Indian Deep-sea Dredging. 267 



fine groove which runs from the cervical without interruption 

 to the outer of the two supra-orbital fissures. A huge re- 

 curved spine arises from the middle of the cardiac boss in 

 addition to the two blunt triangular spines at the hinder 

 margin of the carapace. The chelipeds are cylindrical and 

 finely and sharply granulated ; the meropodite is but little 

 longer than the carpopodite with the palmar part of the pro- 

 podite, which last is a little inflated in its basal half and about 

 as long as the dactylopodite. The legs are not very strongly 

 granulated : their dactylopodites have the same structure as 

 in Parilia Alcocki. The abdomen, which interlocks with the 

 thorax much in the same perfect way as in the last-named 

 species, is five-jointed, the fourth, fifth, and sixth segments 

 being ankylosed together ; the seventh is acuminately trian- 

 gular. The brood-cavity communicates by holes with the 

 branchial cavity. The afferent branchial apertures are large 

 and prominent ; their carapacial border is divided by a fissure 

 into two lobes, an outer with rounded and an inner with 

 sinuous margin. 



One female specimen from Station 56, 240 to 220 fathoms. 



Length of carapace 32 millim. ; breadth of carapace between 

 last pair of lateral tubercles 33 millim. ; length of chelipeds 

 65 millim., of their meropodite 26*5 millim., of palm of pro- 

 podites 15 millim., of their dactylopodites 15 millim.
