SIO Careinological Fauna of India. 



The chelipeds in tha adulfc male are a little more, ia the adult 

 female a little less, thau twice the length of the carapace, but are slightly 

 shorter than the legs : they aie smooth and polished, as also are the legs. 

 The arm hxs a strong upstanding claw-like tooth near the middle of its 

 upper border, one or two spinules near the far end of the outer border, 

 and a spinule near the far end of the inner border : the wrist has both 

 the inner and tlie outer angles spiniform. 



The third pair of legs, wliich are slightly the longest of the foui% 

 are rather more than two-and-a-half times the length of the carapace. 

 In all, the anterior edge of the meropodites is armed with spines and 

 the same edge of the carpopodites with spinules — these being least 

 numerous and least distinct in the case of the first pair. 



Colours in glycerine : chelipeds aud legs rather dusky red ; cai'apace 

 dusky red behind the transverse groove — which forms a very sharply- 

 defined red band — livid red, or almost violet, in front of it ; eyestalks 

 nlmost purple, eyes purplish-black. Eggs in life magenta. 



The carapace of the largest male is 15 millim. long and 20 millim. 

 broad. 



Only known, so far, from the Andaman Sea : 2 males and a female 

 from 173 fins., 2 males and a female (Types of the species and genu.s) 

 from 1S8-220 fms , 7 females (3 with eggs) from 185 fm.s., a male and 

 4 females from 370-419 fms. 



12. Psopheticiis insignis, n. sp. 



■Carapace subquadrilateral, the antero-lateral borders being slightly 

 arched, about three-fourths as long as Inroad, smooth, crossed trans- 

 vpi-sely by two very low and indistinct ridges — one (convex forwards) 

 between tlie lateral epibranchial spines, the other at the level of the 

 post-cardiac region. The extent of the fronto-orbital border is about 

 three-fourths the greatest breadth of the cai'apace. 



There is a bluntish tooth at the outer orbital angle, and an obliquely 

 prominent spine at the junction of the antero-lateral and postero-lateral 

 borders, the edge of the carapace between the two being granular. 



Eye small, suhglobular, its diameter being hardly a tenth the 

 greatest breadth of the carapace. 



Chelipeds more than 2| times as long as the carapace and decidedly 

 longer than the legs : they are unarmed except for a small tooth or 

 spinule at tlie outer angle of the wrist. 



The meropodites of the legs have the anterior border sharply 

 granular, and in the case of the last three pair of legs there is a 

 spine near the far end of this border. The longest pair of legs are 

 hardly 2J times as long as the carapace.
