able fragments of corals. The names of the Foraminifera are as 
follows: 
Amphistegina sp. 
Heterostegina antillea Cushman. Also Antigua and northeastern Mexico. 
Heterosteginoides sp. ef. H. antillea Cushman. Also Anguilla. 
Station 8648. North Shore road, Montpellier (east). 
The rock here exposed is a rather soft, spongy, impure limestone. 
The contained organic remains include determinable Foraminifera 
and indeterminable corals and mollusks. The geologic formation 
seems the same as that exposed at station 8647. The Foraminifera 
‘are as follows: 
Amphistegina sp. Compare above, station 8€47. 
Peneroplis sp. 
~_ Gypsina globulus (Reuss). Also Anguilla; Recent. 
Geologic correlation.—There seems to be no reasonable doubt that 
the same formation is exposed at both Evening Hill and on the North 
Shore road at Montpellier (east). The geologic horizon is either 
middle or upper Oligocene, more probably upper Oligocene. 
Station 6850. Montpellier (east), collected by John T. Quin. 
The specimen referred to by Quin as a volute’ is a species of Orthaulax 
which seems to be the same as a species of Orthaulax I collected at 
Crocus Bay, Anguilla, now identified as O. aguadillensis Maury. The 
specimen from Saint Croix was presented to me for transfer to the 
United States National Museum by the Misses Quin, the daughters 
of the author of ‘‘The building of an island,” and I had a number of 
sections cut of the matrix. Foraminifera are abundant and Doctor 
Cushman furnishes the following list: 
Alveolina sp. Also Saint Martin. 
Orbitolites duplex Carpenter? Also Saint Martin. 
Spiroloculina sp. Also Saint Martin. 
Also indeterminable species of Quinqueloculina, Triloculina, Globigerina, and 
Amphistegina. 
Geologic correlation.—The presence of the species of Orthaulax above 
noted suggests upper Oligocene, about the horizon of the Anguilla 
formation, as the age of the bed from which the specimen came. 
Doctor Cushman says that the Foraminifera are precisely the same 
as those I collected in the yellowish limestone of Saint Martin. The 
horizon may be very low Miocene instead of topmost Oligocene.
