21. Lycodontis albimentis Evermann & Marsh, new species. 
Head 6.4; snout about 7; mandible 1.8; eye 2.3 in cleft of mouth; head and trunk somewhat 
compressed, tail considerably so; cleft of mouth a little less than half of head; jaws equal; teeth strong, 
conical, and sharp, in one rather irregular row in upper jaw, strongest in front; in lower jaw one row 
of similar teeth, becoming smaller posteriorly, those in front stronger than in upper jaw; eye rather 
large, slightly nearer tip of snout than angle of mouth, bordering the lip; upper lip with a row of very 
minute cirri along the edge, resembling teeth, visible only under a lens; a row of rather large pores 
around upper lip and a pair on top of snout; anterior nostril tubular, in the lip at angle of snout; pos- 
terior nostril without tube, just above front of eye; fins h.gher posteriorly. 
Color in spirits: Everywhere uniform dark-brown, except lower part of head and edge of fins; 
upper lip and lower jaw perfectly white, the brown sharply demarcated from the colorless area, which 
begins just back of mandible, extending over lower jaw, past angle of mouth, along upper lip, under eye, 
and around snout; inside of mouth colorless; fins darker than body, narrowly pale-edged posteriorly. 
One very small specimen, only 2 inches long, brought up by the tangle from coral bottom in 15 
fathoms at Fish Hawk station 6093, off Culebra Island, February 8; possibly the young of a known 
species, but the sharply defined white area on the lower jaw is so prominent a character that we have 
thought it best to describe the species as new. Type No. 49527 U.S.N.M. 
Pig. 9. — Lycodontis albimentis. 
22. Lycodontis jordani Evermann & Marsh. 
(Plate 2.) 
Head 7 in total length; depth about 14; eye 8 in head; snout 5; gape 2.2; interorbital a little 
less than snout. Teeth uniserial, strong, sharp, not close-set, all entire and without basal lobes; tail 
considerably longer than rest of body; gill-opening smaller than eye; snout rather pointed, lower jaw 
the shorter, the mouth capable of being completely closed. Dorsal fin high, much higher than anal; 
nasal tube long, about 3 in eye. 
Color in life: Tawny-ochraceous, paler below; upper jaw gray; iris blue; longitudinal brown stripes 
on side of head in front of gill-opening; head and body covered with numerous small, round, white spots, 
those on head smallest; a series of larger ones along upper part of side, and one or two irregular series 
of large ones on side of belly; between these, on middle of side, the sjiots are smaller; dorsal with an 
irregular series of small white spots along the base, and another series of about 16 much larger, more 
quadrate spots of same color along edge of fin, some of the spots cutting the border, which is black; 
anal similarly spotted and with black border.
