reachiug slij^htly behind front of orbit. Mandibular teeth of equal size, 

 in a wide villiform band ; ijremaxillary band similar, preceded by an outer 

 row of short slender canines ; preorbital rather narrow, half interorbital 

 width; eyes small, obliquely set; interorbital space transversely convex, 

 its width 3f in head; a low superciliary ridge; preopercular margin with 

 a few (4 to 6) slender needle-like spines, the 3 longer ones wide sjiaced, 

 evenly radiating about the angle; margin of lower limb furnished with 

 5 or 6 minute spinous teeth, compressed, triangular, and flexible; gill 

 rakers short, slender, and about \ diameter of pupil, 6 or 7 above angle, 

 12 below ; first 2 and last 2 dorsal spines rather strong and rigid, the 

 others exceedingly slender and flexible; third spine the longest, reaching 

 beyond base of tenth spine when depressed, 1§ to If in length of head; 

 tenth spine shortest, the eleventh longer, representing the flrst ray of second 

 dorsal; distance from last dorsal ray to base of middle caudal ray equals 

 length of snout and I of eye; second anal spine long and slender, \ 

 or slightly more than \ length of head, f or i the longest anal ray; anal 

 basis but little more obli(|ue than the rest of the abdominal profile ; distance 

 from base of last anal ray to base of middle caudal ray slightly exceeds 

 distance from tip of snout to preopercular margin; caudal lanceolate, the 

 middle rays much produced, equaling distance from tip of snout to axil of 

 pectorals; pectorals short, scarcely reaching tips of ventrals, the latter 

 not to vent; outer ventral ray slightlj- produced beyond the rest. Scales 

 smaller than in 0. typicus, 5 or 6 in the vertical series between lateral line 

 and back; arch of lateral line ending over the anterior portion of anal 

 fin; head almost entirely scaled, including mandible, branchiostegal rays, 

 preorbital, and top of head forward to near extreme tip of snout ; on snout, 

 preorbital, and mandibles, the scales are cycloid. Color in spirits, nearly 

 uniform light brown, lighter below and with some silvery luster; fins all 

 dusky, the anal and ventrals black, the outer ventral ray white; opercular 

 lining dusky. Six specimens, the longest 5 inches long, from San .Juan 

 Lagoon, south of Guaymas, Mexico. (Gilbert. ) (strabo, a blinkard, from 

 the small oblique eyes. ) 



Ophioscion strabo, Gilbert, Proc. D". S. Nat. Mus. 1896 (1897), 444, San Juan Lagoon, 

 south of Guaymas, Mexico. (Type, No. 47742, U. S. N. M. Coll. C. H. Gilbert.) 



1832. OPHIOSC'IOX SIMULUS, Gilbert. 



Head 33; depth 3;?; eye 4? in head. D. XI, 26; A. II, 7; P. 18 or 19; 

 pores in lateral line 50; and smaller scales covering base of caudal fin. 

 Body more elongate and less compressed than in other species, the head 

 especially characterized by rounded outlines; jireorbitals turgid; snout 

 blunt, scarcely at all compressed, evenly rounded in all directions; top of 

 head everywhere transversely convex, not at all depressed over the orbits; 

 a scarcely noticeable depression at occiput, with the exception of which 

 the profile rises slowly and evenly to the front of the dorsal fin ; predorsal 

 region transversely evenly convex, not compressed to a ridge except iunne- 

 diately in front of first dorsal spine ; dorsal and ventral outlines about 

 equally curved, the base of anal fin but littlo more oblique than the normal 

 contour at that point. Mouth wide, broadly U-shaped as seen from below,
