Thecocyathus recurvatus Poumr. spec. nov. 
Corallum conical, pedicellate, free when full grown, curved at base, covered 
by a thin, pellicular, wrinkled epitheca, extending to the border of the calicle ; 
the coste can be distinguished through it. Septa very slightly exsert, rounded, 
granulated, somewhat plicated near the edge ; in six equal systems, having the 
fourth cycle developed in only a part of them. Pali thick, conical, in front of 
the septa of the first, second, and third order, wanting, however, in front of those 
of the third in the balf-systems lacking the fourth order. Columella composed 
of about ten papilla, very similar to the pali, and on the same level with them. 
Height, 8 mm. ; diameter of calicle, 6 mm. 
(Sigsbee.) Off Havana, 175 fms. 
Conotrochus typus Src. 
A. young specimen from 292 fathoms off Havana was at first doubtfully re- 
ferred to this species, but afterwards an adult one was found among the corals 
dredged by Dr. Stimpson in the Gulf of Mexico. (Depth and exact locality not 
recorded.) There is no striking difference from the European fossil, which is 
well figured by Seguenza and by Reuss. The columella is somewhat more 
loose and composed of fewer papilleo. The larger specimen has the systems, 
which are regular in the young, somewhat incompletely developed, as is the 
case in the fossil. Younger. 12 mm. long ; diameter of calicle, 3 mm. Larger, 
24 mm. long ; diameter of calicle, 10 mm. 
Station No. 16. Off Havana. 292 fms. 
Ceratotrochus hispidus 1۳01187۰ spec. nov. 
Plate I. Figs. 19, 20. 
Corallum attached by a slender peduncle, rather elongated turbinate ; costo 
ornamented with short and thick hirsute spines ; calicle circular ; three com- 
plete cycles, six regular systems. Septa not exsert, rounded, granulated with 
inner border re-entering below. Columella formed of about 10 papillæ, not 
very dense. Height, 1 cm.; diameter of calicle, 5 mm. One single specimen 
was obtained, and this is, as far as I am aware, the first representative of this 
genus found living. 
Station No. 19. Lat. 28° 3/ N., Long. 83° 10 W. 310 fms.
