Phoxus. Kroyer, Tidsk. vol. iv. p. 150, 
Generic character. Cephalon considerably produced anteriorly 
to a point, not much depressed. Superior antennse having a 
secondary appendage. Maxillipedes subpediform. Gnathopoda 
subchelate. Posterior 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 Stimp- 
son speaks of them as being two in number, but they 
are very imperfect, and generally white, and disappear 
soon after death. The superior antennae 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 shorter than any of the others. 
The last pair of caudal appendages are biram ous, and the 
terminal plate is double.
