Phyllactidz with the column provided with longitudinal rows 
of verrucz in its upper part. The foliose marginal tentacles 
(fronds) not arranged in radial series of different degrees of 
development. No sphincter muscle. 
It seems probable that Verrill’s genus Lophactis (68) should 
be included here, leaving only three genera in the family, viz., 
Phyllactis, Oulactis and Asteractis. 
11. Oulactis flosculifera (Les.), Duch. and Mich. (PI. IL, 
Fig. 2; Pl. IV., Figs. 12-14). 
Synon. — Actinia flosculifera — Lesueur, 1817. 
Oulactis flosculifera — Duchassaing and Michelotti, 1860. 
Oulactis conchilega — Duchassaing and Michelotti, 1860. 
Oulactis foliosa — Andres, 1883. 
Andres (83) considered the identification of this form by 
Duchassaing and Michelotti with Lesueur’s Actinza floscultfera 
to be erroneous, imagining the form described by the last-named 
author to be more probably an Evactzs. It seems, however, that 
Lesueur’s description, though not as clear as is desirable, agrees 
fairly well with this form, his marginal ‘“ rows of tubercles sur- 
rounded with small warts’’ being a poor description of the 
external fronds. The term O. conchilega is the name given in 
the index to the plate of Duchassaing and Michelotti’s paper to 
Fig. 7 of Plate VII., which in the text is referred to as O. flos- 
culifera. 
I obtained a single specimen only of this form, buried in sand 
up to the tentacles on the shore of the island of New Providence. 
It has been found also at Green Turtle Cay, Abaco Island, and 
Lesueur’s specimens were obtained at St. Thomas, where it is 
found not only in sand, but also in the crevices of the rocks. 
In my specimen (Pl. II., Fig. 2) the column was of a delicate 
orange-yellow below, shading off above into cream-white, the 
verrucze of the upper part being pure white, and the insertions 
of the mesenteries showing through as white lines. The fronds 
were brown and the tentacles clear translucent white, with 
some opaque white spots, elongated transversely on their inner 
surfaces. Uhtoff’s drawings of the specimens seen at Green 
Turtle Cay represent a somewhat different coloration. They 
are much lighter, the column being translucent white with only 
a very faint yellowish tinge, the insertions of the mesenteries
