Fishes of the Western North Atlantic 243 



Dorsal fin with the longest rays not quite reaching tip of last ray if deflexed, its 

 origin equidistant between base of caudal and middle of eye. Anal origin slightly in 

 advance of middle of dorsal base, its base 3.9 in SL. Pelvic reaching less than halfway 

 to anal, inserted nearer to base of pectoral than to origin of anal. Pectoral not quite 

 reaching base of pelvic, 1.3 in head. Axillary scale of pectoral fully 75''/o of fin, 

 1.8 in head. 



Color. Grayish above. Sides silvery. No lateral band. Caudal with a narrow dark 

 margin. 



Range. Known only from the type taken at Port-of-Spain, Trinidad.

Study Material. Type material, 3 specimens 237, 230, and 205 mm long, from 

 the Rio Poty, Brazil, and a fourth specimen, 220 mm long, from the fish market at 

 Para; holotype and one paratype, MCZ 35277 and 18017, respectively; second paratype 

 USNM II 8997; and fourth specimen SU 22086. 



Distinctive Characters. This species differs from L. batesii in having a deeper body, 

 a somewhat more posteriorly placed anal fin, and much shorter and broader gill rakers; 

 however, the rakers are about equal in number in the two species, h. schroederi Hil- 

 debrand, known only from Rio Doce in southern Brazil, is another related species; it 

 has more numerous but equally short, broad, spiny, partly rudimentary gill rakers 

 (17 or 18 -I- 2 1 or 22 on the first arch), a larger eye, about 4.9 in head, and a more 

 posteriorly placed anal, its origin under the posterior third of dorsal base. 



Description. Proportional dimensions in per cent of standard length, and counts, 

 based on the four study specimens, 205—237 mm. 



Body: depth 21.2—23.2. Anal fin: length of base 24.3—26.2. 



Head: length 22—25.5. Pectoral fin: length 17— 18.2. 



Snout: length 2.75-3.0. 



Eye: diameter 4.25-4.45. Scales: ca. 40-45. 



Postorbital: distance 14. 5-1 7.7. Gill rakers: 9-1 1 + 12-14. 



Maxillary: length 18.2— 21. Fin rays: dorsal 14 or 15; anal 26-28; 



Mandible: length 17.5—20.8. pectoral 14 or 15. 



Body rather strongly compressed, its depth 4.3-4.7 in SL. Head 3.9-4.5 in SL, 

 its depth about equal to its postorbital length. Snout projecting much less than half
