2 FOSSIL ECHINI OF THE WEST INDIES. 



which was a fine series of Echinoderms from the islands of St. Barthol- 

 omew and Anguilla. These were studied by M. Cotteau, who dis- 

 tinguished 33 species, all carefully described and delineated in a paper 

 published in 1875. By the kindness of Professor Cleve, the collection 

 came into the hands of Mr. Guppy, who published brief notes on it. 

 Later, it was purchased with some other material, in 1893, by the 

 United States National Museum, where it now is. 



Dr. William H. Dall, through whose intervention this collection 

 came to the museum, writes that the specimens were glued to wooden 

 tablets. The names, sometimes written and sometimes printed from 

 Guppy's publications, were pasted on the tablets. There was no indi- 

 cation of their locality other than the island, as "Trinidad," and none 

 as to whom they had been given for description. Dr. Dall personally 

 copied the labels when they were removed from the tablets. Some of 

 the material in the Cleve collection is beautifully preserved, while parts 

 of it are in poor condition. 



I regret to say that Cotteau's figures were very freely and often, it 

 seemed, unwarrantably restored in making the drawings from the speci- 

 mens, so that structural details figured may be quite wanting in the 

 specimen. This statement can be verified by comparing the photo- 

 graphic figures with Cotteau's published figures of the very same 

 specimens. The measurements of specimens often differed from those 

 given in Cotteau's paper. I would say that my measurements were 

 made with a steel caliper rule from the specimens in Washington, with 

 Cotteau's memoir open before me, so that any discrepancies in measure- 

 ments are a difference of observation. 



The Cleve collection is the most extensive collection of fossil Echini 

 from the area that I know of. It was studied during two visits to 

 Washington when notes were taken and specimens were selected for 

 photographing, which was done under the supervision of Dr. C. Wythe 

 Cooke of the U. S. Geological Survey, to whom I would express the 

 warmest thanks for the pains he took in this work. 



Quite a large amount of echinoid material was collected by Dr. T. 

 Wayland Vaughan from the islands of Antigua, Anguilla, and St. 

 Bartholomew, and a few Echini from the Dominican Republic. From 

 the American Museum of Natural History, besides several isolated 

 specimens, was borrowed a fine lot of material from Porto Rico, includ- 

 ing some very interesting species. This Porto Rican material was 

 collected by Dr. C. A. Reeds, with the aid of a field assistant, Mr. Pren- 

 tice B. Hill, while on an expedition under the joint auspices of the New 

 York Academy of Sciences, the Porto Rican Government, and the 

 American Museum of Natural History. 



The Philadelphia Academy of Natural Sciences kindly loaned a few 

 specimens from Antigua, Cuba, and Trinidad. A few interesting species 

 from Cuba and Jamaica were studied in the Museum of Comparative
