The right cheliped is slender, and reaches the base of the left dactylus ; all 

 its joints are setose, the upper part of the hand being hidden in a mat of hair : 

 the upper border of the carpus and of the hand is serrulate, but the outer 

 surface of these joints is smooth except for a faint longitudinal broken line 

 of low elevation. 



The 2nd and 3rd legs slightly surpass the left cheliped : on both sides 

 of the body they are setose, but those of the left side are very much more 

 abundantly so than those of the right, and the setse on the posterior surface 

 of the long joints of the 3rd left leg form a dense mat as on the left hand : in 

 both pairs the dactyli are much longer than the propodites. When denuded 

 the legs are unarmed, except for a terminal spine at the far end of the anterior 

 border of the carpus. 



Length of carapace of largest specimen ig millim. 



Colours in spirit : pinkish yellow, chelipeds mottled and reticulated with 

 red and white, the legs also but less extensively and less vividly.

Body squat ; carapace not broadened posteriorly, strongly calcified except 

 in the branchial regions. Rostrum broad, not very prominent. 



Abdomen well developed, soft, simply flexed, not coiled, symmetrical. 



Eyestalks of good length, slenderish ; ophthalmic scales well separated. 

 Antennal acicle well formed ; flagellum short. 



Mouth parts as in Paguristes and Clibanarius, except that there is no 

 flagellum to the endopodite of the ist maxilla. External maxillipeds approxi- 

 mated at base. 



The chelipeds and 2nd pair of legs are profoundly modified to form an 

 operculum to the hole in which the animal lives : their three terminal joints 

 are trihedral and are set at right angles with the merus, and have their upper 

 (now anterior) face concave or canaliculate by reason of the salience of one
