TROCHOSERIS, Epwarps AND Haimn. 
Trochoseris catadupensis, sp. nov. | 
Plate XXXIX. Figs. 5, 6. 
Corallum short cornute, attached by a pedicel, calice flaring out. Height of 
corallum 13 mm. Diameters 3 mm. below calicular margin: longer, 12 mm. ; 
shorter, 10 mm.  Diameters of calice : greater 16 mm.; lesser 15.5 mm. The 
outer surface marked by low subacute costeo, alternately larger and smaller in | 
size, with granulated or dentate margins. The wall, where it could be cleaned, 
showed no perforations. The exact number of septa could not be made out 
with absolute certainty; by counting coste and septa where not broken off, 
140 seemed to be the number, — i. e. there are five complete cycles with 
about half the members of the sixth. To be sure, the septa are much 
crowded together. The members of the first, second, and some of the third 
cycles reach the columella ; those of the higher anastomose to the lower after 
the type of junetion in Trochoseris distorta (Michelin). The septa are solid, 
their sides are granulate, and their margins appear to be dentate. Synapticul® 
present in the interseptal loculi. The interseptal loculi filled up with caleareous 
deposit. The calicular fossette in the axial region is narrow and moderately 
deep. The columella is small, rather deep seated. It appears to be composed 
of several trabecule. The characters of the columella could not be made out 
as fully as was desired, but one is present, though it is small. 
Locality. Catadupa (R. T. Hill, collector).

Remarks. The specimen on which this species is based is apparently well 
preserved, but on account of the calcareous filling of the lower portion and 
the indurated condition of the matrix, caleareous sand and clay, many hours 
| of study were necessary before the features embodied in the above description 
|] could be discovered. The description is not so full as is desirable, but in | 
every essential feature the species coincides generically with Trochoseris, as a 
very careful comparison with T. distorta showed, and as it is peculiar for the 
West Indies, it should be easy to recognize it hereafter.

Plate XL. Figs. 1-4. 
Form of corallam: only one piece, with a few attached very young indi- 
viduals, has been submitted to me. This piece is 27 mm. long; on the lower 
end the greater diameter is 14 mm., the lesser 12.5 ; on the upper end the 
cross section is practically circular, and is about 17 mm. in diameter. The
