STALK-EYED CRUSTACEA. 



the first to the last one. The upper margin of the orhit is thickened and 

 produced into a blunt prasocular tooth. The outer margin of the pterygo- 

 stomian region is furnished with two or three rounded tubercles. The merus 

 of the chelipeds has two short spines at the proximal end on the superior 

 border and one at the distal extremity ; otherwise the limbs are unarmed ; 

 the fingers of the chela are short; gape slightly at the base^ and have blunt 

 tips ; no teeth on cutting edges. 



Length of carapace, including rostrum, 39 mm. ; length of rostrum, 16 

 mm. ; breadth of carapace, including lateral teeth, 28 mm. 

 v^Station 3368. 66 fathoms. 1 male. 



Sphenocarcimis corrosiis A. M. Edw., the type of this genus, was taken near 

 the Barbadoes in 100 fathoms during the voyage of the " Hassler," and near 

 the same locality in 94 fathoms by the " Blake." The two specimens secured 

 are females. In S, agassizi there is a blunt pr^eocular tooth, wanting in the 

 typical species. The ends of the rostral horns do not lie in exactly the 

 same plane in the single example before me, but this is probably due to 

 accidental malformation. The abdomen (male) is seven-jointed. In both 

 species there is a narrow fissure in the upper margin of the orbit, just 

 anterior to the postocular tooth. 



Sphenocarcimis agassizi was also obtained by the " Albatross" in 1889, in 

 the Gulf of California, at depths of 14 and 71 fathoms.

Carapace piriform, strongly arched when viewed in profdc, its surface 

 clothed with tuberculiform cutaneous vesicles* and with delicate seta) which 

 are hooked at their tips. The spines and tubercles of the carapace are 

 arranged as follows : four on the gastric region, two of which are in the 



w 



median line and one on each side; the posterior median has the form of a 

 blunt tubercle, from which a blunt low keel runs back to the cardiac region ;
