1804. LARIMUS PACIFICUS, Jordan & Bollman. 



Head 3 (3f ) ; depth same. D. X-I, 27; A. II, 6; scales 6-50-11. Body 

 compressed, formed as in other species ; back elevated, regularly rounded 

 from snout to last dorsal ray ; ventral outline most arched anteriorly, base 

 of anal oblique. Distance from ventrals to anal more than depth of body, 

 so that the A^entrals do not reach vent. Profile of head depressed very 

 slightly before dorsal and above eyes. Snout short, 4| in head. Eye 

 moderate, equal to width of interorbital, 4 in head. Mouth rather large; 

 maxillary reaching posterior border of eye, 2J in head. Premaxillary 

 opposite middle of pupil. Width of preorbital eye. Pores of snout 

 and chin as in other species of Larimus. Preopercle with a narrow, cren- 

 ulate, membranous border; scapular scale with well-developed mem- 

 branous teeth; opercle with 3 graduated, stiff, membranous spines 

 above and another below. Gill rakers, long and slender, longest equal to 

 length of eye, about 10 + 20. Scales on head and anterior part of breast 

 cycloid; bases of membranes of fins scaly. First dorsal spine inserted 

 over base of pectorals; fourth spine longest, 2 in head. Anterior and 

 posterior soft rays of dorsal subequal, 3 in head. Second anal spine short, 

 not much over % as long as first rays, its tip not nearly reaching end of 

 last ray, 3 in head; second anal ray 2-J in head ; distance between origin 

 of ventrals and anal more than depth of body; pectorals 1 in head, 

 reaching anus; ventrals not reaching vent by almost eye, If- in head. 

 Coloration essentially similar to that of L. acclivisj silvery, with conflu- 

 ent dusky spots forming dark streaks along the rows of scales ; numerous 

 black dots from snout to caudal below lateral line; opercle appearing 

 dusky externally, because the skin lining the region around pseudo- 

 branchiye is inky black; dorsal, caudal, anal, and pectorals somewhat 

 dusky; soft dorsal pale at base, then with a dusky and pale longitu- 

 dinal streak, the distal half dusky; general coloration less yellow than in 

 breviceps and the streaks along scales more prominent. Here described 

 from the type, a specimen 5 inches long. Off coast of Colombia. 



Larimus pacificus, JORDAN & BOLLMAN, Proc. U. S. Nat. Mus. 1889, 161, Pacific Ocean, 

 off coast of Colombia, at Albatross station 2802, 8 38' N., 79 31' 30" W., between 

 Galapagos Island and Panama. (Type, No. 41168. Coll. Albatross,) 



1805. LABIMUS FASCIATUS, Holbrook. 



Head 3; depth 3; eye 4 in head. D. X-I, 24 to 26; A. II, 5 or 6; scales 

 5-49-9 to 11. Body heavy forward, much compressed, the back somewhat 

 elevated; profile convex; snout very short and blunt, 5 in head; eye 

 about equal to flattish interorbital area ; mouth large, less oblique than 

 in other species; tip of premaxillary on level of middle of pupil; maxil- 

 lary 2 in head, reaching to below posterior third of eye; lower mandible 

 with a slight knob at its symphysis, a small pore on each side of it ; teeth 

 minute, firm, in a single series in each jaw; pharyngeal teeth all long and 

 slender; the pharyngeal bones small and narrow, sub triangular ; gill 

 rakers extremely elongate, as long as eye, 12-}-24; preopercle with minute 

 cilia ; third and fourth dorsal spines about 2J in head ; preopercle with
