{Vol. n.p. 18.*) 



HYPERIA TAURIFORMIS, N.S. 



Specific character. Antennoe 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 antennte 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 Taur'ia for the reception of 

 those species of Hyperia that have the antero-inferior angle 

 of the cai'pus 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.
