angle of preopercle overlapping interopercle entirely at one place; 

 breadth of velar flap measured from tip of lower jaw half diameter of 

 eye; teeth small, in a band 4 or 5 series wide anteriorly, narrowing 

 on either side, none enlarged, rows subequal; gill rakers fine and 

 longer than usual, 2 J to 3 in eye. 



First dorsal inserted in advance of pectoral base, its rays long and 

 reaching to sixth of second dorsal; latter nearly one and one-half 

 times as high anteriorly as posteriorly, longest ray one-half to two- 

 thirds those of first dorsal; dorsal termination above third from last 

 anal ray, which is nearly depth of caudal peduncle from end of fleshy 

 portion of tail; ventrals extending nearly to or slightly beyond anus; 

 pectoral rounded. 



Upper lateral line extending slightly beyond last dorsal ray, over- 

 lapping lower lateral Hne with eight of its scales. 



Scales very roughly ctenoid, even on dorsal surface of head; 

 present everjrwhere save on lips, snout, and lower jaw; extending to 

 between anterior border of eyes on interorbital space, to end of max- 

 illary on cheeks, not present on interopercle and limbs of preopercle; 

 scales on dorsum of head as large as those on flanks, as are those on 

 opercle; on cheeks and space between occiput and dorsal somewhat 

 smaller; area before and between ventrals scaled. 



Color pattern striking; four pairs of irregular dark stripes trans- 

 verse to body, inclined posteriorly somewhat above lateral line, 

 and continued on dorsal as black spots; these fading ventrally; a 

 dark patch in center of caudal peduncle; a yellowish brown stripe as 

 wide as pupil running from occiput in a curve to median line of body 

 and thence to center of caudal; no color pattern observable on head; 

 first dorsal dusky; second with indications of longitudinal stripes, 

 and black spots continued from body stripes to half height of rays; 

 anal appears to have dusky markings and clear margin; pectoral with 

 diffuse blotch across upper part of base; ventrals clear. 



Named for Dr. D. S. Jordan, of Stanford University. 



The striking features of this species are the following: A high first 

 dorsal; large roughly ctenoid scales on head; black spots on second 

 dorsal; and long, fine giU rakers. It is probably most closely related 

 to Nototlienia longipes and N. tessellata, but is very distinct from 

 either. 



Our specimens differ from the description given by Regan of 

 Nototlienia ramsayi in the following characters: The scales do not 

 extend as far forward as the nostrils in any of our numerous speci- 

 mens and they are very large on the interorbital space, three of them 

 forming a transverse series from eye to eye; and the lower jaw is 

 slightly longer. From his plate the following differences may be 

 noted, although they may possibly not hold when the species are 

 directly compared: The preopercle overlaps the interopercle entirely
