In now identifying White's species Avitli that described by 

 Milne-Edwards eleven years earlier, I am bound to offer some 

 grounds for my change of opinion. As years pass on the form 

 known as E. comptus is repeatedly collected in the southern parts 

 of South America, and this form agrees well with the description 

 and figure given by Milne-Edwards for his E. forceps, with the 

 remarkable exception of the smaller cheliped. This he describes 

 and figui-es as having the palm extremely short, the fingers slender, 

 long and pointed, the movable finger almost filiform and straight, 

 or even sinuous. There is something so unusual in this character 

 of the smaller cheliped, that, as it does not appear ever to have 

 been observed again, one may be excused for regarding it as an 

 abnormality. It is not at all certain that Milne-Edwards had 

 more than one specimen, though he gives an alternative for the 

 form of the movable finger. He figures it with two slight curves 

 but base and apex in line one with the other. That the species 

 is liable to abnormality may be judged from the figure of the 

 larger cheliped in Zool. 'Erebus' and ' TeiTor,' Crustacea, pi. 2. 

 figs. 5, 5 a (1874), where the movable finger is evidently stunted. 

 The variability of the species is further shown by the fact that 

 Miers thought it necessary to name a var. lativicmus, and Hen- 

 derson a var. jugosa.
