No. 1.] ACTINIARIA OF THE BAHAMAS. I5 
brown, with lighter longitudinal striz marking the lines of in- 
sertion of the mesenteries. The disc and tentacles are brown, 
flecked with opaque white patches. The peristome and stomo- 
dzum are white, or in some cases the peristome is brown, 
slightly paler than the disc, and flecked with white spots. 
The base adheres firmly, and is slightly larger than the col- 
umn, measuring about I.4 cm. in diameter. It is thin enough 
to allow the insertions of the mesenteries to be seen through. 
The column is cylindrical and contractile, measuring about 
1.5 cm. in height and 0.gcm. in diameter. The cinclides are not 
very distinct in the living animal, although in preserved speci- 
mens they stand out as tubercles quite as distinctly as in the 
other variety, being arranged very much in the same manner 
as in it. In one specimen the numbers in the various series, as

Acontia were emitted with comparative readiness, and were 
always white. There is no sphincter muscle, and the endoderm 
contains “yellow cells.” 
The tentacles are very entacmzous, and are arranged in four 
cycles, their formula being 12, 12, 24, 48. The length of those 
of the inner cycle is 1.2 cm., and of those of the outer cycle 
0.75 cm. As in variety a, they are all smooth, cylindrical, and 
pointed, and on account of the absence of a circular muscle are 
not infolded in contraction. 
The description given of the arrangement of the mesenteries 
of variety a applies equally well for this variety, the only differ- 
ence being that the internal edge of the longitudinal muscle 
bands ends more abruptly (Pl. III., Fig. 2). I did not succeed 
in observing the stomata. 
Reproductive organs are present only on the mesenteries of 
the second cycle. In the specimens examined only ova were 
present, and they were not quite mature. 
Young Form.— This was obtained in considerable numbers 
on the grass along the shores of the lake mentioned above, and 
I was at first inclined to consider it a distinct species; but 
further study has led me to place it here as a young form of 
A. tagetes. In coloration it agrees closely with variety £, just 
described, the column being brown with longitudinal striae indi- 
cating the insertion of the mesenteries. Above the color be- 
comes deeper, and in this darker region the column is flecked
