APODAL FISHES OF AMERICA AND EUROPE. 
623 
Etymology: Latin, quassm , obliterated; remux , oar, from the minute 
pectorals. 
This new generic name is proposed for two species, nothochir and 
evionthas , which agree with Ophichthus in all respects except that the 
pectoral fins are rudimentary.

a. [ Body marked with rather large yellow spots, each with a black ring, and with 
black spots and blotches of various sizes ; pectorals minute, less than £ of eye. 
Teeth all uniserial ; pectorals represented by a small triangular flap, less than £ 
the diameter of eye and £ the gill-slit ; head 4-J- in trunk ; head and trunk longer 
than tail by a distance equal to the length of the snout ; cleft of mouth 2 i in 
head; snout 4 in head; eye ^ of snout, its anterior margin over middle of cleft
