as usual in this genus, with the anal spines partly detached, and provided 

 with fleshy tips. Coloration olivaceous, the body and iins everywhere pro- 

 fusely mottled and reticulated with darker ; obscure dark shades extending 

 downward from eye across, or partly across, lower side of head; head 

 without distinct spots or other sharply defined markings, except faint 

 streaks radiating from eye; no pale bars on side of head in either sex; 

 some yellowish markings on anterior part of dorsal. Length 5 inches. 

 California, from Point Concepcion southward to Todos Santos or beyond; 

 common among rocks in the kelp ; our specimens from Santa Barbara and 

 Point Loma. (Named for Charles Henry Gilbert.)

2736. HYPSOBLENNIUS GENTILIS (Girard). 



Head 3| in length (4^ with caudal) ; depth 4 (4f). D. XIII, 17; A. II, 

 19. Body rather robust, deep and compressed, the head large, very bluntly 

 and evenly rounded in profile, more obtuse and more evenly curved than 

 in H. gilberti, the snout shorter, about equal to eye, 4 in head. Mouth 

 rather small, terminal, the maxillary reaching to opposite middle of eye, 

 its length 3 in head. Teeth subequal, the hindmost on each side of upper 

 jaw shorter than the others, and a little apart from them but not forming 

 "a small canine," as stated by Girard. Superciliary tentacle long and 

 simple in the male, its edge fringed with short branchlets, its^ length 

 about 3 in head ; tentacles much smaller in the female, where they are 

 scarcely visible. Gill opening extending downward not quite to lower 

 edge of pectoral, its length (vertical) 2 in head. Lateral line with only 

 the straight anterior portion developed, not curved downward posteriorly. 

 Dorsal fins continuous, with scarcely a trace of emargination between the 

 spinous and soft parts. Dorsal spines comparatively low and flexible, 

 much less strong than in H. gilberti, the longest spines 3 in head; longest 

 soft rays If. Caudal free from dorsal and anal, If in head; ventrals If in 

 head; pectorals 1. Coloration in spirits, brown, the whole body closely 

 mottled and blotched with darker brown, so that the light ground color 

 forms, especially anteriorly, light reticulations around darker spots; on 

 the head the dark spots are small and close together, smallest anteriorly, 

 the lower parts of the head being immaculate, extending from the curve 

 of the preopercle downward, across the interopercle and branchiostegals, 

 in a sharply defined white bar (said to be golden yellow in life), edged with 

 black; behind this and parallel with it across subopercle and isthmus 

 is a similar bar, these bars present only in the males; a few pale spots 

 or bars in front of these; back with about 6 dusky cross shades, 

 below each of these is an oblong dark blotch, the anterior placed along 

 the lateral line, altogether forming an interrupted dark stripe; a simi- 

 lar dark stripe near the median line of the body, interrupted by some 

 pale blotches. Fins all blotched and spotted by light and dark colors, 

 but without distinct markings (a bluish spot in front of dorsal in life) j
