The second gnathopod is of the usual kind; a rather 

 short curved basis is stout compared with the succeeding 

 joints; the ischium is long and the following joints short and 

 subequal ; the dactylus is short and stout with single claw. 



The remaining legs are similar, with long ischium 

 joints rendering the succeeding ones very short; the basal 

 joints are robust and little pads are found at their distal 

 ends, as also at the ends of the three following joints ; the 

 legs are sparingly hairy with few spines. 



In the first pleopods, which are the smallest, the 

 endopod is oblong and about twice as long as broad; the 

 fringes of both rami are very long. 



The second pleopods are larger than the first, the fringes 

 are long, and the appendix is broad and exceeds the length 

 of the inner ramus. 



The third pleopods are fringed, the exopod has a division 

 not very near the end, and there is a slight insinuation on 

 the inner margin. 



The fourth pleopod is composed of two ovate thin plates 

 without fringes. 



In the fifth pleopods the exopod is nearly twice as long 

 as broad, with three lobes one above the other on the inner 

 margin, as in Chitonopsis; there is a faint indication of a 

 division near the end. 



The uropods are lamellar, rather narrow, the inner ramus 

 reaches to the end of the abdomen, the outer ramus is a small 

 plate filling a cleft in the side of the uropod. 



The female is similar to the male, except that the 

 middle lobe of the first antennular joint is absent and the 

 anterior lobe is smaller; the flagellum has 3 joints; the 

 antenna also is slenderer ; the prolongation of the epistome is 

 shorter. 



One male and one female without visible brood.
