The 4th and 5th legs (roxal joint included) are only about half as long 

 as the carapace : both are subchelate and have a short broad propodite 

 and a tiny claw-like dactylus, the propodite having a pavement-like patch of 

 setose granules on its outer surface. 



In the female the appendages of the ist abdominal somite are unira- 

 mous, those of all the other somites are biramous : in the male the abdomi- 

 nal appendages 1-5 are all uniramous. 



Colour in life, dull chalky red. 



The female is 28 miliini. long, the carapace being 9 miihm. ; the male is 

 larger.

Carapace usually somewhat elongate, and somewhat broadened poste- 

 riorly and feebly calcified laterally. Rostrum sometimes fairly prominent ; 

 sometimes obsolescent and leaving the ophthalmic segment exposed. Thora- 

 cic sterna variable in breadth. 



The abdomen is generally soft and spirally coiled in adaptation to the 

 form of the cast-ofT gastropod shell which the animal generally uses as a 

 habitation : in a few abnormal forms that do not use a gastropod shell the 

 abdomen may re-acquire a secondary symmetry of a sort. 



Ophthalmic scales and antennal acicle present and often large. The 

 antennular peduncle is usually of moderate length and the flagella are usually 

 short. 



Chelipeds usually massive : they may be equal and similar, or very 

 unequal and dissimilar. The legs of the 2nd and 3rd pair are elongate : 

 those of the 4th and 5th pair are short, the 4th pair being simple, or sub- 

 cheliform, or cheliform, the 5th pair being subcheliform or cheliform.
