276 GAMMARIDJE. 



AMP HIP ODA . GA MM A RIDES. 



NATATOEJA. 



Genus GOSSEA. 



Gossea. SPKNCE 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, squaraiforra. 



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.
