186. Enophrys bison (Girard). 

 (Jordan and Evermann, 1898, II, p. 1938.) 



A specimen in Stanford University taken a little south of 

 Point Conception extends the range of this species southward 

 from San Francisco. It is known northward to Sitka, Alaska 

 (Bean, 1881, p. 249). 



187. Leiocottus hirundo Girard. 

 (Jordan and Evermann, 1898. II, p. 2011, fig. 732.) 

 This species reaches a length of 10 inches, and is known only 

 from the Santa Barbara Islands. It is abundant but extremely 

 local. Not seen by us. 



188. Leptocottus armatus Girard. 

 (Jordan and Evermann, 1898. II, p. 2012.) 



Very common in San Diego Bay; a haul of the seine seldom 

 failed to bring in several small ones. The largest taken was 61/0 

 inches in length. Our specimens agree with the original descrip- 

 tion and with current descriptions only when measured in total 

 length to tip of caudal. Head 2% in length to base of caudal ; 

 depth 5i/i>. The eye is greater than the interocular width, and is 

 contained 6% times in head in our largest specimens (not less 

 than interocular width, 71/2 times in head). 



This species is one of the most abundant Cottoids on the Pa- 

 cific Coast, and is known from Kadiak Island, Alaska (Bean, 

 1881, p. 251), to San Diego. It is found in shallow water, and 

 reaches a length of a foot. 



189. Clinocottus analis (Girard). 

 (Jordan and Evermann, 1898, II, p. 2012.) 

 One of the commonest fishes in the rock pools ; not seen inside 

 of San Diego Bay. The large males often develop conspicuous 

 flaps on the tips of the anterior dorsal spines. 



In life : slate color with 5 or 6 irregular black cross bars, these 

 very conspicuous in the water but much less so when the fish is
