Stations 35, 37, 38, 57. 



Body slender, strongly calcified, gradually tapering from the 

 third to the terminal segment. Front of the cephalon but little 

 prominent, rostral spine triangulate, as long as broad, the base 

 occupies the median third of the front, the apex is slightly 

 deflexed and the margins are finely denticulated, the denticles are 

 continued beyond the base and cease at a short distance from the 

 obtuse, elevated lateral angles of the front. 



Ocular lobes well defined; an oblique ridge is present superiorly 

 and the outer distal border is obtusely rounded. 



Eyes conspicuous, with six or seven distinct, pigmented ocellte. 



Upper surface of cephalon strongly areolate, and carinate; the 

 posterior sides are tumid, evenly rounded, and exhibit numerous 

 low, reticulated ridges; one is more strongly marked, and extends 

 ol;liquely from beneath the ocular lobe to the upper lateral aspect 

 of the posterior border.
