Mouth sli^;htlv more oliliiiiu- than in I.ariiinis arc/ivis, much less so than in /,. arfft>i/ri/.<:. 

 PremaxillarifS anteriorly on a level with middle of pupil (lower part of pupil in L. acclivis). Maxillary 

 about reachinjf vertical from front of pupil, 2^ to 2\ in head. Teeth minute, close-set, even, in a single 

 scries in each jaw. none of them enlarijed. Eye larj^e, 3} to 4 J in head. Interorhital space 4 J to i\\. 

 PreojK'rcular margin membranous, with flexible ribs ending in minute spinules. Gill-rakers very long, 

 two-thirds diameter of orbit, 19 or 20 on horizontal limb of arch. 



nors;d spines high and fle.xible, the first two not noticeably thickened. Tenth spine shortest. 

 Third dors;d spine longest, 2 to 2j in head. Soft dorsal very long, its base 2j to 2^ in length. 

 The longest dorsal ray equals length of snout antl eye. Second anal spine very strong, 2^ to 2^ in 

 head. Pectoral very long and narrow, i fij longer than head, injured in most specimens. Ventrals 

 reaching to or slightly beyond vent, 1 J in head. Caudal lanceolate, the middle rays much produced, 

 as long as head. Tubes of lateral line much branched. Definite scaly sheaths along bases of dorsal 

 and anal. Basal |x>rtions of membranes of vertical fins with series of scales. 



Bright silvery, the back grayish. Lining of cheeks black, a small black blotch on upper iliird 

 of a.\il. Ventrals, anal and lower caudal rays bright orange- yellow; fins otherwise dusky-translucent. 



Rather common at Panama, where numerous specimens were secured.

BOCATUERTA RALLADA. 



A common species in the Panama market. Our material agrees with the 

 types of the species in those points which are supposed to be distinctive of this Pacific 

 form. The black streaks are conspicuous, and the second anal spine is constantly 

 shorter than the soft rays, 2J to 2g in the head. The region about the pscudobranchiie 

 is largely black. 



230. Larimus pacificus Jordan ,i- Bollman. 



Not seen by us; the type dredged by the Albatrcss in Panama Bay, Station 

 2802, 16 fathoms. It was subsequently dredged in the Gulf of California, Stations 

 3021 and 3026, 14 and 17 fathoms.

 Odontoscion xanthops GihBE.Ki (Jordan & Ever.mann, 1898, p. 1426). 



Head 3 in length; depth 3?; dors;il XII, 27; anal II, 8; pectoral 17; pores in lateral line 50. 



Head and body elongate, compressed, narrow. Dorsal and ventral outlines nearly equally 

 curved. Profile slightly depressed over front of orbits, the snout bluntish, not protruding. Jaws 

 equal, the lower wholly included, the symphysis prominent, slightly passing the prema.xillaries. 

 Mouth very oblique, the ma.xillary reaching slightly behind middle of eye, 2\ in head. Tip of ina.xil- 

 lary broad. Mental and rostral pores of moderate size, not conspicuous. A series of slender canines 

 in lower jaw, preceded by an irregular outer villiform row, most evident toward symphysis. The 

 series of canines turns inward and backward on the symphyseal protuberance, the innermost pair 

 enlarged, directed backward. Upper jaw with a series of conical teeth, similar to those on sides of 

 mandible, separated by a considerable interspace from an inner series of very small close-set teeth, 

 directed backward. Eye very large, subcircular, the longest diameter 3| in head; snout 4J; inter-
