the middle two are distinctly larger than the others. The middle 

 four are all rather elongated, and siibaciite. The posterior lateral 

 tooth is stout, rather eurved forward. The others are all nearly 

 equal in size, acute. The meius of the chelipeds has live stout, 

 rather close anterior teeth* ami a large posterior distal one, accord- 

 ing to Edwards' figure. The maims ha- a single distal tooth on a 

 strong carina, at the distal fourth. This species, in respect to its 

 areolation, lateral teeth, and six frontal teeth, is similar to .1. >'/////////, 

 but in the latter the frontal teeth are blunt and the middle ones are 

 less prominent; it also differs in having the merus of outer maxil 

 lipeds more prolonged. The chelipede are shorter and stouter, the 

 merus particularly so; its lar^e posterior distal tooth seems t<, lie di-- 

 tinctive. Personally I have seen no specimen- agreeing well with 

 Edwards' figure and description of 1879.

to the Chilian species. In that case the Atlantic species should take the name, 

 A. Sniithii, unless there be an earlier one. None of the early writers, before 

 A. M.-Edw. have given a figtire of either form, so far as I know. 



* Miss Kathtran, 1901, gives, in her description, only four, as in Gibbeaii. In 

 our No. 829, there are four on one side and five on the other.
