Delia Valle unites this with A. Eschrichti, but I find not 

 the slightest difficulty in distinguishing thera. The pro- 

 nounced character of the tooth of the anterior epimera is one 

 well-marked distinction ; and under the microscope it is seen 

 that the propodos of the penultimate perseopod has not the 

 lobe projecting beyond the base of the nail, which is so dis- 

 tinctive a mark in A. Eschrichti (see Sars, /. c. pi. Ixi. fig. 1, 

 p.^) ; and the carpus of the last perfeopod is quite -different 

 in form and spination. In A. Eschrichti the front side of this 

 carpus is furnished with a little lobe bearing two spines, 

 while in A. odontoplax^ though there are two spines, there is 

 no lobe. This may seem a trifle, but when familiar with 

 species it is generally by some microscopic " trifle " on a part 

 easily seen that I am in the habit of identifying thera ; and 

 the structure of the carpus of the last perseopods in this 

 species at once separates it from all known allies.
