Chimaera ogilbyi Waitt, 1898, Thetis Prelim. Report, p. 56; 1899, Mem. Austral. Mus., 4, p. 48, pl. 6. 
Head one fourth of the length from snout to supracaudal, about three 
sevenths of the length of the second dorsal. Eye small, length near one fifth 
of the head. Upper margin of second dorsal not indented. Outer angles of 
pectorals and ventrals sharp. No anal fin. Caudals low, supracaudal little 
higher than subecaudal. Pectorals reaching beyond the origins of the ventrals. 
Dorsal spine hardly reaching the base of the second dorsal. Lateral line with 
short waves on the greater part of the flank; jugular section meeting the orbital 
near the junction of the latter with angular and suborbital sections. Caudal 
filament elongated. 
Silvery on back and sides, yellowish below. Toward the back of the head 
on the body there are narrow darker bands passing down and _ obliquely 
forward. Anteriorly there are small spots which become rings farther down. 
Posteriorly the twenty or more transverse streaks above the lateral line are 
more or less broken.

spine little more than half the length of the head, not serrated, reaching the 
base of the second dorsal. Greatest depth of second dorsal equal to the length 
of the orbit, upper border not concave. No separate anal. Pectoral large, 
reaching beyond the origins of the ventrals, not faleiform, rather broad. Sub- 
caudal larger than supracaudal. A caudal filament. Lateral line feebly un- 
dulated; jugular section meeting the angular at the junction with orbital and 
suborbital sections. Type 90 em. in length. 
Uniform purplish or plum color.
