Carolina. Bathymetric occurrence : 37 to 1106 fms., but not abundant 

 in less than 100 fms. This anemone prefers muddy bottom. 



Material examined: Five specimens, 200 fms., nine miles S. W. 

 by W. of Port Basque, Newfoundland, September 1, 1926. 



Color: "Variable. The column is usually deep salmon, orange or 

 orange-red, somewhat lighter in tone than the disk. The mouth is 

 thickened and even brighter rose-red or orange than the disk, the 

 color being accentuated at the siphonoglyphs. The tentacles are ordi- 

 narily the same color as the disk, but this deeper tone is alternated 

 with pale translucent longitudinal bands; the tips are usually pale. 

 Verrill has described in detail several color variations of the species. 

 Technical description: Consult Carlgren (1891). This species is 

 closely related to Bolocera tuediae Johnston, but B. longicornis is said 

 to have distinctly longer and more numerous tentacles than tuediae. 

 B. longicornis is a large species. When expanded, it often has a 

 diameter across the tentacles of six to eight inches, with tentacles 

 two to three inches long and nearly a half inch thick. The column is 

 often two to three inches in diameter and height and is smooth, 

 lubricous, red or orange; the tentacles are very large, non-retractile 

 and easily cast off, in which event they usually leave a round aperture 

 in the disk. The tentacles each have a circular, basal muscle that 

 contracts, closing the end of the tentacle when it breaks off from the 

 disk. The tentacles are arranged in three to four submarginal rows, 

 the inner ones much the larger. They are dilated basally and tapered 

 to a blunt tip distally; longitudinal striations are conspicuous. The 

 mouth is thickened, the sulcus of the siphonoglyph is large. The 

 mesenteries are regularly hexamerous. There are no acontia or 

 cinclidae.
