Tuesday August 2-1910 Port-au-Prince. First day warm and windy. Collected in the morning in zone 8 along the northern medium side of Port-au-Prince harbor. First of two large Pil occurs the only specimen of that seen presenting the entire shell. Also saw four specimens of the large annulated sponge or common in zone 11. Have now about all the fruits it is possible to get in zone 8. The fauna is a small one and very hard to get. In the afternoon collected in zone 10 in the bay leading into Bar-a-melle Cove at the Port-au-Prince post office, this the same place as yesterday's collection. Bactriopods are the chief fossils of this zone. Got a few small Eurytomites. Saw one large Stromatocranium probably 18 inches across, but a smaller specimen. These occur only near the top. The conchili near the base. Zone 9 is a distinctly more granular, heavy ledged, lighter colored dolomite than the limestones of zones 10 and 11. Further it does not check up into grain under the weather as do the last mentioned zones. By persistent collecting one could get together some 10 to 15 species and possibly from once but all are saw are those of the upper zone. The specimens are smaller and the free is pseudomorphous celestite. The dolomite is mottled and is not knotty. Zone 10 above is decidedly more fossiliferous a light blue-grey color and is not dolomite but a limestone that may be somewhat magnesian. Then for it is knotty. Nearly all the low spiny gastropods lie with their feet.
