This species by its smooth, compressed, and not dentate body 
is strikingly distinguished from Bovallia regis, which in many 
other points it nearly resembles. 
The specimen which I am here assigning to Chevreux’s species 
agrees admirably in most respects with the French author’s 
figures and description, especially with the figures which he has 
recently given of the male gnathopods. Of these, the first are 
larger than the second, the hands in both pairs oval, with the 
palm scarcely distinguished from the hind margin except by 
the extent of the respective fingers. The unarmed telson, with 
short division between the rounded apical lobes, is also in pre- 
cise agreement. ‘The inner plate, however, of the first maxille 
has only three terminal sete, instead of the four shown in 
Chevreux’s figure and five mentioned in his text. Also the third 
uropods have few spines instead of many, and the flagellum of 
the first antenne after the first two joints has the filament- 
bearing joints separated from two to two, not three to three. 
These differences may well be attributed to an earlier stage in 
the development, but if so, the last of them would throw doubt 
on the importance which has been attributed to these intervals 
in the flagellum of various specimens. In Dana’s /phimedia 
simplex (from Hermite Island), which evidently belongs to this 
family, the first two filament-bearing joints are the third and 
sixth, but the following are the eleventh, sixteenth, and so on for 
each successive fifth joint.
