Body rather strongly compressed, its greatest thickness about equal to depth of 

 caudal peduncle, its depth 3.9-4.5 in SL. Head short, 3.7-4.1 in SL, its depth equal 

 to its postorbital length and about 66 "/q of diameter of eye. Snout extending about 

 66 "/o of its length beyond mandible, 5.7-6.6 in head. Eye 3.4-3.7. Postorbital 

 1.9— 2.1 in head. Maxillary pointed, extending nearly to margin of opercle, 1.2— 1.4 

 in head. Mandible i. 4-1. 53. Cheek about as long as eye and half of snout, its 

 posterior angle about 40°. 



Dorsal fin moderately high anteriorly, its longest rays reaching beyond tip of 

 last ray if deflexed, its origin equidistant between base of caudal and a point at anterior 

 half of eye. Anal origin under, or somewhat in advance of, middle of dorsal base, its 

 base 3.0—3.4 in SL. Pelvic reaching fully halfway to anal, inserted a little nearer to 

 origin of anal than to base of pectoral. Pectoral sometimes not quite reaching to pelvic, 

 1.35— 1.52 in head. Axillary scale of pectoral rather broad at base, scarcely extending 

 to vertical at midlength of fin, 2.8-3.6 in head. 



Figure 29. Anchoa trinitatis, type specimen, from Port-of-Spain, Trinidad, ANSP 45083, modified after 

 Fowler (191 5: 527, fig- 3). Drawn by Alice C. Mullen. 



Color. In alcohol, pale above. Side of head and lower part of body silvery. Silvery 

 lateral band faint, narrower than pupil, missing in specimens presumably preserved 

 originally in formalin. Back and upper surface of head with dusky punctulations, some- 

 times forming two almost continuous lines posterior to dorsal fin. 



Si-ze. The largest individual seen is 1 10 mm TL. 



Range. So far as known, this species is confined to four localities: Port-of-Spain 

 and Vessigney, Trinidad; Laguna de Tacarigua (on coast 85 miles east of Caracas), 

 and Rio Caiio de Sagua, Sinamaica, Venezuela.
