FISHES OF NEW YORK 379 



Three individuals of Mullus were captured in a seine at 

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

 York aquarium, where the}' are now (Nov, 30, 1897) in good con- 

 dition and feed freely on shrimp. As the fish are living, it is 

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

 agree 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. 



Recent examination of one of the specimens above referred to 

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

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