706 JOHN HEWITT. 



abdomen is very similar to, but not quite identical with, that 

 of the New Zealand species. In those species, according to 

 Mr. Hogg's recent notes on piscator and judging from the 

 original figure of A. maritima, the dorsal surface presents 

 a yellow pattern on a dark background rather than dark on 

 yellow as in africanus. 



Carapace. — The ocular characters are not quite as 

 described in piscator. In the hind row, the distance 

 between each pair is distinctly greater than the diameter of 

 the posterior lateral. The area of the anterior laterals is 

 quite twice as great as that of the posterior medians, and is a 

 little larger than that of the posterior laterals. The distance 

 between anterior and posterior laterals is about two-thirds the 

 diameter of the latter. (In both the New Zealand species the 

 lateral eyes seem to be rather more widely separated from each 

 other.) At the sides and in front, the ocular area projects 

 above the general surface of the carapace ; posteriorly, how- 

 ever, along its whole width, the ocular area passes quite 

 insensibly into the general surface of the carapace. Apart 

 from the general clothing of short grey hairs, there are a few 

 scattered long black hairs on the carapace ; these latter are 

 most numerous in the ocular region. Viewed under a high 

 power of the microscope, the grey hairs are seen to be finely 

 ciliate. A long stiff hair projects upwards from between the 

 antero-median eyes. 



Labium. — This is not nearly so much constricted at the 

 base as represented in the figure of piscator. (Mr. Hogg 

 informs me that the constriction indicated in the figure of that 

 species is only a surface depression.) 



Sternum. — The anterior margin is narrow and slightly 

 curved. It is broadest opposite to the coxa? of the second 

 pair of legs. 



Chelicerse. — The lateral and upper surfaces of the basal 

 joint are rather coarsely sculptured, except towards the apex, 

 where they are smooth ; there is a very prominent basal spot 

 with smooth surface. The fang is stout and not very long ; 

 there is on the outer side a slight transverse constriction
