35. PTEROGOBIUS DAIMIO Jordan and Snyder, new species. 
Hejid Hf in leno-th; depth 4|; deptli of cuudiil puiicle '2\ in head: eye 
4i; snout 8; maxillary 2|; D. VIlI-22; A. 22; P. 28; scales in lateral 
series 7<S, in transverse series 27. 
Body cylindrical, compressed posteriorly, the dorsal and ventral con- 
tours sloping but little to caudal peduncle; depth and width of head 
equal. Snout bluntly rounded. P>es i-ather large, dii-ectxnl laterally; 
the dorsal rim projecting- slightly, making the interorbital space some- 
what concave. Mouth oblique; jaws equal, maxillary extending to a 
perpendicular through anterior edge of pupil; lips thin. Teeth in 2 
series, slender and sharp, the inner ones minute, in a narrow band; 
outer ones much stronger, those of upper row growing successively 
smaller from before backward, the lower ones becoming larger later- 
erally to the fang-like ones on sides of jaw, then abruptly smaller, 
(iill opening not extending far forward below, the width of isthmus 
equal to distance between eyes. No elevations on inner edge of .shoul- 
der girdle. Gill-rakers on tirst arch long, ver}^ slender, and stiff. 
No barbels on lower jaw. 
Head with a few rather deeply em))edded scales on upper edge of oper- 
de and pi-eopercle; occiput with small scales; other parts of head 
naked. Bod}^ with small cycloid scales; a few- ctenoid scales below 
tip of depressed pectoral; scales on breast immediately ])ehind isthmus 
minute, similar to those on occiput. 
Dorsals separate, though close together, the 4 spines after the tirst 
greatly lengthened; when depressed their tips reach nearly to the mid- 
dle of base of dorsal; the last 2 much shorter, just reaching insertion 
of soft dorsal when depressed; I'ays growing successively longer pos- 
teriorly, the last or next to last IxMng longest. Anal similar to dorsal
