species have not been described in either case, and 

 the epigynal character of the adult female of A. piscator, as 

 figured by Mr. Hogg, appears to be quite distinct from that 

 •of af ricanus, the characters of which are constant in the 

 series of six or seven adult specimens now at my disposnl. 



Colour. — Cai-apace brown, becoming black-brown on the 

 ocular area. Clielicera3 black-brown throughout, except in 

 the terminal half of the fang, which is reddish. Lip and 

 maxilla3 reddish-brown. Legs and sternum pale brown. 

 Upper surface of abdomen yellow, with a median dark tree 

 pattern constituted by a series of six dark transverse chevrons, 

 the three anterior ones being connected together by a median 

 stripe which extends considerably in advance of the most 

 anterior chevron. The anterior chevron is much broader than 

 any of the succeeding ones, and the second is broader than 

 the third, though not quite so long. Towards the posterior 

 end of the abdomen, tlie colour is dark throughout except for 

 faint indications of yellow stripes. The latei'al surfaces of 

 the abdomen are dark with three yellow, backwardly directed, 

 oblique stripes. These stripes superiorly pass into the yellow 

 of the dorsal surface, but inferioi'ly the two posterior ones 

 taper finely and end blindly near the posterior end of the 

 abdomen, whilst the anterior one is quite short and broad, not 

 extending far towards the ventral surface. The ventral surface 

 of the abdomen is pale, the dark coloration of the sides 

 gradually merging therewith.
