its upper edge. Pectorals large, not reaching the bases of the ventrals. Outer 
angles of ventrals sharp. Dorsal spine more than half as long as the head, 
hardly keeled in front. Subcaudal about as wide as the supracaudal. No sepa- 
rate anal fin. Eye small, less than one sixth as long as the head. Caudal 
filament short. Lateral line with few and weak undulations; jugular branch 
meeting the postorbital near the junction of the latter with the suborbital and 
the angular sections. Clasper of male trifid in the distal third of its length. 
Uniform plumbeous. 
North Atlantic, from Portugal westward, in depths of from 300 to more 
than 900 fathoms. 
CHIMAERA WAITEI. 
Hydrolagus (Psychichthys) waitei Fowuer, 1908, Proc. Acad. Nat. Sei. Phil., p. 419, f. 1. 
Head three elevenths of the length from end of snout to end of second dorsal, 
little more than half of the second dorsal base. Dorsal spine as long as the 
head in a twelve inch specimen, keeled in front, reaching the origin of the second 
dorsal. No distinct anal. Subcaudal rather narrower than supracaudal. 
Caudal filament short. Eye small. Lateral line not wavy in the middle of 
the side; jugular section meeting the postorbital near the junction of the latter 
with the angular and the suborbital sections. Second dorsal not indented in 
the upper edge. 
Type about twelve inches in length.

CHIMAEBRA MEDIA, sp. nov. 
Hye large, length of orbit nearly one third of that of the head. Head about
