472 Goode and Bean—Two new species of Fishes. 
scale. Number of scales in laieral line, 152; six transverse 
rows above it, and nineteen or twenty rows below it, counting 
from vent obliquely backward. : ; 
Head.—Greatest length (0°045 m.) equals distance between 
first and twenty-third anal rays, and is contained six and one- 
half times in extreme length. Greatest height, at posterior 
margin of orbit, (0°028 m.) greater than width at same point 
(0023 m.), and contained one and four-seventh times in length 
of head. Width of interorbital area (0-012 m.) equal to verti- 
cal diameter of orbit (0°012 m.), and almost equal to length of 
snout (0018 m.) and length of maxillary (0013 m.). Length 
of post-orbital region (0°017 m.) about equal to horizontal 
diameter of orbit (0-016 m.). Length of operculum (0-007 m.) 
about half the length of mandible (0:015 m.). 
nout sharp, a front view presenting four ridges radiating 
from the tip at right angles to each other, the lower one being 
merely a fold in the skin of the under surface of the head. 
he horizontal ridges are continued into the ridges upon the 
suborbitals. Ridge extending backward from tip of snout upon 
top of head is lost in the interorbital space. Branches of the 
horizontal ridges are continued upon the upper margins of 
orbits, and there disappear. Nostrils immediately in front of 
orbit, the posterior pair much the longer. 
outh situated entirely on lower side of head; symphysis of 
lower jaw in vertical from anterior margin of orbit, and articu- 
lations of mandibles in vertical from posterior margin of orbit ; 
width of cleft of mouth (0°012 m.) equal to distance between 
symphysis of maxillaries and line connecting their articulations. 
ha) 08 jaw protractile vertically. Barbel 0-005 m. in length. 
eeth conical, somewhat recurved, of nearly uniform size, 
arranged in villiform bands. Palate smooth. 
Distance of first dorsal from snout (0:057 m.) about four
