NOTES ON THE GEOLOGY OF THE ISLAND OF ANTIGUA. 

 BY AMOS P. BROWN, PH.D. 



During parts of July and August, 1913, I made a vi^it to the 

 island of Antigua in the hope of finding a place where the Oligocene 

 fauna of the rocks of the island would be in a condition to per- 

 mit of extensive collection. I was in hopes that the fossils would 

 be found in incoherent or soft material as I found them at Panama 

 and as Gabb found them in Santo Domingo. With this in view, I 

 made a rather close examination of practically all places from which 

 fossils had been obtained that were known to the local naturalists 

 of the island. Three weeks were spent on the island and many 

 locaUties were visited. In this search I was aided by Mr. W. R. 

 Forrest, a resident of St. John's, and by Mr. H. A. Tempany, Super- 

 intendent of Agriculture of the Leeward Islands, also of St. John's. 

 To both of these gentlemen I was indebted for many courtesies, and 

 each of them acted as my guide to localities on several occasions. 

 I was not successful in finding any place where the fossiliferous 

 deposits were in a condition permitting of the ready extraction of 

 the specimens, although from what I was able to observe the fauna 

 represented is a large one. 



The island of Antigua lies in latitude 17° to 17° 10' north and 

 between longitude 61° 40' and 61° 55' west of Greenwich. It lies in 

 the outer row of calcareous islands in the Leeward group, which 

 comprises eastern Guadaloupe (Grande Terre), Marie Galante, 

 Antigua, Barbuda, St. Bartholomew, St. Martins, Anguilla and 

 Sombrero. It measures about 9| miles from north to south and 

 12 miles from east to west, with a coast-line of some 70 miles and an 

 area of 108 square miles. The*hape of the island is roughly trape- 

 zoidal or nearly triangular, the coast-line is deeply indented by bays 

 on the northeast and east sides, with Willoughby Bay at the southeast 

 corner, English and Falmouth Harbors on the south coast, and 

 Morris Bay, Five Islands Harbor and St. John's Harbor on the west 

 side. Numerous smaller bays and roadsteads have received names 

 and are used by the coasting boats calling at points along the south 

 and west shores. The surface of the island is roughly divided into
