Enumeration of the species of marine Fishes, collected at San Francisco, Califor- 

 nia, by Dr. C. B. R. Kennerly, naturalist attached to the survey of the Pacific 

 R. R. Route, tinder Lieut. A> W. Whipple. 



By Charles Girard. 



1. Chirus constellatus, G. This species comes nearest to C. guttatus, of 

 which it has the general physiognomy and structure of the fins ; but the head 

 above is less convex, and the scales very differently imbricated. Thus, whilst 

 in C. constellatus they constitute oblique series which may be traced in any di- 

 rection, the same is not the case in C. guttatus.

The ground color is greenish grey; the body at large exhibiting indistinct, 

 cloudy spots, and on the anterior and upper region, groups of black dots varying 

 in number. Similar dots are scattered over the upper part and sides of head, 

 and the pectoral fins are literally covered with them, so as to divide equally the 

 space with the ground color which make these fins appear maculated with 

 black and yellow.

Genus PORICHTHYS, Girard. 



General form and external aspect similar to Batrachus, but more elongated ; 

 its generic features will consist in the series of pores extending to the whole 

 length of body from divers regions of the head. There are neither scales on the 

 body nor membranous appendages on the margin of the jaws. Two short tenta- 

 cles in advance of the nostrils. The teeth are slender and acute; those on the 

 vomer most conspicuous. The head is smooth ; the opercle provided with one 

 spine only. 



Ohs* To this genus belong : 1st. P. porosessimus {Batrachus porosissimus, 

 Cuv. and Val.) from the coast of Brazil ; and 2d. P.porosus {Batrachus porosus, 

 Cuv. and Val.) from Valparaiso. 



3. Porichthys notatus, G. Total length about nine inches and a half, the 

 head forming the fourth of it in excluding the caudal fin. The mouth is broadly 

 cleft ; the posterior extremity of upper maxillary extending beyond the posterior 

 rim of the orbit. The teeth upon the symphysis of the lower jaw are more 

 slender and smaller than on the sides cf that bone. The smallest teeth are those 

 of the irttermaxillaries extending almost to the whole length of these bones. 

 The palatine teeth are a little larger posteriorly than anteriorly. The most con- 

 spicuous ones are observed on the vomer. Two minute and inconspicuous spines 

 constitute the anterior dorsal fin. The second dorsal is somewhat higher than 

 the anal, and the tips of the posterior rays of both of these fins reach the 

 base of the caudal, there being but a narrow space left separating these fins 

 from each other. The caudal is posteriorly rounded. The pectorals are spear- 

 shaped ; the central rays being the longest.

Upper regions purplish blue ; sides and belly silvery grey. A subcrescent 

 shaped vitta beneat.i the eye.

8. Gadus proximus, G. This appears to be a rather small species, for, amongst 

 numerous specimens brought home by several parties, and now before us, the 

 largest measures less than six inches in total length. The body is slender,
