221. Hypsoblennius gilberti (Jordan). 

 (Jordan and Evermann, 1898, III, p. 2386.) 



Taken in abundance in tide pools on the ocean side of Point 

 Loma, and at San Pedro ; not found in the open bays. 



The species may be known from Hypsoblciniius (jcntilis by 

 the almost straight profile of head from tip of snout to between 

 eyes, and by the multifid tentacle over eye. The sexes do not 

 greatly differ; the tentacle of the male is somewhat longer than 

 that of the female, but the tentacle of the latter is much longer 

 than in the female of llypsohlennius gent His. The two anal 

 spines of the male are provided with fleshy tips. It is known 

 from Santa Barbara (type locality) to Todos Santos Bay, Lower 

 California (Smith, 1883, p. 235). It does not exceed six inches 

 in length. 



222. Hypsoblennius gentilis (Girard). 

 (Jordan and Evermann, 1898, III. p. 2387.) 



Common at San Diego and San Pedro in the open bays; no 

 specimens seen in rock pools with Hypsohlennius gilbert i. This 

 species may be known from Hypsoblennius gilberti by the rounded 

 profile of head from tip of snout to above eyes, and by the simple 

 fringed tentacle above each eye. 



The males have the two spines of anal partly free and pro- 

 vided with fleshy tips, and the supraorbital tentacle long and 

 slender. Color in life : anterior half of body and head thickly 

 set with sharp-cut round spots of black or dark brown, narrowly 

 separated from each other by fine olive green lines of the ground
