Type: No. 9669, Ind. Univ. Mus., a specimen 160 mm. long, from San Juan. 
This is a narrow, deep fish with projecting lower jaw, a pointed snout, and a depression in the. 
profile over eyes. D. xv, 11; A. iv, 9; depth 2; head 2.7; depth of caudal peduncle 2 in head; scales 28; 
pores, 18 + 12; snout pointed 2.75 in head; eye 4.5 in head, 1.5 in interorbital; no foramen in 
upper angle of gill-opening; maxillary reaching vertical from front of orbit; highest dorsal and anal 
rays reaching to end of basal two-fifths of caudal; highest dorsal ray twice as high as last ray, equaling 
longest caudal ray, equaling length of head without opercle; highest anal ray slightly shorter; ventrals 
to vent. 
Ashy gray, darker above to light below; each scale of lower parts of side with black spot on tip, 
extending over to next scale and forming distinct series; lower part of opercle, preopercle, lower part 
of cheek, and lower jaw with dark spots; vertical fins dusky; soft dorsal and anal spotted; ventrals

Heros tetracanthus cinctus Eigenmann, new subspecies. * 
'type: No. 9671, Ind. Univ. Mus., a specimen 129 mm. long, from Paso Real. 
Four specimens were taken at Paso Real measuring a 68, h 72, c 129, and d 136 mm. long, respec- 
tively, and differing in coloration from those taken at any other point. The two larger are very dark, 
one having very distinct markings.

The specimens approach 7/. nigric.nns but have a normal lateral line: c (the type) is most aberrant 
in its coloration, d approaches the coloration. of tetracanthus torralbasi from the Almendares, a and 5 are 
indistinguishable from other young except in the band through the lateral spot.
