Echinolampas 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 intern-.ediate between the 
eocene Ech. ovumserpciitis and the iniocene Ech. semiorbis. I 
should be inclined to refer it to the Echinolavipas antillarum 
Cotteau (Descr. Hchinid. tert. 1875 p. 19, pi. iii., f. 9-1 1) but 
it has more of a subcircular contour and a conical profile. 
Another Fossil before 3'oii is a specimen of Terebratula 
carneoides. This is the finest I have seen of the species. It 
recalls somewhat Ter. Schlot. (Bayleand Coquand 
Foss. deChili, 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. t.) 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 ab.sence of a Deltidium. These characters it ma}' be admitted 
.seem scarcely weighty enough to separate species, but the}’ ap- 
])ear to be pretty constant. The cretaceous alliances of our Fos- 
•sil are evidently strong, but too much weight must not be at- 
tached 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 David.son in Geol. Mag. 1874, page 158 
pi. viii., f. 1 1. 
PAPER No. 14. 
NOTES ON THE PASSAGE BETWEEN THE FORA- 
MINIEERA BEDS AND THE RAD/OLA R/AN 
MARLS OF NAPARIMA. 
Read before the Victoria Institute, May 31, 1897 and pub- 
li.shed in the “Proceedings” for that year, pp. 170- 172. 
On a visit I paid some time ago (November, 1894) to the 
vSouth Naparima District, my friend Mr. Ludovic de Verteuil 
jwinted out to me what he believed to be the junction beds 
between the Radiolarian marls and the Foraminifera beds. On 
examination I was able to verify the fact. I was also able to
