94 NEW FISHES FROM PACIFIC COAST — GILBERT. 



intervening rays, a space without rays present, equaling diameter of 

 pupil. The lower lobe consists of four rays, the longest three fifths 

 head, inserted under preopercular margin. The main portion of the 

 fin consists of about fifteen rays and is but slightly longer than the 

 lower lobe; dorsal beginning behind middle of pectorals, its distance 

 from tip of snout 4^ in length; distance of origin of anal from tip 

 of snout equaling one-third standard length. 



Vent under base of upper pectoral rays, but wholly behind base of 

 lower lobe of pectorals, its distance from tip of snout equaling length 

 of head and equaling also its distance from origin of anal. No trace of 

 ventral disk or fins. 



D. 58 ; A. 53. 



Color: Light rose-red, the fins and head largely jet black. Abdomen 

 behind vent blackish. Peritoneum and lining membranes of mouth 

 and gill-cavity jet black. 



A single specimen, 5^ inches long, from station 2919, in 984 fathoms. 



54. Gobiesox pinniger sp. nov. 



Head 2f to 22 in length ; width of body 4^; of head, 3 in length. D. 

 16 or 17; A. 8 or 9. 



Interorbital width 3^ in head ; eye half interorbital width ; width of 

 mouth If to If in head. L. 2^ inches. 



Teeth in upper jaw conic, acute, in several series, the anterior row in 

 front enlarged, unequal. In lower jaw the teeth mesially in two dis- 

 tinct series, those in middleof anterior row narrow entire incisors, those 

 laterally conic, canine-like. 



No evident opercular spine. 



Disk about as broad as long, its length about that of head. 



Front of dorsal varying in position, about midway between snout 

 and base of caudal, its length about half that of body. Vent nearly 

 equidistant between disk and front of anal, the base of latter 3^ to 3f 

 in body. Caudal I^ to If in head. Pectorals about one-third of head, 

 with a distinct fold at base. 



Color variable. Anteriorly usually with reticulating dark lines sur- 

 rounding yellowish spots. A narrow dark streak forward, one down- 

 ward, and one backward from orbit. Below dorsal fin about six dark 

 bars running obliquely downward and backward, these sometimes in 

 greater number, frequently more or less irregular and interconnected, 

 often divided by vertical streaks or series of dots. Body sometimes 

 light in spirits, without distinctive markings. Vertical fins usually 

 dusky, narrowly margined with white, sometimes lighter with dark 

 margins. 



Abundant in the Gulf of California. Specimens taken at Puerto 

 KefugiOj Angel Island, San Luis Gonzales Bay, and La Paz.
