smooth. Third joint of the peduncle of the superior antennae half 

 shorter than the second; fourth (? fifth) joint of the peduncle 

 of the inferior antenna; much longer than the third. 

 " Length 8-9 lines.

2. (Edicerus Novse-Zealandiae. (Plate XVII. fig. 1.) 

 CEdicerus Novi-Zealaudiai, Dana, U. S. Explor. Exped. p. 934. pi. 63. f. 7. 



" Superior antennae not half as long as the body, terete. Inferior 

 pair nearly twice as long ; base twice as long as base of superior ; 

 flagellum about 21-jointed, tAvice as long as base ; setae very short. 

 Fifth pair of pereiopoda as long as body, styliform at extremity. 

 Gnathopoda unequal, similar ; propodos of fii-st pair smallest ; of 

 second pair of moderate size, broad subovate, nearly naked, obliquely 

 truncate ; palm oblique, very slightly excavate, or nearly straight. 

 Three posterior pairs of pereiopoda having the bases rather narrow. 



" Length 2 lines. 



" Hah. Bay of Islands, New Zealand, in small pools on the rocky 

 shores near Cororatika. Collected March 1840." — Dana. 



The figure of this species does not exhibit the generic character of 

 the anteriorly produced cephalon ; but in all other resj)ects it agrees, 

 except perhaps the eyes. Grayia Pugcttensls may belong to this 

 genus (certainly not to Iphimedia) ; my only doubt rests upon the 

 length of the fifth pair of pereiopoda.

Cephalon produced and depressed anteriorly. Eyes coalesced into 

 one, situated above and anterior to the superior antennae. Su- 

 perior antennae not appendiculated. Gnathopoda subchelatOj 

 haATing the carpus produced along the inferior margin of the 

 propodos, so as to meet the apex of the dactylos. Posterior pair 

 of pereiopoda much longer than the others. Posterior pair of 

 pleopoda biramous. Telson squamiform, entire.
