NEW GENERA AND SPECIES OF FISHES FROM PUERTO RICO. 357 



GILLIAS Evermann & Marsh, new genus. 



Gillias Evermtinu A: Marsh, new genus of Blenniidw {jordani). 



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 ten- 

 tacle above eye ; dorsal fin divided iuto 3 parts, the first of 3 short spines, the second 

 of 11 longer spines, and the third of 7 rays. 



This genus is closely related to Enneanectes Jordan & Evermann, from which it 

 differs in the presence of the orbital tentacle, the more complete develojiment of the 

 lateral line, and the larger scales. 



Named for Dr. Theodore Gill. 



11. Gillias jordani Evermann & Marsh, new species. 



Head 3.5; depth 4.3; eye 2.5; snout 3.5; maxillary 2.4; mandible 1.9; scales 

 2-30-7; D. iii-xii-7; A. ii, 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 largo, high up, interorbital width very narrow; a broad 

 bifid orbital tentacle, 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 ; doi'sals 3, the first of 3 hhort, flexible spines, close to 

 the second, which has 12 longer, rather stiflfer, spines, separated from the 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 2, slender. 



Color in alcohol: Brown, body crossed by 4 broad blackish bars, one at the 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. 



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 

 Eeef, at Ponce, February 1, 1899, and another specimen of about the same size taken 

 at the same place the preceding day. 



Named fur Dr. David Starr Jordan. 



12. Malacoctenus culebrae Evermann & Marsh, new species. 



Head 3.35; depth 5; eye 4.2; snout 4.5; maxillary 2.2; mandible 1.8; interorbital 

 6.5; scales 2-35-11; D. xxi, 8; A. ii, 18; pectoral 1.3; ventral 1.3; caudal 1.4. 



Body slender, compressed; head rather long, pointed, upper profile convex; mouth 

 large, the maxillary nearly reaching posterior border of orbit ; lips thick, j aws equal ; 

 teeth very small, conical, a single row in each jaw; a single nasal, ocular, and 

 nuchal filament; dorsal fin moderately high, originating above the origin of lateral 

 line, a shallow notch in front of last two dorsal spines, the membrane free from 

 laudal; anal origin under about tenth dorsal spine; caudal somewhat pointed; 

 pectoral large, reaching anal ; ventrals moderate, not reaching anus, of two rays, no 

 spine evident; lateral line distinct throughout, running high anteriorly, where it is 

 slightly curved, turning abruptly downward over the origin of anal, thence median 

 to base of caudal. 



Color in spirits: Body everywhere mottled with dark brown, in somewhat regu- 

 larly arranged blotches, a series of about nine of these at the base of dorsal, barely 

 extending upon the fin; a similar series of much smaller ones at base of anal, not
