with a large pore on the margm below each spine; mandibular series 

 made up of groups of small irregularly placed pores; the anterior one 

 on the median line of the symphysis large, simple, and unpaired. 



Origin of first dorsal very slightly behind a perpendicular from the 

 posterior end of subopercle ("opercular flap"); base of fin 1.6 in head; 

 fin of 10 spines, the first two with approximate bases; first spine 1.8 

 in fourth spine, which is longest, being 2.2 in head.^ Second dorsal 

 separated from first by an interspace about equal to diameter of pupil ; 

 its posterior end over base of tliird ray from end of anal; base of fin 

 3.0 in standard length; fin of 15 rays; first ray 1.2 in fifth ray, which 

 is longest, being 2.2 in head. Origin of anal about under origin of 

 second dorsal, base of fiji 2.7 in standard length; fin of 17 rays; first 

 ray 1.2 in middle rays, the fourth to thirteenth rays sub equal and 

 longest, being 2.9 in head. Pectoral base 2.7 in head; fin of 20 rays; 

 longest ray 1.1 in head, extending to level of third anal ray. Base of 

 pelvics beliind lower end of pectoral base at a distance about equal 

 to diameter of pupil; middle ray longest, outer ray shortest; length of 

 fin 2.6 in head, extending about 0.5 distance to anal origin. Caudal 

 truncate; with 9 split rays; its length 1.4 in head. Anus in front of 

 anal origm at a distance 1.5 in diameter of orbit; located just anterior 

 to the base of a short, heavy, bluntly conical genital papilla, which is 

 depressed in an abrupt pit extending 0.5 distance to anal origin. 



Head and body almost completely scaled; many small scales occur- 

 ring on anterior, dorsal, and posterior portions of eyeball. Small 

 naked areas surround the anterior nostrils, others occur between nasal 

 spines and posterior nostrils. Lips, chin, lower half of suborbitals, 

 interopercle, lower portion of preopercle and subopercle, and branch- 

 iostegal membranes naked. A narrow naked strip surrounds the 

 dorsal fins and extends along the dorsal surface of the caudal peduncle. 

 A similar naked strip occurs ventrally, extending from just anterior to 

 pelvic base to base of caudal fin. The portion of the body below the 

 lateral line, which is covered by the pectoral fins, is naked; this area 

 is separated from the ventral one by a narrow band of scales. The 

 general body scales are in the form of more or less oval, deeply 

 embedded plates from which arise V-shaped or semicircular ctenoid 

 ridges inclined posteriorly. The scales above the lateral line are very 

 irregular in size and position. Below the lateral line the arrangement 

 is more regular, with a tendency toward imbricated rows, larger scales 

 occurring near the lateral line, smaller ones ventrally. Lateral line 

 armed with 34 large scales, each in the form of a short tube with large 

 dorsal and ventroposterior expansions, the outer arch of the tube 

 with a strongly ctenoid dorsal ridge and posterior margin. A long 



' Additional specimens of this species, recently discovered in the unworked collections of Stanford Univer- 

 sity, show that the first two dorsal spines are entirely detached from the rest of the fin. Both the artist 

 and I had mistaken the lack of membrane between the second and tliird spines of the type specimen for a 

 tear in the fln. The membrane between these spines is, however, normally absent, and the figure errs in 

 this respect.
