374 Messrs. H. C. Robinson and C. Boden Kloss on 



the specimens recorded above have been included under one 

 specific name. They all agree in the possession of the 

 peculiar hook-like organs on the dorsal surface of the prosoma 

 — a character which differentiates them from all the other 

 species I have seen — but they differ greatly among themselves 

 in the characters of the capitular valves. As an example of 

 the variation in these characters, I figure a specimen from off 

 the coast of Cuba (text-fig. 7). It will be seen that it differs 

 from the holotype (from the Victoria— Tasmanian cables) in 

 the much narrower form of the capitulum, the relatively 

 shorter carina, and the scutum with the basal margin at 

 right angles to the chord of the occludent margin. Other 

 specimens, however, both from the Atlantic and from the 

 Indo-Pacific areas, are intermediate between the two forms, 

 and I am unable to point out any characters by which they 

 can be satisfactorily grouped.
