A small species allied to C. alba Holmes in not having a groove on the 

 under side of the sixth abdominal segment. 



Carapace a third as long as the abdomen ; rostrum narrow-triangular, 

 short, with a rounded tip. Antennulae as in C. alba. Antennae nearly as 

 long as the body ; scale either as long or nearly as 

 long as the carapace exclusive of the rostrum; 

 e blade very narrow at the extremity; spine much 

 exceeding it. Maxillipeds exceeding the scale a 

 little; antepenult segment not dilated. The first 

 st P ai ' r of feet reach to the Diddle of the terminal 



^ f the maxilli P eds \ thfi hand elongate, about 



j.Acicie(X4). <--.cheia(x8). tm - ee times as long as wide; the anterior margin, 

 against which the dactylus folds, is more longitudinal than transverse. 

 The third pair of legs is a very little longer than the second ; they are 

 equally slender. The segments of the abdomen are smoothly rounded 

 above ; the sixth without a ventral sulcus ; the seventh is a little longer 

 than the sixth, or about as long as the antennal scale, and is exceeded by 

 the uropods.

 5.3 mm., of antennal scale 4.2 mm.
