Genus—GOSSEA. 
Gossea. Spence Bate, Cat. Amph. Brit. Mus. p. 159. 
Generic character. Superior antennae without a secondary 
appendage. Gnathopoda subchelate ; first pair the larger. 
Pleopoda long, nearly of equal length ; posterior pair biramous. 
Telson single, squamiform. 
The body of the animal in this genus is slender and 
compressed. The superior antennae are not furnished 
with a secondary appendage, and the peduncles of both 
pairs are shorter than their respective flagella. The first 
pair of legs are furnished with hands larger than those of 
the second, and both pairs are subchelate. The posterior 
pair of caudal appendages are double-branched and reach 
considerably beyond the extremity of the central caudal 
plate which consists of a single scale. 
The animals of this genus bear a near resemblance to 
those of Microdeutopus in their general aspect, but differ 
from them in the absence of the secondary appendage to 
the superior antennae, and in the form of the telson. 
To the genus Dry ope they approach nearer; but the 
more compressed form of the body and greater length of 
the caudal appendages sufficiently separate the two 
genera. 
The genus has been named in compliment to Mr. 
Gosse, whose numerous contributions to Marine Zoology 
have greatly tended to popularize many obscure pro- 
ductions of nature.
