159. Eucinostomus harengulus Goode & Bean. Mojarra. 
Head 3; depth 2.7; eye 3.2; snout 3; maxillary 2.8; mandible 1.8; interorbital 4; scales 5-45-10; 
D. ix, 10; A. in, 8. Body compressed, slender, back not much elevated; snout rather long and 
pointed; mouth horizontal, moderate, maxillary reaching anterior edge of pupil, its exposed portion 
triangular; preorbital and preopercle entire; premaxillary groove narrow, naked; eye rather large. 
Fins moderate; second dorsal spine slender, weak, 1.8 in head, shorter than the third; second anal 
spine short and weak, 3.2 in head, a little shorter than the third; caudal moderately forked, pectoral 
long and pointed, not quite reaching anal, 1.1 in head; ventrals short, not reaching vent, 1.9 in head. 
Color in life: Silvery-white, the back with pale steel-blue iridescence; faint, shining, silvery- 
longitudinal stripes along rows of scales; fins all pale except tips of dorsal spines, which are black. 
E. harengulus is very close to E. californiensis and may not be really distinct. The principal differ- 
ence we discover between our specimens and specimens of E. californiensis from the Pacific coast is 
that the second anal spine is somewhat larger in E. harengulus. Length 4 to 8 inches. It is found 
on the Atlantic coast of tropical America from Florida to Bahia; apparently the most abundant species 
of the family in Porto Rico, as is shown by numerous specimens from San Antonio Bridge and Palo 
Seco near San Juan, Mayaguez, Boqueron, Fajardo, Isabel Segunda, San Geronimo, and Culebra.

Head 3.2; depth 2.5; eye 3; snout 3.2; maxillary 3; mandible 2; interorbital 3; scales 4-45-9; 
I), ix, 10; A. nr, 8. Body compressed, rather short, back somewhat elevated; profile straight from 
tip of snout to occiput, thence arched to origin of dorsal; mouth rather small, horizontal, maxillary

Genus 90. ULJEMA Jordan & Evermann. 
This genus is close to Eucinostomus, from which it differs in the form of the second interhsemal, 
which is short, bluntish, and not hollowed out. The single known species is slender in form, with 
weak spines, the anal fin having but 2.
