Rhinochimaera (Harriotta) pacifica Dean, 1904, Journ. Coll. Sci. Tokyo, pl. 1-2. 
Snout narrow, high, produced, pointed. Body, head, and snout compressed; 
back hardly elevated above the level of the snout and the tail. Forehead con- 
tinuous into the snout, not decurved. First dorsal subtriangular; spine not 
reaching the origin of the second dorsal. Second dorsal low, hardly as wide as 
the orbit, little longer than the snout, as long as the space between the origins 
of the pectorals and those of the ventrals. Ventrals small, nearly as large as 
the first dorsal. Pectorals large, broad, not reaching the origins of the ventrals. 
Supracaudal very low, armed on the upper edge with spines, in a double row. 
Subcaudal much larger, longer, and wider; width about that of the orbit. 
Caudal filament about as long as the snout. No anal fin. Lateral line nearly 
straight from the ocular and the orbital sections backward to a point below the - 
origin of the supracaudal; jugular section meeting the orbital a short distance 
behind the junction of the latter with the suborbital and the angular; prenasal 
section not passing up on the side of the snout but continued forward between 
the nasal and the suborbital to the subrostral. See figures in Garman, 1904, 
Bull. M. C. Z., 41, pl. 2, f. 1 and 2. Teeth with sharp cutting edges, without 
notches or undulations, Garm., loc. cit., pl. 5, f. 1 and 2. An adult male is-about 
three feet in length, a female about four. 
Sides and below light silvery olive or plumbeous brown; back, tail and fins 
distally darker.

HARRIOTTA. 
Harriotta Goopvr and Bran, 1904, Proc. U. S. Nat. Mus., 17, p. 471. 
The snout in this genus is elongate, depressed, and somewhat flattened; 
the forehead curves down in front to the snout; the teeth have tritors and 
sinuous or notched cutting edges; the supracaudal is of moderate height and not 
armed by spines on its upper edge, and the frontal tenaculum of the male has 
an elongate much curved stem to comport with the downward curvature of 
the forehead,
