218 A. E. Verrill — New Actinians. 



Anthopleura Japonica Ver., sp. no v. Figure 39. 



The body is contracted in alcohol to an ovate form, the disk 

 and tentacles being concealed and the base reduced to a small 

 concave area, but it is somewhat mutilated. 



Above the middle the wall is covered with fine transverse 

 wrinkles and has unequal vertical rows of concave adhesive 

 suckers. Higher up these are replaced by hollow, round or 

 conical verrucae, and then by more prominent papillae, the 

 upper ones becoming lobulated more or less on the outer and 

 under sides by small papillae. Of marginal papillae there are 

 48 rows, larger and smaller, but of these rows only about 36 

 are prolonged downward by rows of stickers. Some of the 

 marginal papillae seem to be perforated. The mouth has two 

 siphonoglyphs. Tentacles about 96, rather stout, tapered, 

 arranged in three or more crowded rows. Probably they were 

 rather elongated in expansion. The sphincter muscle is en do- 

 dermal, rather large, ovate in section, sharply circumscribed. 



Mesenteries are in four regular hexamerous cycles, all much 

 thickened ; those of the 3d and 4th cycles are successively nar- 

 rower and smaller; 12 pairs are perfect and nearly equal, 

 including two pairs of directives. All bear strong, thickened, 

 pleated longitudinal muscles ; those of the perfect pairs extend 

 over more than two-thirds of their breadth and are thickest 

 about the middle. All, or nearly all, the mesenteries bear large 

 gonads. Some of them are mutilated in the type. The color 

 in life was not noted.

 Stimpson, 1854. 



Bunodactis Manni Ver., sp. nov. 



Column more or less cylindrical ; base somewhat expanded. 

 Tentacles numerous, in several crowded series, tapered, acute. 

 Column closely covered with numerous, small, rounded ver- 

 rucae, arranged in many vertical series. 



Color of column usually dark green ; verrucae dark red or 

 brown ; disk, around the mouth pink or light red ; tentacles 

 dark red. 



Height, in expansion 25 to 50 mm (1 to 2 inches) ; diameter of 

 disk 35 mm or more. 



Hawaiian Islands, at and below low water mark in crevices 

 of rocks and attached to stones. 



The above description was prepared many years ago, and 

 I now find no specimens in our collections to correspond with 

 it. It was named in honor of my friend, Mr. Horace Mann, 

 a young botanist who visited the Hawaiian Islands to make 

 botanical and zoological collections and who contributed largely 

 to a knowledge of the botany of the islands, but died before 

 his work was finished.
