46. Cichlasoma teapae, new species. 
Type, No. 50005, U.S.N.M., a mature male 9.5 inches long, collected April 1, 1900, by E. W. Nelson 
and E. A. Goldman, in the Bio Teapa, at Teapa, Tabasco, Mexico. Cotype, No. 976, U.S.F.O. reserve, 
a well preserved specimen, 8 inches long, collected at the same time and place. 
Head 3.75; depth 2.6; eye 5; snout 2; maxillary 4.5; mandible 3.5; interorbital 2.6; preor- 
bital 3.2; D. xvn, 13; longest dorsal spine 2.3 in head, ray 1.2; A. vi, 9, longest anal spine 2.2, ray 
1.25; pectoral 1.5; ventrals 1.2; caudal 1.5; scales 6-33-12, 5 rows on cheek. Body comparatively 
slender, compressed; caudal peduncle much compressed, its least width 3 in its least depth; head 
short, compressed, its anterior profile ascending very abruptly from the short, blunt snout; a high 
nuchal crest or hump, highest above eyes, the anterior profile thus made concave in front of eyes; 
snout short, anterior profile ascending abruptly; mouth small, nearly horizontal; jaws subequal, or 
the lower slightly included; teeth strong, canine-like, tips brown; eye rather small, entirely above tip 
of snout; dorsal fin beginning over base of pectoral, the spines rather slender and weak; soft rays of 
dorsal long, reaching base of caudal; anal spines stronger than those of dorsal, the rays somewhat 
longer; caudal fin truncate; pectoral rather broad, not reaching tips of ventrals; ventrals long and

pointed, extending slightly beyond vent in type, not quite reaching it in cotype; tips of dorsal and 
anal extending slightly beyond base of caudal. 
Color in alcohol, dusky white, paler on belly, the outer half of exposed portion of each scale 
brownish black, the distinction between this and the pale base of the scale being very marked; traces 
of four or five dark vertical blotches on side under dorsal fin and one at base of tail; trace of black 
blotch under and above tip of pectoral; entire head pale brownish; dorsal, anal, and caudal brownish, 
apparently without spots; pectoral and ventrals pale. 
This species is related to C. melcmurus, but differs from it in the more slender body and very 
different coloration. It also resembles IJeros gibbiceps Steindachner, the type of which also came 
from Teapa, in the strong development of the nuchal crest. From that species it differs in the presence 
.of a frenum on lower jaw, which makes it a true Cichlasoma, and in the different coloration.
