In any case it is probably only a variety of Homola larbaia witli 3 good 

 f<peciinens of wliicb — representing both sexes — it lias been compared. The only 

 differences between it and H. harhata are the following: — 



The eyes are more reniform. The second spine of the lateral border is just 

 behind the hepatic region. There are spines on the posterior border of the 

 meropodites of all four pairs of walking legs. 



Carapace elongate-subquadrilateral, its greatest breadth is across the middle 

 of the gastric region, behind which point its sides are quite straight and vertical : 

 it is well calcified, and, like all other parts except the antennary flagella, is 

 covered with short soft but stiff hairs that are not thick set enough to form a 

 coat of concealment. 



Rostrum a depressed grooved tooth, bifid at tip. Four spines on the anterior 

 border of the carapace, namely, one on either side of the rostrum, one at either 

 supra-orbital angle. 



Lateral borders of dorsum of carapace straight, very slightly convergent, 

 spinate ; the first spine, which stands alone on the hepatic region, is of pre- 

 eminent size, the second though much smaller than the first is much larger than 

 any of the others. 



Gastric region very well demarcated, armed with nine large spines — three 

 in a triangle on either median area, one on either lateral area, and one on the 

 hinder part of the central area. 



Some spines on the subocular, subhepatic, and pterygostomian regions- 

 largest on the subocular region, where they are definitely arranged in two cres- 

 centic rows. Two spines, one beside the other, on the carapace outside the 

 antenna-peduncle, in addition to the spinuliform suborbital angle. 



Eyes somewhat reniform. 



Chelipeds slender, but distinctly stouter than the legs, more hairy than the 

 carapace, especially along the edges of the joints. Upper and lower borders of 

 arm spiny ; wrist with rows of spines on the outer surface and a spine or two 

 at the inner angle ; lower border of hand spiny, upper border of hand denti- 

 culate, cutting edges of fingers sharp, entire. 



Legs compressed, their edges plumed with short bristles, with long bristles 

 interspersed. The second and third pair, which are a dactyl-length longer than 

 the first, are not quite 2^ times the length of the carapace : in all three pairs 

 both edges of the merus are armed with stout spines — at least in the distal half, 

 and the posterior border of the propus and dactylus ■^\ath compressed articulated 

 spines which are distant and acicular on the propus but stout very regular and 

 close-set on the dactylus.
