transversely concave. Color light olive or grayish, the back and upper 

 part of sides mottled with brown, this frequently taking the form of 

 rather wide, ill-defined bars ; interspace between bars often marked with 

 a narrow, pearly- white crossbar ; on lower portion of sides of tail, a 

 brown streak between each two plates ; dorsal light, its basal portion 

 with oblique brown streaks and spots ; central portion of caudal dusky, 

 the fin broadly margined all around with white. Many specimens, males 

 and females, from Albatross Stations 3027 and 3028, in the Gulf of Cali- 

 fornia; the largest 8i inches long, (carinatus, keeled.)

1112. SIPHOSTOMA CALIFORNIENSE (Storer). 



(GREAT PIPEFISH.) 



Head 6 to 8 in total length D. 39 to 46 ; rings 20 to 21 + 47 to 49. 

 Trunk robust. Snout very long, 1 to If in head, with median ridge 

 above and below. Occiput and nuchal plates not carinated in adults. 

 Dorsal shorter than head, covering 1 + 9 rings ; distance to dorsal 2f in 

 length ; pectorals as long as high, equaling in length the diameter of 

 eye ; caudal pouch of males covering 21 to 25 rings, its length 3 in total. 

 Color in life olivaceous, varying to brownish red ; yellowish below ; head 

 and body variously marbled and speckled with whitish, the marking 

 posteriorly taking the form of short horizontal grayish streaks, especially 

 distinct on the top of the head; anteriorly often forming narrow bars. 

 Snout variable, sometimes not longer than head. Pacific Coast of the 

 United States from Santa Barbara northward ; common south of San 

 Francisco. Much larger than the other American species, reaching a

1113. SIPHOSTOMA GRISEOLINEATUM (Ayres). 



D. 36 to 41 ; rings 18 to 19 -f 39 to 42. Closely allied to S. calif orniense, 

 but differing in a somewhat shorter snout, in the number of dorsal rays, in 

 the number of rings, in its size, in the snout being slightly more keeled, 

 and in the dorsal covering 0-1 + 9 rings. Pacific Coast of the United 

 States, from Puget Sound to Monterey, rather less common than the pre- 

 ceding species, and somewhat smaller in size, (griseus, gray; lineatus, 

 lined.)
