procured by mj-self from Anguilla I affixed, in 1865, a speci- 
men of a spine identical with C. angiiilla;, Cott. 
Miocene, Anguilla. 
2. Cidaris loveni, Cott. 
Cotteau, Echinides tertiaires de S. Barts and Anguilla, 
p. 10, pi. i., f. II — 14. 
Though very near to C. vielitensis, this species appears 
to be characterized by good and permanent differences. 
3. Echmoinetm prisca, Cotteau. 
Cotteau, Echinides tertiaires, p. 12, pi. i., f. 19—27. 
The specimens are similar in all respects to those 
recorded b)' me (Jour n. Geol. Soc., vol. xxii., p. 299), as 
Ech. acufera, and perhaps differ sufficient!}" from the 
recent form to be under the circumstances entitled to a 
recognition as of specific rank. 
4. Echinoneus minor, Le.ske. 
Cotteau, Echinides tert., p. 14, pi. i., f. 28—30. 
M. Cotteau does not give a specific name to this. It 
is probably the same as theA'cA. cyclostomus of my paper, 
for which, however, the name Ech. minor may be pre- 
ferable. 
5. Clypeaster antillarum , Cotteau. 
Cotteau, Echinides tert., p. 15, pi. ii., f. i — 3. 
In M. Cotteau’s paper this is stated to be from 
Anguilla, but the label assigns the species to Portorico, 
and I am inclined to the belief that the latter is correct. 
6. Clypeaster concavus, Cotteau. 
Cotteau, Echinides tert., p. 16, pi. ii., f. 4 — 8. 
In my account of the Westindian fossil Echinidae I 
considered this to be the Clyp. ellipticiis of Michelin. 
Cotteau disagrees with this view, and gives the name of
