116 FOSSIL ECHINI OF THE WEST INDIES. 



from which collections of fossils were made, but stratigraphic data 

 are lacking in most instances. Two species, Clypeaster lanceolatus 

 and C. platygaster, were collected by Dr. Barnum Brown "not far from 

 the University buildings"; C. concavus is also found in Havana. 

 The beds from which these specimens come are at either the Antiguan 

 or Anguillan horizon, with the probability rather in favor of the latter. 

 Clypeaster parvus, reported from Havana by Cotteau, is recorded by 

 Lambert from Antigua, where he says it is mixed with Clypeaster 

 lanceolatus and Echinolampas lycopersicus. 



Calabazar: Encope ci<z from this locality is said by de Cortazar to 

 come from upper Miocene deposits. The species probably belongs 

 stratigraphically above the Anguillan horizon. 



Bellamar: This locality is probably Pleistocene, but it might be 

 Pliocene. 



Matanzas: In the vicinity of Matanzas are deposits of Pleistocene, 

 Miocene, Oligocene, and Eocene age. Clypeaster lanceolatus, C. 

 cotteaui, and Paraster parkinsoni indicate an Oligocene horizon, either 

 Antiguan or Anguillan, or both. Clypeaster cubensis and Laganum 

 elongatum may be Miocene, but new collections with reference to 

 the stratigraphic relations are needed to determine this. 



San Martin: This locality seems to be definitely Anguillan Oligocene. 



Ingenios San Lino and San Marcos: These two localities are Oligo- 

 cene, but what horizon they represent is not determinable from the 

 two species of echinoids, Clypeaster concavus and C. planipetalus , 

 found at them. 



Cienfuegos: Near this place are strata ranging in age from Cretaceous 

 to Miocene. Without data on stratigraphic relations precise correla- 

 tion is not possible, but the occurrence near Cienfuegos of Clypeaster 

 concavus and Brissopsis jimenoi show that Oligocene strata, probably 

 the Anguillan horizon, are present there. Echinopedina cubensis, 

 doubtfully referred by Cotteau to the Eocene at Cienfuegos, may be 

 a Miocene species, as Doctor Jackson has identified it in collections 

 from the Gurabo formation, Dominican Republic. 



Santa Clara Province, no definite locality: Clypeaster concavus is 

 known from both the Antiguan and the Anguillan Oligocene. 



Santiago de Cuba: Specimens of three species collected by Lieut. 

 Fred P. Black, U. S. N., are not accompanied by stratigraphic data. 

 Of these species, Cidaris tribuloides (Lamarck), Echinometra prisca, 

 and Echinoneus cyclostomus Leske occur at the Anguillan horizon. 

 Cidaris tribuloides and Echinoneus cyclostomus are still living in the 

 West Indies. Although these species may come from the Miocene 

 La Cruz marl, their stratigraphic relations are doubtful, because 

 more ancient deposits are present in the vicinity of Santiago. Echino- 

 lampas lycopersicus was obtained by de la Torre near Santiago in 

 beds of Oligocene age.
