Note. Dr. G. Duncker, who made a thorough study of 

 the genus Hippocampus, the results of which have not yet 

 been published, had the great kindness to give us information 

 about the validity of the above species. We agree with him, 

 that GONTHER and most later authors were wrong in uniting 

 H.kiula with H. guttulatus Guv. from the Atlantic. Lastnamed 

 species has more dorsal rays (D. 18 — 22, generally 19) and 

 more caudal rings (33 — 40, generally 38).
