1438. ULOCENTRA GILBERTI, Evermann & Thoburn, new species. 



Head 4| ; depth 6 ; eye 3 in head, longer than snout. D. IX-12 ; A. II, 

 9; scales 5-54 to 57-x. Body slender, fusiform, little compressed ; the 

 upper profile descending in a gentle, regular curve from front of dorsal 

 to tip of snout, which is below the axis of the body. Mouth small, hori- 

 zontal, the lower jaw included ; maxillary reaching vertical from front 

 of orbit, its length equal to diameter of eye ; premaxillaries protractile. 

 Interorbital space & diameter of eye. Gill membrane narrowly joined, 

 free from isthmus. Lateral line continuous, nearly straight, continued 

 forward to eye. Opercle and upper part of cheeks with scales similar to 

 those on body ; breast naked ; scales on median line of belly similar to 

 the others. Fins moderate, the pectoral reaching to tip of ventral and f 

 distance to anal, equal to length of head ; anal rather small. Color in 

 alcohol : Yellowish with dark tessellations above ; 8 to 10 oblong blotches 

 along the sides, with smaller blotches between and partly confluent with 

 them ; the coloration much as in Cottog aster copelandi ; upper fins barred. 

 Three specimens from Clinch River, at Walker's Ford, near Tazewell, 

 Tennessee, the longest 2 inches in length. (Type, No. 47531. Coll. Ever- 

 mann, Scovell, and Gurley.) (Named for Dr. Charles Henry Gilbert.) 



1439. ULOCENTRA YERECUNDA (Jordan & Evermann). 



Head 4-J ; depth 4| ; eye large, longer than snout, 3i in head. D. XI, 

 11 ; A. II, 7 ; scales 6-47-9. Form of head and body much as in PocciUch- 

 thys zonalis, the body subfusiform, little compressed, the back somewhat 

 elevated. Head small; snout short, very convex in profile. Mouth 

 small, inferior, horizontal ; premaxillaries protractile, but with traces of 

 an obsolete mesial frenum ; maxillary extending to just beyond front of 

 eye, 3f in head. Gill membranes broadly united; preopercle entire; 

 cheeks, opercles, and nape scaly ; breast naked ; lateral line complete. 

 Fins all very low ; dorsal fins scarcely joined ; caudal slightly lunate ; 

 pectorals as long as head, reaching tips of ventrals, not to vent. Color 



* Ulocentra ilarixmii (Hay). 



Head 4; depth 6%; eye 3; snout 1% in eye. D. IX-10, well separated; A. II, 6; scales f>-f,(l-7, 

 pores developed on about 30. Interorbital space narrow. Mouth large, horizontal, terminal, 

 the maxillary extending to a perpendicular from pupil; cleft of mouth % head; jaws about 

 equal; premaxillaries freely protractile. Cheeks and opercles densely scaled; breast naked; 

 opercular spine well developed; gill membranes narrowly connected; vomerine teeth apparently 

 present. Base of spiuous dorsal 4% in length of body, its height 7; base of soft dorsal shorter, 

 7 in length of body, its height about the same. Anal spines well developed, the first the stronger. 

 The pectorals reach to vertical of eighth dorsal spine, the ventrals falling short of tips of pec- 

 torals. Caudal peduncle compressed, tapering gradually to caudal fin. General color oliva- 

 ceous; many scales, each with a dark blotch, these uniting to form zigzag and ^-shaped 

 markings, especially above the lateral line; sides with about 10 larger and nearly square spots, 

 the largest on caudal peduncle; belly and chest under a lens are seen to bo thickly sprinkled 

 with black dots; a black streak downward from eye and another forward to snout; fins dusky; 

 both dorsals with rows of dusky spots between the rays; caudal barred. One specimen known, 

 Yellow River, near Chaffln, Santa Rosa County, Florida. This is probably identical with 

 Ulocentra stigmsea.
