THE FISHES OE PORTO RICO.

Genus 152. CORALLIOZETUS Evermann & Marsh. 
Body slender and strongly compressed, without scales; head large, subcylindrical, bluntly 
pointed; mouth large; teeth not hooked, about 8 enlarged conical ones in front of each jaw, smaller 
ones behind; vomer with teeth; dorsal fin with a notch between rays and spines; the membrane slightly 
connected with caudal; caudal fin rounded; pectoral large, ventrals small and inserted slightly in 
advance of pectorals. A strongly marked genus, conspicuous in appearance by its heavy head and 
thin body; probably related to Ophioblennius, from which it is technically separated by absence of 
hooked canine teeth, convex caudal, and entire absence of a lateral line. Only one species known.

271. Coralliozetus cardonae Evermann & Marsh. 
Head 4; depth 5.6; eyed; snout very short; maxillary 2; D. xvn, 11; A. 21; pectoral 1.3; ven- 
tral 1.8; caudal 1.4. Body scaleless, slender, much compressed; head large and heavy, not compressed 
nor depressed ; snout very short and blunt; mouth large, horizontal, low in position, maxillary reaching 
far beyond eye; eyes small, close together, placed high and well forward; teeth conical, in a patch on the 
front of each jaw, an outer row of about 8 teeth (4 on a side) in each jaw, much enlarged; a single row 
of smaller teeth on sides of each jaw; teeth on vomer; a small flap at nostril and two short filaments 
above eye, one much the smaller; no appendages at nape. Dorsal fin long and high, of slender, flexible 
spines, and longer, soft rays, a notch between fourth and fifth spines, last ray slightly connected with 
caudal; anal longer and lower than soft dorsal, free from caudal; caudal rounded; pectoral large, nearly 
as wide as body, reaching anal or beyond; ventral small, inserted before pectoral, of 3 rays, innermost 
very slender. 
Color in spirits: Body dark-red, much paler in one specimen; head everywhere bluish-black, 
this color dusted upon body, particularly on anterior portion; a pale-gray bar downward and back- 
ward across cheek; fins pale, except ventrals and front of dorsal, which have color of head; a row of 
small rosy spots along bases of anal rays, seemingly in the flesh; sometimes a similar fainter row 
along base of dorsal. 
Known only from Porto Rico; three specimens, 0.87 to 1 inch in length, taken on the coral reefs 
at Ponce on three successive days; type, No. 49377, U. S. N. M., 1 inch long, collected February 1, 1899.

Genus 153. EMBLEMARIA Jordan & Gilbert. 
Body slender, not eel-shaped, compressed, scaleless. Ventrals present, jugular, each of 1 spine 
and 2 soft rays. A single high dorsal fin beginning on nape and extending to caudal, with which it is 
not confluent; no notch between spinous and soft rays. Head cuboid, compressed, narrowed anteriorly. 
Symphysis of lower jaw forming a very acute angle. A single series of strong, blunt, conical teeth on 
each jaw, and on vomer and palatines. Vomer and palatine teeth larger, their series continuous, 
parallel to series in upper jaw. No cirri at nape; sometimes a cirrus on upper part of eyeball. Gill 
openings very wide, membranes broadly united below, free from isthmus. Lateral line obsolete.
