Syng^nathus elucens Poey. 



Marquesas and Big Pine Keys, Florida. Rings 16 to 18+28 to 

 33 , D. 28 to 30, in 3 or 4 +4 or 5 rings. Length 55 to 1 17 mm. 



Syngnathus schlegelii Kaup. 



Yokohama and Otaru, Japan. Rings 19 or 20+40 to 43; D. 34 

 to 39, on 1+8 to 10 rings. Largest 229 mm. 



Syngnathus californiensis Storer. 



S. giiseclineatus Ayres, Proc. Cal. Acad. Sci., 1854., p. 14. San Fran- 

 cisco Bay. 



No. 835, A. N. S. P., type of S. griseolineatus Ayres. In 

 very poor condition. Other examples from Monterey and Cali- 

 fornia, and Willamette River, Oregon. Rings 19 to 21 +42 to 52; 

 D. 37 to 44, on 1+8 to 10 rings. 



Jordan and Evermann say S. griseoUneatus Ayres differs in a 

 somewhat shorter snout, number of dorsal rays and rings, more 

 keeled snout and dorsal covering or 1+9 rings. My material all 

 appears to be S. californiensis and the type of S. griseolineatus 

 has at least 18 body rings and not one of the other specimens show 

 less than 19. 



Syngnathus pelagicus Linu§. 



Many examples; 5 labeled "Delaware Bay"; N. Lat. 24° 21' West 

 Long. 34° 32'; N. Lat. 23° 20' West Long. 57° 29'; N. Lat. 23° 59' W. 

 Long. 37° 59'; Lake George, Florida. Rings 16 or 17+29 to 32; 

 D. 28 to 33, on 2 to 4+4 to 7 rings. All this material is charac- 

 terized by the vertical white lines on the trunk, one on each ring 

 inferiorly. 



Jordan and Evermann place this species in their key under the 

 group with "dorsal covering 4 or 5 body rings" and immediately 

 below as "on 1+9 rings." In only one example (Lake George) 

 have I found the dorsal on 4+4 rings. I cannot find Siphostoma 

 scovelli Evermann and Kendall is distinct, and in fact its alleged 

 distinctions are covered by the variations in my material. 



Syngnathus fuscus (Storer) 



Massachusetts, New Jersey, Delaware, Maryland and Virginia. 

 Also one labeled "Neuse River, North CaroHna." Rings 17 to 20 

 +36 to 40; D. 32 to 40, on 4 to 6+4 to 6 rings. Largest 240 mm. 



Syngnathus mackayi Swain and Meek. 



Marquesas and Big Pine Keys, Florida. Rings 17 or 18+31 to 

 35; D. 29 to 31 on 1 to 3 +5 to 7 rings. Largest 160 mm.
