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

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

 thus admitted is not extremely large.

TH£ OCCIJBBENCE OF BIPPOC AJTIPUS ANTIQUOBUIH, OB AIV 

 AIiIilED FOBm, Onr SAINT OEOBOE'S BANKS. 



By O. BROWIV GOODE. 



A specimen of Sippocamirus, measuring about five inches, was pro- 

 cured by the United States Fish Commission from a mackerel schooner^ 

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

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

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

 rently not beiug used for preheusion. This specimen agrees very closely 

 with H. antiquorum as described by Giinther, and is provisionally referred 

 to that species 5 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. guttulatus^ Cuv. 



H. antiquorum is, then, an addition to the fauna of Eastern North 

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

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

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

 collected in Bermuda in 1872 and 1877 in company with H. guttulatus. 



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

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

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

 proposed by DeKay, but his description aifd figure refer to a form more 

 nearly resembling that now under consideration. 



The following notes were taken from tlie fresh specimen, the colors 

 while it was living : —
