Genus— PHOXUS. Kroyer. 



Phoxus. Kroyek, Tidsk. vol. iv. p. 150, 



Generic character. Ceplialon considerably produced anteriorly 

 to a point, not much depressed. Superior antennae having a 

 secondary appendage. Maxillipedes subpediform. Gnathopoda 

 subchelate. Postei'ior pair of pereiopoda shorter than the 

 others. Telson double. 



This genus may be taken as the type of the sub- 

 family. It has the head considerably advanced in front, 

 and produced into a blunt point, but which is not much 

 depressed. We have not observed the eyes, but Stim^i- 

 son speaks of them as being two in number, but they 

 are very imperfect, and generally white, and disappear 

 soon after death. The superior antennee carry a se- 

 condary appendage, which is generally very long. The 

 mandibles are furnished with an appendage. The foot- 

 jaws have the squamiform plates but little developed; 

 thus bearing a considerable resemblance to the ordinary 

 walking legs. The hands are subchelate, and nearly of 

 the same size. The last pair of walking feet are very 

 short, being considerably sliorter than any of the others. 

 The last pair of caudal appendages are biramous^ and the 

 terminal plate is double.
