very uarrow blue margin. Pectorals yellowish. Ventrals yellowish- 

 olive. Vertical fins otherwise with color of sides. 



This brilliant species is extremely abundant at Clarion, Socorro, and 

 San Benedicto Islands. It reaches a length of about 7 inches. 



30. Gobius zebra sp. uov. 



Body not elongate, the snout short, the mouth oblique, with maxil- 

 larj" reaching below middle of orbit. 



Head 3 in length ; depth 4J. D. VI, 11 or 12 ; A. 9. L. one-half 

 inch. 



Mouth small, the maxillary 2i in head. Interorbital space very nar- 

 row. Eye 31 in head. Teeth in upper jaw in a narrow band or double 

 series, the outer row enlarged and spaced. Lower jaw apparently 

 with a single series, similar to the outer row in the upper jaw. 



Scales cycloid, large, wanting on nape and a narrow strip along base 

 of spinous dorsal. 



Color: Cherry-red, head and sides with fifteen blue cross-bars, a 

 little narrower than interspaces, encircling body posteriorly, lacking 

 for a short distance on belly and under side of head. On upper side 

 of head and nape these bars run obliquely forwards and downwards, 

 but are elsewhere vertical. On middle of each interspace a very nar- 

 row blue line, becoming indistinct on lower part of sides. On cheeks 

 the blue bars are connected by narrow cross-lines forming blue reticu- 

 lations surrounding round spots of the ground color. 



Two specimens from Station 2,989, in 36 fathoms. 



31. Gobius dalli sp. nov. 



Resembling species of ^Mieroffobins. With short compressed body, 

 high head, and moderate, very oblique mouth; upper pectoral rays 

 normal ; scales ctenoid, of moderate size ; anterior dorsal spines much 

 produced. 



Head 3| in length -, depth 4^. D. VI-17 ; A. 14. Lat. I. 40. 



Mouth very oblique, the maxillary reaching vertical from front of 

 pupil, 2J in length of head. Snout short, two thirds diameter of orbit, 

 which is 3 in head. Jaws with an outer series of long, distant, canine- 

 like teeth, and an inner series or a narrow band of minute teeth. 



Dorsal spines six, the two anterior greatly elongate, not free, in our 

 largest specimen extending beyond middle of soft dorsal. Membrane 

 from last dorsal spine reaching to, or nearly to, base of first soft ray. Soft 

 dorsal rather high, the fin long. Caudal rounded, less than length of 

 head. Ventrals free from belly, fully united. Pectorals short, the 

 upper rays not free nor silk-like. 



Scales of moderate siz(^ ctenoid, covering entire trunk, with possible 

 exception of the nape. The scales are readily caducous, and are lack- 

 ing on nape and frequently on anterior third of body in our specimens.
