110 GEOLOGY AND PALEONTOLOGY OF THE WEST INDIES. 



The greater number of collections from Cuba appear to have come 

 from a single geologic horizon which is exposed at numerous localities 

 in the vicinity of Santiago. The fauna, which is characterized by a 

 profusion of pectens, bears a close resemblance to those of Tampa and 

 Anguilla, but may be a little younger. The fossils from Consolacion 

 del Sur (station 3474), among which is Orthaulax inornatus, have not 

 been found elsewhere in Cuba, but tie up with the Tampa and Anguilla 

 faunas. The small collections from Calabazar (station 4291) and 

 Guajay probably are of nearly the same age. The fossils from Havana 

 (station 4292) may be somewhat younger than the others, but the 

 evidence is inconclusive. 



Interesting collections were obtained by Wiebusch (stations 3652, 

 5312) from the asphalt beds at the Angela Elmira mine near Bejucal. 

 These include both fresh-water and marine species which may have 

 been derived from beds of different ages. The fossils are referred 

 doubtfully to the Oligocene. The list follows : 



FOSSILS FROM THE ASPHALT BEDS NEAR BEJUCAL. 



Levifusus? angelicus, n. sp. Unio bitumen, n. sp. 



Cyprsea semen, n. sp. Margarita naticoides, n. sp. 



Hemisinus bituminifer, n. sp. Solemya sulcifera, n. sp. 



Hemisinus costatus, n. sp. Myrtaea? asphaltica, n. sp. 

 Elmira cornu-arietis, n. gen. et sp. 



DESCRIPTIONS OF SPECIES. 



Scaphander species. 



A well-preserved cast of a species of Scaphander measuring 28 mm. in 

 altitude and 16.4 mm. in diameter was collected by T. H. Wren in Cuba. 

 Locality. Calabazar, Cuba, station 4291. 

 Geologic horizon. Oligocene. 



Conus species. 



(Plate 1, Figures 5 a, 6, 6 a, 6.) 



Casts of the interior of a species of Conus having a high, apparently 

 bulbous nucleus and with deeply channeled sutures were obtained at 

 Crocus Bay, Anguilla. The smaller whorls are rounded on top, but 

 the more mature whorls are angulated at the periphery. 



Another species of Conus occurs in the Miocene of Santiago, Cuba, 

 station 5255, and a third in the upper Eocene of St. Bartholomew, 

 station 6897a. 



Locality. Crocus Bay, Anguilla, stations 6894, 6966, Vaughan. 



Geologic horizon. Oligocene. 



Figured specimens. U. S. Nat. Mus., Nos. 166947, 166948. 



Tunis species. 



From Crocus Bay, Anguilla, there is a fragment of a pleurotomoid 

 shell which resembles Turris albida (Perry) in general appearance. 

 The major sculpture, as in the species cited, consists of three prominent 

 spiral threads; the secondary sculpture of spiral threads is lacking on
