(Vol. II. p. 18.*) 

HYPERIA TAURIFORMIS, N.S. 
Specific character. Antenne very short. Both pairs of gnathopoda with 
the proximate margins of the propodos and carpus strongly serrated, as well 
as the dactylos of the second pair. 
Length, four-twentieths of an inch. 
THe antenns in this species are very short. The inferior 
angle of the carpus is anteriorly produced in both pairs of 
gnathopoda, and the proximal margins of the propodos and 
carpus are strongly serrated, as also is the dactylos of the 
second pair. 
Dana established the genus Tuuria for the reception of 
those species of Hyperia that have the antero-inferior angle 
of the carpus of both pairs of gnathopoda so far anteriorly 
produced as to extend to the extremity of the propodos, thus 
forming a tolerably perfect but compound chelate organ. 
But so gradual is the development of this process from one 
species to another, that we can see no clearly defined limit 
where one genus may commence and the other end. 
We have chosen a specific name for our new species which 
indicates its affinity with Dana’s proposed genus. 
The animal above described was taken at Banff by Mr. 
Edward.
