In the "Order Amphipoda, Family Gammaridse," White thus describes his genus Ephippijihora: — 

 " Head rather large ; antennfe distant from each other, the upper pair with the basal joints very 



thick and corneous, inserted in a deep notch in front of head ; two setaj at the end of each, 



the outer the thicker. Lower pair of the antenna with the basal joint somewhat elongated 



and furnished with hairs. 

 " Body much compressed, the lateral appendages on the first eight joints very large, and nearly 



concealing the legs ; the appendage of the fourth joint much dilated behind at the end ; 



eighth to eleventh jomts slightly keeled on the back ; appendages of the three last joints of 



abdomen longish, with short spines on the edge behind. 

 " A genus allied to Orchestia and TaUfrus." 

 "Ephippiphora Kroyeri, AVhite, List. p. 130. 

 " The body is very highly polished, the edges of the segments behind somewhat tinged witli 



yellow ; the legs and caudal appendages slightly brownish.
