Mr. Dublancq-Laborde informs me that besides the formations of 

 Mont Pelee there are in Martinique two fossilferous horizons. 



i. Limestones at St. Marie and caravelle containing Litho- 

 thamnion Orbitoides {Lepidocylina) and Spiroclypeus. These are 

 probably eocene. 2. Beds near La Trinite containing Turitela 

 tornata, Natica sulcata clypeaster elipticus and Orbitolites compla?i- 

 ata. These correspond to the West Indian miocene, with which 

 is correlated the miocene of Panama, Jamaica ( Bowden), Haiti, 

 Trinidad (Caroni series) etc., etc. 



These indications support the view of Dr. Watts that a fos- 

 siliferous limestone formation underlies the volcanic series of the 

 Antilles ; and we have evidence here that the volcanic period 

 was subsequent to these formations, and was therefore of miocene 

 date. These calcareous formations were deposited along the 

 margin of the atlantis land, the Caribean Sea being then a gulf 

 communicating with the Pacific Ocean, as shown in the map ap- 

 pended to my paper on the geological connections of the Caribean 

 Region (Trans. Can. Inst., 1908-9.) 



This discovery of Mr. Laborde's does not affect generally my 

 observations on the geology of Antigua but it may involve some 

 correction of the views of Purves on the central plain of that 

 island. The analogy of the Martinique formations would dispose 

 us to regard that central plain as a part of the calcareous forma- 

 tion dislocated and broken-up by volcanic agency and altered b}^ 

 erosion, and subsequent deposits due to marine action, and to the 

 hot springs and fluviatile phenomena developed near and along 

 the line of the great Antillean dislocation passing through An- 

 tigua.

I take the opportunity of bringing to the notice of The Soci- 

 ety the work of Miss Maury on the Paleontology of Trinidad. 

 Miss Maury was a member of Mr. Veatch's party under the aus- 

 pices of the General Asphalt Company of Philadelphia, and she 

 did the Paleontological work. Miss Maury has added a large 

 number of new names to the list of Trinidad fossils, but it will 

 remain for further investigation to determine which of these are
