332 FISHES PROM MAZATLAN. 



pale; tlu' last spines and firsl soft rays of dorsal edged with black. 

 No tract' of black lateral spot. 



This species is closely related to Lutjanus Tcasmira Forskal = Lutja- 

 uiis bengalensis (Bloch) Bleeker, a common species of the East Indian 

 sens A .specimen of the latter, lo inches long (from Swatow, China 

 Adrie M. Fielde, collector) differs in the following respects: Body 

 deeper (depth 2-|); scales smaller (8) 12-62-22; the back more elevated 

 and the profile Steeper; snout..') in head; preorbital6; maxillary, 

 Second anal spine .'!',. 



In L. kasmira the lower lateral band is wanting, and there is a vaguej 

 dark lateral blotch larger than eye on the side. The bands in L. has- 

 mira are less sharply defined, the bine center of each is more than twice 

 as wide as the dark border, and the whole band is narrower, its width 

 one-third to one-fourth that of the golden-brown interspaces. There is 

 no bine median dorsal streak. In other respects the two species agree 

 closely. 



17. Heros bsa-ii, ap. uov. 371 15 (5), 37165 (2). From Rio Presidio, Mazatlan. 



Head, 3 in length: depth, 21; D XVI, 11, A. V, 8. Scales, 4A-30-12. 

 Length of largest specimen, 5| inches. Body oblong, compressed, the 

 back moderately elevated ; profile gibbons at the nape, depressed and 

 concave above eves, thence straight to tip of snout, which is short and 

 rather sharp; snout, 3 in head; eye small, 4.] in head, LI in the slightly 

 concave interorbital space. Lower lip moderate, its fold continuous, 

 without frenum. Teeth moderate, maxillary short, 3 ; V in head; lower 

 jaw slightly projecting; preorbital, lAin head; G rows of scales on cheeks; 

 edge of preopercle oblique, straight, entire; gill rakers very short, 

 thickisli. Dorsal spines low, the longest a little shorter than snout, 

 sott dorsal and anal elevated, pointed, their tips reaching a little past 

 base of caudal, the longest ray about 1 ; ' 5 in head; bases of soft dorsal 

 and anal somewhat scaly ; caudal snbtrnncate. Ventrals reaching 

 beyond pectorals, l.'j in head ; pectorals, LL Color olive, the centers of 

 many scales on sides of body and head paler in some specimens ( 2 ?), 

 and darker in others { 8 '.) ; sides with traces of about 8 obscure dark 

 cross bars, which are about as wide as the interspaces. A faint pale 

 streak from below eye lo maxillary; an obscure black spot, most dis- 

 tinct in young and rather larger than eye, on lateral line and below 11th 

 and 12th dorsal spines ; a similar spot at base of caudal, just above lat- 

 eral line. Fins olivaceous, the dorsals, caudal, and anal with roundish 

 spots of dark olive. Lower fins dusky. 



This species is named for my friend, Dr. Tarleton II. Lean, Ichthy- 

 ologist, U. S. Fish Commission, in recognition of his researches in 

 American ichthyology. 



It seems well separated from all other Mexican species of which I 

 find descriptions. .V specimen from Lake Nicaragua, which I suppose 

 t<« be //. basil, iris Gill, much resembles //. beani in form and in colora-
