mouth. Teeth of lower jaw oblique, with the point more or less directed 

 outward. Upper teeth lanceolate, on a quadrangular base, with a sin- 

 gle cusp. Spiracles wide, behind the eye. ^rill openings narrow, (ni-vrpov, 

 spine ; aKi'pvos, an ancient name of some shark, from OKV/UVOC, a lion's 

 whelp.) 



73. CENTROSCYMNUS CCELOLEPIS, Bocage & Capello. 



Labial groove prolonged forward, but separated by a broad space from 

 that of the other side. Upper teeth very small, narrow, and lanceolate. 

 Distance between the nostrils rather less than i the length of the praeoral 

 portion of the snout. Lower angle of the pectoral rounded, not produced. 

 Dorsal fins short, especially the first, the length of which (without the 

 spine) is only about its distance from the second; extremity of the ven- 

 trals below the end of the second dorsal. Scales on the head and nape 

 with striae, the others smooth, with a depression at the base. Uniform 

 blackish brown. (Giinther.) Coast of Portugal and neighboring parts 

 of the Atlantic, occasionally taken in deep water off Gloucester, Mass., 

 and off the banks of Nova Scotia, (/co?3.o?, hollow ; Arfr, scale.) (Eu.)

Mouth little arched. Teeth of lower jaw with the point so much turned 

 aside that the inner margin of the tooth forms the cutting edge; upper 

 teeth erect, each with a long pointed cusp and 1 or 2 smaller ones on each 

 side; spiracles wide. Two species, in the Atlantic. (liymyov, to cut; 

 nrepov, fin, the original type having frayed fins.) 



74. ETMOPTERUS PUSILLUS, (Lowe). 



Body smooth, scales very small, each with a minnte tuberosity, but with- 

 out spines ; first dorsal fin much shorter than the second, midway between 

 second dorsal spine and the eye ; tail relatively shorter than in E. spinax, 

 its length less than the space between the snout and the origin of the pec- 

 torals; color brown. (Gunther.) 



The Blake took a single individual, believed to belong to this species, 

 at Station CVIII, off St. Christopher, in 208 fathoms. It had previously 

 been known only from Madeira and Cuba, and the Travailleur found it at 

 the Cape Verdes at about 290 fathoms. (Goode & Bean. ) (pusillns, weak.)
