' Siphostoma mackayi Swain & Meek, Proc. U. S. Nat. Mus., 1884, 239; Key West. In 

 this paper is a very useful analysis of the characters of the species of this genus, supple- 

 mentary to a paper on the same subject by Mr. Swain, Proc. II. S. Nat. Mus., 1882, 307.

3 DORYRHAMPHUS Kaup. 



(Eaup, Lophobranchii, 1856, 54 ; type Doryrhamphus exoisus Kaup. ) 



This genus differs from Siphostoma chiefly in the position of the egg-pouch of the 

 male, which is under the abdomen instead of the tail. The angles of the body are 

 strongly ridged. Tropical seas. (Jopt), lance ; pa//0o?, snout.) 



Doryrhamphus californiensis Gill. 



Yellowish brown, with a black streak from snout to axil. Snout half as long as 

 head, its crest formed of about ten irregular teeth, behind which are two others. 

 Double frontal crest well serrated. Ridge under orbit unarmed, but on side of snout 

 it is well serrated. Chin prominent but unarmed. Pectorals as long as opercle. 

 Caudal as long as snout. D. "25. Rings 20-f 16. Cape San Lucas ((?i77). The types 

 are lost and no specimens have been since recorded. 



(Gill, Proc. Ac. Nat. Sci. Phila., 1862, 284: Doryichthys californiensis Giinther VIII, 

 186.) 



■•The family Hippocampidce should be, apparently, reunited with the Syngnathidae. 

 I here omit Hippocampus hippocampus ( = heptagonus Raf. ; antiquorum, Leach), not be- 

 lieving that that species has been actually taken in American waters. 



*The reasons for using the name Macrorhamphosus for this genus instead of Centrie- 

 cm are stated in Proc. U. S. Nat. Mus., 1882, 575. The original type of Cent'riscus is 0. 

 scittatits. 



A valuable discussion of "the mntpal relations of the Hemihranchiate fishes" is 

 given by Dr. Gill, Proc. Ac. Nat. Sci. Phila., 1884, 154.
