about equal to, the palm : the carpus has the inner edge spinose, and has a 

 median longitudinal row of granules or blunt spinules on its outer surface : 

 both edges of the palm (and the corresponding edges of the fingers) are 

 spinose, and the outer surface of the palm is studded with blunt, curved 

 spines, one series of which forms a close-set median longitudinal row extend- 

 ing to the tip of the fixed finger: the finger-tips are corneous. 



The 2nd and 3rd pairs of legs surpass the chelipeds ; the anterior border 

 of the carpus and propodite is distantly serrulate ; the dactylus is about as 

 long as the two preceding joints combined. 



The right vas deferens is long, and ends in a long lax curling filament, 

 the left is short and papilliform. 



The paired appendages of the first segment of the female abdomen are 

 slender, curved rods, closely embracing the thoracic sternum. 



Length of carapace of male about 7 miltim., a female with eggs is smaller. 



One specimen inhabits a shell that is embedded and hidden in a large 

 colony of Epizoanthiis,

4. Nematopagurus scutellichelis, n. sp. Plate XII., fig. 3. 



Gastric region nude. Rostrum broad, rounded, obsolescent, not so 

 prominent as the antennal angles of the carapace, and leaving the ophthal- 

 mic segment exposed. 



Eyestalks piriform, not so long as the front border of the carapace, reach- 

 ing a little beyond the middle of the terminal joint of the antennal peduncle. 

 Eyes reniform. Ophthalmic scales distant, small, papilliform, with a tiny 

 subterminal spinule inferiorly. 



Upper antennular flagellum about as long as the terminal joint of its 

 pduncle, The antennal peduncle is shorter than that of the antennules : 

 acicle curved, not reaching the end of the eye : flagellum long, nude. 



Chelipeds subequal and similar, but the right wrist and hand are more 

 massive than the left ; they are a little more than twice the length of the cara- 

 pace and, like the legs, are almost nude on the extensor surface : the carpus 

 is as long as the merus and longer than the palm, the palm is longer than 

 broad, and the fingers of the right hand are a little shorter than, while those 

 of the left are about the same length as, the palm : the merus has i or 2
