reaching slightly behind front of orbit. Mandibular teeth of equal size, 

 in a wide villiform band; preinaxillary 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 spaced, 

 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 4- 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 llexible; third spine the longest, reaching 

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

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

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

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

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

 basis but little more oblique 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 slightly produced beyond the rest. Scales 

 smaller than in O. 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.) (strdbo, a blinkard, from 

 the small oblique eyes. )

1832. OPHIOSt'IOX SIMULUS, Gilbert. 



Head 3;|; 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; preorbitals 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 imme- 

 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,
