CENTRISCIDAE. 

 Centriscus scutatus Linne. 

 One without data. 



Centriscus strigatus (Giintlier) 



One without data. Aeoliscus Jordan and Starks, based on this 

 species, would appear only of sub-generic rank. 



PEGASIDAE. 



Parapegasus natans (Linne) 



Padang, Sumatra. 



SYNGNATHIDAE. 



Entelurus aequoreus (Linne) 



Osphyolax pellucidus Cope, Proc. Acad. Nat. Sci. Phila., 1875, p. 450, PI. 

 25, figs. 1-4. Open Atlantic Ocean. 



No. 860, A. N. S. P., type of 0. pellucidus Cope. Duncker has 

 correctly placed this nominal form as a synonym of Syyignathus 

 aequoreus Linne* and although the type has been overlooked until 

 now, its identity is unquestioned. It is, however, still in good 

 preservation and shows: Rings 29+62?; D. 37, on 8+3 rings; head 

 4f to vent; vent about opposite last third in dorsal base. Length 

 283 mm. On the basis of the very general type locahty this species 

 could hardly be included in the North American ichthyfauna. 



Cope gives "thirty-one transverse rows of scuta" though my 

 count shows the above formula. Also he says '' dorsal radii sixteen, " 

 his figure showing 18, whereas there are actuallj^ 37. Also he gives 

 "total length 23 m.," while his specimen is actually 283 mm. long. 



Nerophis maculatus Raflnesque. 



Rings 21 or 22 +50 to 67; D. 21 to 25, on 2 or 3 +5 rings. Three 

 from Italy. 



Gastrotokeus biaculeatus (Bloch) 

 Bacon and PhiHppines. 



Doryrhamphinanim lineatum (Valenciennes) 



Santo Domingo, W. I. Duncker sets aside Doryrhamphinarum 

 Kaup^. Kaup included Syngnathus heterosoma Bleeker monoty- 

 pically, and such is here acknowledged as its type. It therefore 

 supersedes Micro-phis as used by Duncker.
