In now identifying White’s species with 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 /. 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 figures 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 hable to abnormality may be judged from the figure of the 
larger cheliped in Zool. ‘Erebus’ and ‘Terror,’ Crustacea, pl. 2. 
figs. 5, 5 « (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. latimanus, and Hen- 
derson a var. jugosa. 
Mr. Vallentin obtained specimens from Macrocystis.
