* These proportionate measurements, as taken from the " Histoire Naturelle des Poissons ", doubtless 

 have reference to extreme length to end of external caudal rays. In this genus, however, the differenco 

 thus admitted is not extremely large.

A specimeu of llippocampn.s, measuring about five inclies, was pro- 

 cured by the Uuited States Fish Commission from a mackerel schooner, 

 which had captured it, in company with a school of mackerel, on Saint 

 George's Banks, in August, 1873. It was kept alive for some days, and 

 an interesting fact was observed witl) regard to its habits, its tail appa- 

 rently not being used for prehension. This specimen agrees very closely 

 with H. antiquorwn as described by G linther, and is provisionally referred 

 to that species; it does not agree with the description and figure of H. 

 hudsonius, DeKay, a species which has never been accurately defined, 

 and which may prove identical with H. giittulatusj Cuv. 



II. antiquonim is, then, an addition to the fauna of L^asteni North 

 America. The geographical range of the species is very wide ; it has been 

 recorded from the English coast, the Mediterranean nt Malta and other 

 points, Fernando Po, Japan, and Australia. Several specimens were 

 collected in Bermuda in 1872 and 1877 in company with R. (juUulatus. 



A specimen received by Storer from Holmes'S Hole was, in his first 

 report, referred to H. hrevirostris, Cuv., which is synonymous, according 

 to Giinther, with If. antiquorum. Storer afterward adopted the name 

 proposed by BeKay, but his description and figure refer to a form more 

 nearly resembling that now under consideration. 



The following notes were taken from the fresh specimen, the colo;-5
