 a color-variety of C. arctica.

-Off Saint George's Bank (S. I. Smith). This species inhabits the Gulf 

 of Mexico ; Caribbean Sea; and coasts of Florida and North Carolina. 

 It is carried northward by the Gulf Stream to the vicinity of Saint 

 George's Bank, and is, therefore, like the two following, likely to occur 

 occasionally at Nantucket and Martha's Vineyard.

This species was originally described and figured from mutilated 

 specimens taken under the equator in the Atlantic Ocean, and seems 

 not to have been seen by later writers. Mr. S. I. Smith has apparently 

 rediscovered this interesting species off Saint George's Bank. 



The specimen obtained by him, while on the United States Coast- 

 Survey steamer Bache, in 1872, is not quite perfect, but agrees pretty 

 nearly with the descriptions and figure cited. 



The body in the alcoholic specimen is elevated, bell-shaped, rounded 

 above, with a marked constriction toward the border ; transparent, the 

 inner cavity showing through as a large, conical, dark reddish brown 

 spot, with the apex slightly truncated. Border deeply divided into six- 

 teen long, flat lobes, which are of nearly uniform breadth throughout, 

 and slightly rounded, or sub-truncate, at the end ; the edges and end 

 thin and more or less frilled ; the inner side with two sub-marginal 

 carinse. Eyes inconspicuous, but small bright red specks are scattered 

 over the marginal lobes. The intervals between the lobes are narrow 

 and generally smoothly rounded, without distinct evidence of the exist- 

 ence of tentacles, except that, in one of these intervals, there is a small 

 and short papilliform process, with brown pigment at the base. The
