NEW STALKED CRINOIDS FROM THE EASTERN COAST 
OF NORTH AMERICA. 
By Austin Hopart Crark, 
Of the United States Bureau of Fisheries. 
In 1885 Prof. A. E. Verrill mentioned that “a fine species of 
stalked crinoid, belonging to the genus Lenthocrinus, was dredged 
in 1884 in 2,021 « fathoms, off Chesapeake Bay.” Later, he referred to 
the specimen as a species of Bathycrinus “near B. gracilis Wyville 
Thomson.” No further mention is made of it, and the record and 
specimen appear to have been forgotten. Recently, however, the 
example has been sent to Washington, together with a large number 
of other crinoids, from New Haven, where I have had an opportunity 
of examining it. It proves to be a remarkably fine specimen of a new 
species of Bathycrinus, allied to B. aldrichianus, from the tropical 
mid-Atlantic, but quite different from anything heretofore known. 
The genus Bathycrinus was first discovered off the coast of Europe 
‘by the Porcupine, and has since been found abundantly in the north- 
east Atlantic, and recorded from the middle Atlantic, Antarctic 
Ocean, East Indies, mid-Pacific, off southern Japan, and off Kam- 
chatka, in the last four localities only within the past year. The 
first definite record for the genus on the American side of the At- 
lantic was published in January, 1908, when a small species, B. carib- 
beus, was described from the West Indies. It is therefore with con- 
siderable satisfaction that I am able to add another species of this 
especially interesting genus to the marine fauna of the American 
coast.
