FISHES OF NEW YORK 379 



Three individuals of M ii 1 1 ii s were captured in a seine at 

 Sandv Hook N. J. Oct. 8, 1897, and brought alive to the New 

 York aciuariuni, where the}' are now (Nov. 30, 1897) .in g'ood con- 

 dition and fcM'd freely on shrimp. As tl>e fish are living, it is 

 uncertain whether or not they are M. a u r a t u s ; but they 

 agiMM^ in the main with the description of that species. Their 

 endurance of water at a temperature of 50° F. is unexpected. 

 Fishermen at Sandy Hook reported that large numbers were 

 seen there in September and October 1897. 



Kecent examination of one of the specimens above referred to 

 (No. 48796, U. S. National Museum) shows its entire agreement 

 with the type of ]\[ u 1 1 u s a u r a t u s .
