464 NEW SPECIES OF FISHES FROM CALIFORNIA. 



cells somewhat removed from the one above the pectorals ; and another 

 series of six cells on the back somewhat removed from the series of 

 (luce; a dark line extending from top of snout to origin of anal and 

 continued as a series of large dark pigment spots to near the caudal. 

 A few spots on the auditory capsule ; a series of spots along upper por- 

 tion of the air bladder to near the caudal; a transparent bar near base 

 of caudal. Tip of lower jaw black; sides tinged with yellow. 



In the specimens of this species of about .0L m there arise on the head 

 and sides hyaline threads corresponding to the mucus pores. These 

 threads have no resemblance to hairs or bristles with which these 

 structures have sometimes been compared. They are most numerous 

 on the tail. There are 33 in the lateral line. 



We have dedicated this species to Mr. C. II. Townsend, naturalist of 

 the U. S. steamer Albatross. 



Lepidogobius gilberti sp. now 



Types, No. 40128, U. S. Nat, Mus. San Diego Bay. 



Length of largest specimen .055'". 



Head 3-3J (3§-4 in total); depth 5-5J (6-7); D. V. 15 to 17; A. 14 

 to 16; Br. 5. -Vert. 15 + 19. 



Form elongate, compressed. Head long, subcouical, about as high 

 as wide; its width 2^ in its length. Profile nearly straight from eyes 

 to spinous dorsal, decidedly decurved in front of eyes. Eye entirely 

 above the premaxiilary level, 1 in snout, 4i in head, one-half in in- 

 terorbital. 



Mouth slightly oblique; maxillary extending to below middle of 

 eye, the lower jaw slightly includad. Teeth villiform, in a broad band 

 in each jaw, the outer series of the lower jaw somewhat enlarged. 



One, rarely two, dermal flaps on inner edge of shoulder girdle. 



Scales cycloid, imbedded, very small ; head, nape, and breast naked. 



Distance from tip of snout to insertion of spinous dorsal 2f in the 

 length. Highest dorsal spine about two-fifths the length of the head; 

 soft dorsal rays lower. Interdorsal area about half the orbital diame- 

 ter. Tip of last dorsal ray not reaching base of caudal. 



Caudal broad, and rounded when expanded. 



Anal similar to the soft dorsal fin. Ventral fins large, nearly reaching 

 the vent in specimens .045'" long. Pectorals usually shorter than the 

 ventrals. Color in life, sand color; head and body with small rust- 

 colored spots which are dotted with black, the punctulatious forming a 

 more or less regular network. Dorsal fins hyaline at base, bright rust- 

 colored above and rather broadly margined with white, everywhere 

 black punctate except on the margins; about three groups of black 

 dots on each ray, giving a barred appearance to these fins. Caudal mar- 

 gined with white, upper and lower parts of the fin rust colored, median 

 portion dark gray; about 5 wavy, rust-like, vertical bars; entire fin 

 dotted with black except its margin. Anal fin hyaline at base, sparsely
