HISTOKY OF THE ATLANTIC CITY SPECIMEK. 



Regarding the iinding of the Atlantic City specimen and its exterior and 

 gross anatomy, notliing has been published except brief references by Sir William 

 Turner in 18S9'' and Dr. Glover M. Allen in 1906, '^ taken from a newspaper report 

 of a communication made by myself before the Biological Society of Washington 

 in 1889. On that account a somewhat detailed statement regarding it will be 

 made in this place. 



This individual (PI. 41, figs. 1, 2) was a male, 12i feet long. It was observed 

 by the crew of life-saving station No. 28, near Atlantic City, New Jersey, on the after- 

 noon of March 28, 1889. It had come inside the bar whi'ch skirts the coast at this 

 point, and was apparently unable to find its way out. It was captured with some 

 difficulty, after being womided in the throat, and was dragged up on the beach near 

 the station. Tjator in the day it was carried to the skating rink of Messrs. Johnson 

 & McShea, at Atlantic City, where it was exliibited until Monday, April 1. On 

 the next morning it was sent by express to Washington. 



I examined it for the first time in Atlantic City on March 29. It was then 

 lying on the floor of the skating rink in such a position that the under surfaces were 

 concealed, and, as the teeth were not visible, I mistook it for a female. Upon .its 

 arrival in Washington, however, where it could be examined under more favorable 

 circumstances, it proved to be a male. The following measurements were taken 

 from the fresh specimen:
