are also met with at Port Antonio. All these possess the thickenings on the 
tentacles, and the dise tubercles are strongly developed. 
It is evidently a common West Indian anemone, having been recorded from the 
following localities: attached to stones on the sand-banks of the island of Barbados 
(Lesueur); St. Thomas and Barbados (Duchassaing and Michelotti) ; usually 
fastened to blocks of coral rock in shallow water, Bahamas (M*Murrich). 
Professor M°’Murrich has already described the form in considerable detail. 
The salient features in which the Jamaican examples differ are the variability in 
colour, and the entire absence, in some instances, of the thickenings on the tentacles. 
The first mentioned character is especially noticeable in young specimens, these 
being largely a mottled grey and black, in strong contrast with the more brilliant 
colours of the largeexamples. PP. mucosus, from the Australian seas, also displays 
somewhat similar colour variations. 
The presence or absence of the thickenings on the tentacles would be worthy 
of at least specific distinction were it not that every gradation can be traced 
between the two extremes. 
In respect to the tubercles on the tentacles the West Indian representative of 
the genus should be compared with the several species known from the Indo- 
Pacific region. The former never shows anything beyond simple or bilobed 
thickenings on the oro-lateral aspect of its tentacles, while the tentacles on 
P. loligo, Khr., from the Red Sea, may bear pedunculate and branched outgrowths ; 
P. mucosus, H. & S., and P. levis, Kwiet., also carry slightly dendritic appendages.

Stichodactyline, in which the tentacles are of two forms, marginal tentacles of 
the ordinary form, arranged in a single cycle; inner tentacles lobed or tuberculi- 
form and irregularly arranged. 
Under this family Professor M*Murrich includes the two West Indian species, 
Actinotryx (Rhodactis) Saneti-Thome and Ricordea florida. Owing to more recent 
researches, it seems to me imperative to remove Ricordea from this association and 
to assign it a place among the Discosomide, a position already hinted at both by 
MM. Duchassaing and Michelotti (1866, p. 122), and by Professor Verrill (1869, 
p. 462). 
The form and arrangement of the tentacles must undoubtedly be the determin- 
ing consideration in the classification of the order; and in the two species men- 
tioned, these bear no close relation one to the other. Ricordea agrees with the 
chief characteristic of the Discosomide in possessing tentacles all of one form and
