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

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

 the fin broadly mai'gined all around with white. Many specimens, males

1112. SIPHOSTOMA CALIFORNIENSE (Storer). 



(Great Pipefish.) 



Head 6^ to 8+ in total lenjjth; D. 39 to 46; rings 20 to 21 -(-47 to 49. 

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

1113. SIPHOSTOMA GRISEOLINEATUM (Ayres). 



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

 but difl'ering 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 -f- 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, {grisrun, gray ; Uneatus, 

 lined.)
