(TlMUCU.) 



Head about 3. D. 13 or 14; A. 15 or 16. Very close to Tylosurus mari- 

 wi/, but with smaller eye, 3 to 3i in postorbital part of head, and fewer fin 

 rays. Surinam to Rio de Janeiro, and probably northward in the West 

 Indies. Known to us from the specimens called Belone tinmcu by Cuvier

1061. TYLOSURUS FODIATOR, Jordan & Gilbert. 

 (AGUJOW.) 



Head about 3f ; depth 15 ; eye large, 6i in snout, 3 in postorbital part 

 of head, and 2 in interorbital width. D. I, 19; A. I, 17; V. 6; P. 14; 

 scales 440. Bqdy robust, the caudal peduncle with a strong keel, black 

 in color; one or more folds of skin across edge of preopercle; caudal 

 unequally forked; dorsal with its last rays elevated in the young. Beak 

 short and very strong, the snout 1| times length of rest of head. Dorsal 

 inserted opposite anal ; ventrals inserted midway between base of caudal 

 and middle of eye. Cheeks closely scaled, opercles nearly naked ; scales 

 extremely small. Color green above, silvery below ; fins somewhat dusky, 

 except the anal, which is pale ; cheeks and lower jaw silvery ; middle 

 line of back darker ; scales and bones a very bright green ; no distinct 

 lateral stripe. Length 3 to 5 feet. Pacific coast of Mexico ; common about

 rapliidoma by its fewer fin rays, (fodiator, one who stabs, this species, 

 like the next, being often dangerous to fishermen.)

 dal peduncle slightly depressed, a little broader than deep, with a slight

 groove, which is wider behind and forks at the nape. Supraorbital bones

 ing forward; large teeth of jaws very strong, knife-shaped. Upper jaw
