1. Paramithrax Coppingeri, sp. nov. 



Carapace armed in the middle line with four spines, the first 

 two large and placed near one another on the middle of the 

 gastric region ; the remaining two small, and situated near the 

 posterior border ; between the two pairs, on the cardiac region 

 a transversely-placed pair of divergent spines, the bases of which 

 nearly meet in the middle line. Two prominent spines directed 

 upwards, backwards, and outwards on each branchial region. 

 Eostral cornua very long, slender, and slightly knobbed and 

 incurved at the extremity. Upper orbital border with three 

 straight, acute, spinous teeth, behind which are two post-orbital 

 spines separated by deep fissures from one another and from the 

 upper orbital border ; the posterior spine the larger, broad, 

 compressed, and obliquely truncate. A prominent, sometimes 

 sub-bifid tooth behind this on the border of the hepatic region. 

 Basal joint of the external antenna) with a short tooth at the 

 proximal end of its outer border, with a very prominent compressed 

 tooth directed outwards at the distal end of the same border, 

 and a third, somewhat smaller, directed downwards and forwards 

 at the inner and distal angle ; flagellum longer than the cornua 

 of the rostrum. Merus of chelipedes armed above with four 

 compressed teeth of which that situated at the distal end is very 

 prominent ; carpus with two denticulated crests. First pair of 

 ambulatory legs a little longer than the chelipeds ; all the
