flesh-color, specked with olive and flake white. Yellowish brown 
specimens also occur. 
The tentacles can be contracted in length, but are not retractile, 
so that it can be easily preserved partially expanded. The raised 
annuli of the tentacles are usually distinct in alcoholic specimens. 
In some small specimens, preserved in formalin (var. monilifera), 
the thickened bands are longer than thick, thus becoming truly 
bead-like, and separated only by narrow constrictions. Possibly 
this may be a distinct species. 
Many specimens of this species do not have the tentacles and 
mesenteries arranged in regular hexamerous cycles. Octamerous 
specimens have been described by MeMurrich from the Bahamas. 
Hermaphrodite specimens have been observed by Duerden (1902).* 
Gonads are borne on mesenteries of the 2d and 3d cycles and some- 
times'on those of the Ist cycle, except the directives. There is no 
distinctly defined sphincter muscle, though the general musculature 
may appear a little stronger at a certain level than elsewhere, per- 
haps due to a stronger local contraction. 
Var. solifera (Lesueur). 
Actinia solifera Les., op. cit., p. 173, 1817. 
The large specimen figured on our plate xxxi, fig. 2, belongs to 
this form, described by Lesueur, but his specimens were much 
smaller. Its distinctive character is the presence of interrupted flake- 
white spirals, usually not distinctly thickened in life, on the tentacles. 
Intermediate states between the spirals and the raised rings fre- 
quently occur, and hence the two forms have been united. 
This species and the varieties are also common in the West Indies.

This is one of the most common species, but does mot grow nearly 
so large as the last. It occurs in the crevices and under rocks and 
* Dr. J. E. Duerden has given a very full account of the anatomy and histol- 
ogy of this species in Actinians of Porto Rico, pp. 855-358. His specimens, 
however, were not full grown, though sexually mature.
