below the orbit and around the snout, the other vertically downward 

 behind the maxillary; a series of fringes behind the lower lip; behind 

 this a series of pores without fringes; a short straight series of pores on 

 each side of vertex ; a row of pores along the base of the dorsal fin, curv- 

 ing at front of dorsal, and terminating at upper angle of opercle; a row 

 below this, not reaching base of pectoral; the third row not reaching 

 base of caudal, but ceasing at second third of anal to about its twen- 

 tieth ray, and is anteriorly strongly curved upward to base of pectoral ; 

 2 concentric series on the abdomen, the outer extending forward between 

 bases of ventrals. The so-called "shining pores" on the sides are not 

 pores, but bright round pieces of shiny membrane, showing through a 

 translucent skin ; each of the spots has above it a pair of fringed flaps 

 with a small pore between them; the rows of flaps along dorsal and anal 

 similar, long and low, their last rays reaching base of caudal rays ; pec- 

 toral broad, somewhat pointed behind, reaching to the vertical from the 

 fifth anal ray; origin of ventrals in advance of pectorals, in distance equal 

 to length of maxillary, their tips not reaching to pectoral base; caudal 

 well rounded. Olive brown above, with coppery reflections, the belly 

 brassy-yellow; sides with irregular broad vertical cross blotches, most 

 distinct in the young ; dorsal grayish, with oblique dark bars ; vertical 

 fins sometimes margined with black; pores of lateral line bead-like, 

 shining silvery; a white space below eye, with a black crescent below it; 

 head yellowish brown, with no dark spots" on opercle and shoulder; peri- 

 toneum black. Length 15 inches. Pacific coast; very abundant from 

 Lower California to Puget Sound; living under stones, near the shore 

 northward, in deeper water southward. It makes a peculiar humming 

 noise with its air bladder, hence the name singing fish, (notatus, spotted ; 

 noted.)

2655. PORICHTHYS MARGARITATUS (Richardson). 



Head3to3f; depth 4^ to 5. D. 11-37; A. 33. Similar to Porichthys 

 notatus, differing chiefly in color. Top and sides of head and space above 

 pectorals with numerous round dark brown spots and freckles, behind 

 pectorals 6 to 8 vertical cross bars; dorsal not margined with black, 

 but with 8 to 10 black submarginal spots; anal, with the exception of a 

 few posterior rays, pale ; caudal black at base and tip ; pectorals with a 

 few dots at base and on upper rays ; a roundish white blotch below eye, 

 below this a jet-black crescent. Palatine teeth small, 1 or 2 slightly 

 enlarged. Series of shining spots arranged as in P. notatus, except that 

 the third series extends almost to end of anal, to about its thirtieth ray. 

 Pacific Coast of tropical America. This species was obtained by the Alba- 

 tross in large numbers off the west coast of Colombia, at Station 2795 at
