NOTES ON SOME CALIFORNIA FISHES, WITH DESCRIPTIONS OF 



TWO NEW SPECIES. 



BY CARL H. EIGENMANN AND ROSA S. EIGENMANN. 



Gobius townsendi sp. nov. 



Types, No. 40127, IT. S. Nat, Mas. San Diego Bay. 



Length of largest specimen ,0io m . 



Robust, compressed backward. Head heavy, blunt. Profile from 

 eye to dorsal fin straight, in front of eye rounded. 



Eye 1 in the snout, 4 in length of head, about equal to the interorbital 

 region. 



Mouth very slightly oblique, the premaxillary about on a level with 

 tlie lower margin of the eye. Teeth in a baud in each jaw, none of 

 them enlarged. 



Scales strongly ctenoid, largest on caudal peduncle. Breast and pre- 

 dorsal area naked. 



Distance of dorsal fin from tip of snout 2i— 2f iu the length. Dorsal 

 spines not filamentous, about half as high as the body. Space between 

 the dorsal fins about equal to half the length of the first ; soft rays 

 higher than the spines, about § height of body. 



Caudal truncate, about 4 in the length. Ventrals not reaching the 

 vent, 5 in the length. Pectorals little shorter than the head. 



Sides with about eight dark cross-bars which are usually interrupted 

 on the median line of the sides, a squarish dark spot thus meeting a 

 light area of similar form and size, the dark predominating on the tail ; 

 a triangular spot at base of caudal, a rather large light area in front of it ; 

 top of head and lower lip evenly punctate with dark. A black spot be- 

 fore the spinous dorsal which is usually I -shaped, a larger one between 

 the dorsals and others along the back to the caudal ; belly and lower 

 portion of sides white. Ventral and pectoral fins plain ; anal spar- 

 ingly dotted ; caudal and soft dorsal more profusely dotted, the soft 

 dorsal aud anal sometimes black posteriorly; a large black spot on 

 posterior part of the spinous dorsal ; a cluster of dots before the pec- 

 toral. 



Many specimens of this species were obtained with a skimming net 

 in tide pools and ditches on mud flats. Like the species of Griflichthys 

 it has the habit of hiding in crab holes when disturbed. 



Specimens of Gobius townsendi, about .01 m in length, have the follow- 

 ing color marks: A finely feathery pigment cell at tip of snout, one 

 between the pupils, another at the occiput and a few smaller ones before 

 it; a large cell on the back above the pectorals ; a series of three large
