No. 1.] ACTINIARIA OF THE BAHAMAS. 7 
genus from the family Sagartidz to which it properly belongs, 
and, making the inability to retract the tentacles of too great 
importance, placed it with the Antheadz. 
Duchassaing and Michelotti (66), apparently overlooking 
Gosse’s Azptasia, established a new genus Bartholomea, whose 
definition differs from the original description of Azptasza only 
in that the position of the cinclides towards the equator of 
the column is particularly mentioned, the genus being thus 
separated from Adamsza on the one hand, and WMemactis on the 
other. Milne-Edwards’ genus Dysactzs is also retained by these 
authors, the form referred to it being probably an Azpfasia 
whose cinclides were not very distinct.

My reasons for uniting the two genera described by Lesueur 
(17) will be more suitably discussed after the form which I 
studied has been described. 
My specimens were found attached to the lower surface of 
the blocks of coral rock, or in cavities in these, along the shore 
of New Providence. Among the forms figured by Mr. Uhtoff 
I notice one which is evidently A. aznulata, and Lesueur’s 
specimen was obtained in the hollows formed in the madrepore 
rocks upon the shores of the island of Barbadoes. The form 
known as A. solifera was found by Lesueur and Duchassaing 
and Michelotti at Guadaloupe and St. Thomas, according to 
Lesueur, in old shells, particularly those of Zurbo versicolor (?). 
This species consequently ranges from the Little Bahama Bank 
as far south, at any rate, as Barbadoes. 
The coloration of all my forms was constant (PI. I. Fig. 1). 
The column is for the most part pure white, shading off above 
into a pale brown, being in this darker region flecked with 
opaque white. The cinclidal tubercles are usually more trans- 
parent than the surrounding surface, and therefore are quite 
evident. The disc is brown, with white triangular spots at the
