anterior profile, the more rounded snout, the vertically instead of 

 horizontally elliptical posterior nostril, the somewhat longer 

 gill-rakers, the larger eye (4.1 instead of 5.0 to 5.5 in head), 

 the shorter interspace between anus and anal fin (5.25 instead of 

 2.9 to 3.5 in head), and the number of soft dorsal rays (28, not 

 24 or 25). From vermicular is it may be distinguished by the much 

 longer second dorsal spine, much shorter and weaker second anal 

 spine, the much less elevated anterior profile, shorter pectorals, 

 shorter distance between anus and anal, the lower curve of the 

 lateral line, and numerous other characters. 



Holotype: A specimen 102 mm. long to caudal, from Avalon, 

 Santa Catalina Island, California; secured from the Avalon 

 Aquarium; Cat. No. 55053, Museum of Zoology, University of 

 Michigan. Only one specimen known. 



Description: Dorsal, XI, 28; anal, II, 7; pectoral, 18; pores 

 in lateral line, 50; head, 3.61; depth, 3.52. 



Body comparatively elongate and little compressed; head 

 evenly rounded; dorsal contour evenly convex from snout to 

 dorsal fin, much more strongly curved than ventral contour; 

 predorsal region behind occiput compressed to a ridge. Eye, 

 4.1; interorbital slightly convex, a little wider than eye; sub- 

 orbital flattish, two-thirds as wide as eye; mouth rather narrow, 

 its width less than the length of the upper jaw, which extends to 

 below middle of pupil, 2.75 on head; mouth little oblique, slightly 

 overhung by the bluntly , rounded snout. Teeth in villiform 

 bands on jaws, the outer premaxillary series composed of semi- 

 depressible canines, which, near the symphysis, are about one- 

 eighth as long as eye. Snout 3.6, with conspicuous slits and 

 pores; anterior nostril round, much smaller than the vertically 

 elliptical posterior nostril; no nasal flaps. Preopercle armed with 

 about 29 serrations, rather small, not much enlarged at angle, 

 becoming minute at both extremes of series (the serrations evi- 

 dently were originally bony, but preservation in strong formal-
