FOSSIL ECHINI OF THE WEST INDIES. 



INTRODUCTION. 



At the request of Dr. T. Way land Vaughn, I undertook to make a 

 study of and prepare a report on the fossil Echini of the West Indies, to 

 form a part of his geological and palaeontological survey of that region. 



I would express my deepest obligations to Dr. Hubert Lyman Clark, 

 Curator of Echinoderms in the Museum of Comparative Zoology, 

 Cambridge, whose great knowledge of Recent Echini and whose most 

 generous help were placed constantly at my disposal. 



The species described or otherwise considered include Echini from 

 the Greater Antilles, namely, Cuba, Jamaica, the Dominican Republic 

 in Haiti, and Porto Rico. Also Echini are described or listed from a 

 number of islands of the Lesser Antilles, including Anguilla, St. Bar- 

 tholomew, Antigua, Guadeloupe, and Barbados, also from the island 

 of Trinidad off the coast of South America. Besides the species of 

 which I have had material, the attempt is made to record all species 

 previously published as occurring fossil in the West Indies. I have 

 recognized 89 species; of these, I have had specimens of 57, of which 16 

 are described as new; 32 of the recognized species were not seen, but 

 in order to give completeness they are included, with a reference and 

 locality but without description; they are largely from Cotteau's 

 Spanish report on the fossil Echini of Cuba. 1 



The material on which this report is based is from several sources, but 

 principally from the Cleve collection of Echini, now the property of 

 the U. S. National Museum, from the islands of St. Bartholomew and 

 Anguilla. This collection is very important on account of its extent and 

 also as being the basis of Gustave Honore Cotteau's beautiful memoir, 

 "Description des Echinides Tertiaires des Ties St. Barthelemy et An- 

 guilla," published in 1875. Of the 33 species described in that memoir, 

 the Cleve collection is represented in every species, and in 23 of the 

 species the Cleve collection alone is recorded. What other material 

 Cotteau had, as stated in his memoir, was from the museums of Stock- 

 holm and Upsala, or from his own collection. 



The late R. J. Lechmere Guppy, of Trinidad, wrote of this collection 

 (1882, Scientific Assoc. Trinidad Proc., part 12, pp. 193-199) that in 

 1868-69 Professor P. T. Cleve, of the University of Upsala, traveled in 

 the West Indies and investigated the geology and mineralogy, an 

 account of which he published (1871, Kongl. Sven. Vet. Akad. Handl., 

 vol. 9, No. 12). Professor Cleve made a collection of fossils, among

 Michelin, Desor, and Gregory, referred to in foot-notes, pages 6, 9, and 10.
