THE FISHES OF PORTO RICO. 
307 
qq. Jaws each with 8 enlarged curved, conical teeth, not hooked, behind which is a single row of smaller ones; caudal 
fin not forked Coralliozetus, 152 
pp. Jaws with numerous teeth, not as above; caudal fin not forked. 
liMBLEMA RIIN/E: 
r. Body not eel-shaped; dorsal and anal not joined to caudal: no scales; no cirri; no lateral line; ventrals before pec- 
torals; teeth on palatines; caudal fin rounded. Dorsal fin very high, not notched, spines passing gradually 
into soft rays; jaws long, sharp at tip Emblemaria, 153 
Genus 147. GILLIAS Evermann & Marsh. 
Body short and stout, tapering rapidly from the short, broad head to the short, compressed caudal 
peduncle; scales large, rough-ctenoid; lateral line complete, or nearly so, broken under last spines of 
middle dorsal; a broad, double-pointed tentacle above eye; dorsal fin divided into 3 parts, first of 3 
short spines, second of 1 1 longer spines, and third of 7 rays. 
This genus is closely related to Enneanectes Jordan & Evermann, differing in the presence of the 
orbital tentacle, the more complete development of the lateral line, and the larger scales.

259. Gillias jordani Evermann & Marsh. 
Head 3.5; depth 4.3; eye 2.5; snout 3.5; maxillary 2.4; mandible 1.9; scales 2-33-3, 6 in 
transverse series; D. m-xn-7; A. n, 15; longest dorsal spine 1.8 in head, longest ray 1.6; longest anal 
ray 2.3; pectoral 0.8; ventral 1.3; caudal 1.3. Body short and stout, tapering rapidly to the short, 
compressed caudal peduncle; head short; snout short, blunt, concave in front of eyes; mouth small, 
slightly oblique, jaws equal; eye large, high up, interorbital width very narrow; a broad bifid orbital 
tentacle and a short nasal one; none on nape. Scales very large and rough-ctenoid; opercles and entire 
head rough; lateral line nearly complete, beginning immediately above base of pectoral at upper end 
of gill-opening and extending parallel with back to posterior part of middle dorsal fin (or for 12 scales), 
where there is a break, the line dropping down 3 scales, then continuing with one or two interruptions 
to base of caudal; belly and breast scaled; dorsals 3, first of 3 short, flexible spines, close to the second, 
which has 12 longer, rather stiffer, spines, separated from third by a space one-third diameter of eye; 
anal long and low, the membranes deeply notched between the rays; pectoral of 15 rays, broad and 
short, reaching posterior end of second dorsal; ventral of 2 slender rays. 
Color in alcohol: Brown, body crossed by 4 broad blackish bars, one at origin of second dorsal, 
one under last spines of same fin, the third between second and third dorsals, and the fourth under 
third dorsal; an inky-black bar across caudal peduncle at base of caudal fin; head and under parts rusty; 
fins all barred with light and dark; caudal with a narrow light bar at base, then a black one, then a 
broader white one, followed by a much broader dark bar containing some white areas, the fin finally 
tipped with white. 
Known only from Porto Rico. Two specimens of this well-marked and interesting species were 
obtained, the type, 1.5 inches long (No. 49368, U.S.N.M.), taken on the Cardona Light-house Reef, at 
Ponce, February 1, 1899, and another of about the same size taken at the same place the preceding day .
