The form called Mursenn kauila by Jenkins is described as follows: 
Head 7.3; depth 16; tail a little longer than head and trunk; snout 4 in nead; eye 1.5 in snout: 
interorbital 2.25; mouth 2 in head. 
Body elongate, compressed; tail tapering posteriorly; head elongate, pointed, sides swollen a little 
above behind eyes; snout long, slightly convex in profile; mouth large; jaw arched, not completely 
closing, upper slightly the longer; teeth uniserial in jaws, compressed, with long canines with inter- 
vening smaller teeth; 2 large depressible canines on vomer; 3 or 4 large depressible canines below eye, 
forming an inner series on each side of upper jaw; lips thin, not concealing teeth when mouth is 
closed; eye about midway in length of mouth; nostrils in long tubes, the posterior larger, equal to 
eye; interorbital space flattened; gill-opening small, 0.75 in eye; roof of mouth with a single median 
series of small teeth beginning below front margin of eye and running back well beyond its poste- 
rior margin; dorsal beginning nearly midway between corner of mouth and gill-opening; caudal small, 
rounded. 
Color in life, light brown, with 2 longitudinal rows of dark brown spots about the diameter of 
snout gradually fading into one row on the posterior portion of the tail; many clear white spots as 
large, or larger than pupil, over head, body, fins, and tail, many of the spots forming more or less 
distinct vertical rows over fins and dorsal portions, some confluent on throat and belly, each one 
surrounded by a dark-brown margin; about 30 white spots crossing the ventral line; nasal tubes bright 
red; bright red bars on snout and lower jaw, and bright red undulations posterior to angle of mouth. 
Color in alcohol, brown, with the white and dark brown spots distinct; white spots edged with 
dark brown; bright red undulations posterior to angle of mouth fading out. 
A. single specimen, the type, No. 50684, U. S. Nat. Mus. (original No. 304), 13 inches long, taken 
by Dr. Jenkins from the coral rocks on the reef at Honolulu in 1889. The Albatross also obtained an 
example at station 3881, Napili Harbor, Maui, in 1902.

Genus 55. ENCHELYNASSA Kaup. 
Fore nostril funnel-shaped and capable of being shut up by a valvular elongation of its hinder 
border. Hinder nostril nearly as big as the eye, with a raised border. Rictus of the jaws open in 
the middle. Nasal bone reaching as far back as the middle of eye, armed with 27 teeth on its 
circumference, a pairless one in the middle and 5 longer ones, between the second and third of which 
stand 3 or 4 small ones, between the third and fourth 4 small ones, and between the fourth and fifth 1 
small one. Palatines 16, whereof the second, onward to the sixth, are supported before and behind 
by small teeth; on the inner row there are 9 longer acicular teeth. On the mesial line 3. On the 
vomerine no more than 2 small conical toothlets visible. Mandibulars, 22 smaller ones in the outer, 
and 6 to 8 longer in the inner row, approximated to the symphysis. The eyes are situated above the 
middle of t he jaws. There are 4 pores on the upper jaw and mandible difficult to find in the porous 
skin. (Kaup.) 
This genus is distinguished from Gymnothorax by the enlarged and dilated posterior nostril, which 
suggests the. nostril of a horse. The teeth are very numerous, some of them being long and sharp, as 
in the Japanese genus JEmaria. These are morays of huge size, found in the Pacific, perhaps all 
belonging to one species; but if so, the variation in the number of teeth is considerable.

Head, measured to gill-opening, 7.1 in the length; depth 9; snout 5.5 in head; eye3insnout; inter-
