Echinola mpas which differs so much from this that it would 
generally be regarded as a different and probably a new species, 
for in some of its characters it is intermediate between the 
eocene Ech. ovumserpentis and the miocene Ech. semiorbis. I 
should be inclined to refer it to the Echinolampas antillarum 
Cotteau (Descr. Echinid. tert. 1875 p. 19, pi. iii., f. 9-11) but 
it has more of a subcircular contour and a conical profile. 
Another Fossil before you is a specimen of Terebratula 
carneoides. This is the finest I have seen of the species. It 
recalls somewhat Ter. bicanaliculata, Schlot. (Bayle and Coquand 
Foss, de Chili, Mem. Soc. Geol. France, 2 ser. t. 4, pi. viii., f. 17- 
19) and also perhaps T. haueri, Karst. (Kreidebildung von 
Sudamerika, taf. vi., f. 1.) The principal distinction between 
T. carnea of the Chalk and T. carneoides of the West Indian 
Eocene is the much larger foramen of the latter. From T. 
depressa, Lam. of the Chalk, T. carneoides is distinguishable by 
the absence of a Deltidium. These characters it may be admitted 
seem scarcely weighty enough to separate species, but they appear 
to be pretty constant. The cretaceous alliances of our Fossil are 
evidently strong, but too much weight must not be attached to 
this point because as pointed out by Davidson the form is 
represented in the living Fauna by T. vitrea. 
T. carneoides was described by me from the Naparima Beds 
in quart. Journ. Geol. Soc. 1866 p. 296 pi. xix. f. 2. It was 
much better figured and described from the Eocene of the Island 
of St. Barts by Thomas Davidson in Geol. Mag. 1874, page 158 
pi. viii., f. 11.
