Dorsal spine li/4 ^^^ head, front and hind edges terminally ser- 

 rated; first dorsal ray 1% (fin apparently separate from second 

 dorsal); second dorsal uniformly low, length 2% in total length; 

 supracaudal little shorter than subcaudal which begins slightly be- 

 fore supracaudal but without notch to indicate anal; pectoral 

 reaches middle of ventral, 41/3 in total length, width 2 in its length ; 

 ventral 1% in head, pointed. 



Silvery above and on sides, yellowish below. Snout tip black. 

 Eye yellow. Lateral line raised, brown. Markings formed as narrow 

 bands passing obliquely from behind forward and downward, con- 

 fined to head and front part of body and formed of brown splashes 

 which below become rings, also extend across chin and pectoral bases. 

 Above lateral line whole body marked with 25 narrow transverse 

 broken lines, oblique on tail. Fjn membranes bluish black, bases 

 of paired fins horn color. Caudal filament yellow. Length, 860 mm. 

 (caudal filament incomplete). (Waite.)

Chimaera tsengi Fang and Wang, Contr. Biol. Lab. Sci. Soc. China, vol. 8, 

 p. 281, fig. 29, 1932 (type locality: Chef 00; Chinhai; Chekiang). 



Depth 11/5 in head length ; head greater than 5 in length to supra- 

 caudal origin, width 2 in its length. Snout 2i/^ in head, soft and 

 triangular jn anterior profile, without rostral appendage; eye 4i/^, 

 1% in snout, greater than interorbital ; mouth small, inferior; teeth 

 2 in each jaw, upper with 10 laminae forming serrated cutting edge, 

 anterior one pointed, posterior very short, broad and its hind edge 

 more or less roughened; laminae of lower jaw 8 each side, forming 

 broadly concave cutting edge; vomerine tritors 1 anterior and 2 

 posterior on each side which much elongated, 1 tritor in inner wall 

 of lower teeth; nostrils large, close together, short space before 

 mouth. Gill opening small, before pectoral base. 



Lateral line wavy anteriorly, less so below front part of second 

 dorsal and straight posteriorly ; an upward curve below supracaudal 

 origin and posteriorly along subcaudal base. 



First dorsal spine I14 in head, compressed, pointed, straight, front 

 edge smooth and keeled, hind edge serrated, especially its tip and 

 with shallow groove, when depressed nearly reaches second dorsal 

 origin; second dorsal very long, uniform, joined to first dorsal by 

 very low rayless fold of skin and separated from supracaudal by 

 deep notch. Anal confluent with subcaudal. Caudal with very short 

 filament; supracaudal much lower than second dorsal and shorter 

 than subcaudal. Pectoral I14 times head, width I14 times its length, 

 with thick muscular base, when depressed reaches far posterior to 

 ventral base.
