368 J. K. Durrp—En—Jamaican Actiniaria : Part I.—Zoanthee. 
I identify the abundant Jamaican material with Duchassaing and Michelotti’s 
species, mainly from the number of tentacles which these authors give, viz., thirty 
to thirty-two; these coming nearest to those indicated above. The figure which 
they give is of a dried specimen with all the polyps withdrawn to their full 
extent. 
At first I considered it to be Aleyonium ocellatum, Ell. and Sol., obtained 
along with A. mammillosum by Sloane from Jamaica, there being nothing in the 
original descriptions and figures which is not met with in the specimens I have 
examined. M*Murrich has, however (1889, p. 120), appropriated this name for 
some small colonies from Shelley Bay, Bermudas. He does this upon very slender 
grounds, this being the name given it by the collector. He has very kindly 
compared the Jamaican examples with those from the Bermudas, and states 
that they are quite different, especially in their anatomical characters, although 
acknowledging that it would seem as if they were the true P. ocellata, Under 
the circumstances, however, it seems best that M*Murrich’s identification should 
stand, and to allocate Duchassaing and Michelotti’s name, with which the material 
very closely agrees. Andres (1883, p. 323) is evidently acting contrary to these 
two authors in considering the Hughea caraibeorum of Duchassaing as a synonym 
of this species, as, in the “Mémoire” (p. 315), they place it in the genus 
Paractis. 
In a quantity of colonies, it can easily be separated from P. mammillosa, not 
only by the average number of capitular ridges and tentacles, but by the differences 
in size of the polyps, those of the present species being smaller and more closely 
ageregated than the former. Usually the colonies are flatter, and cover larger 
areas. The polyps generally retract to a greater degree, so that the upper 
surface of the colony becomes more uniform. 
Sub-family.— MacrocnEeMIna&, 
Epizoanthus, Gray, 1867. 
Macroenemic Zoanthex, with a single mesogloeal sphincter muscle. The body- 
wall is incrusted. The ectoderm is usually continuous, but may be discontinuous ; 
cell-islets in the mesoglea. Dicecious. Polyps connected by ccenenchyme, which 
may be band-like, incrusting, or greatly reduced, as in the free form. 
The genus Lpizoanthus is defined as above by Haddon and Shackleton (1891, 
p. 632) accompanied by a full account of its history. They recognize twelve
