Maxillary: length 9.0-12. 

 Mandible: length 1 2-14.5. 

 Anal fin: length of base 10-14. 

 Pelvic fin: length 11 -15. 

 Pectoral fin: length 14-17. 

 Distance from snout to origin of: dorsal 

 44-50. 



Scales: 33—37, generally missing in pre- 

 served specimens. 



Gill rakers: 19—24 (usually 20 or 21) on 

 lower limb. 



Fin rays: dorsal 9—13; anal 12—15; P^'^" 

 toral 10-13. 



Vertebrae: 39 or 40 (6 specimens). 



Figure 64. Jenkinsla lamprotaenia, 65 mm TL, 53 mm SL, Haiti, USNM 89600. Drawn by Ann S. Green. 



Body moderately compressed, its greatest thickness somewhat greater than half of 

 its depth, its greatest depth 5.0—6.65 in SL; ventral outline more strongly convex 

 than dorsal outline. Caudal peduncle rather strongly compressed, its depth 3.2—4.1 

 in head. 



Scales generally lost in preserved specimens, very thin, with smooth edges; those 

 from middle of side below dorsal fin with a wavy ridge on anterior half, about 5 wavy 

 radii behind it, and generally several shorter ridges at margin of scale. 



Head rather low, 3.4—4.0 In SL. Snout generally shorter than eye, 3.4—4.2 in 

 head. Eye 2.8—3.4. Interorbital 5.5—7.0. Maxillary narrowly rounded posteriorly, 

 reaching to or more usually a little beyond vertical from anterior margin of pupil, 

 2.25—2.75 in head. Mandible generally included, not projecting, 1.9-2.2 In head. 

 Gill rakers moderately close-set, those at angle of first arch about 75 "/o of length 

 of eye. Teeth missing on mandible and vomer but present In a single series on 

 margin of premaxillary and maxillary, the series interrupted by a soft membranous 

 section between these elements; palatines, pterygoids, and tongue at most with a few 

 granular teeth. 



Dorsal fin moderately elevated, the margin nearly straight, the longest rays reach- 

 ing well beyond the tip of last ray if deflexed, the fin beginning notably nearer to margin 

 of snout than to base of caudal, the distance from margin of snout 2.0—2.3 in SL. Caudal 

 fin moderately forked, the lobes of about equal length, rather longer than head without 

 snout; each lobe with a greatly elongated scale at base. Anal fin much lower than dorsal, 

 beginning far behind dorsal fin, about equidistant between insertion of pelvic and base
