REMARKS ON SOME NEW SPECIES FROM TRINIDAD 



KATHERINE VAN WINKLE 



The material from which the following species were obtained 

 was collected in 191 2, on the island of Trinidad bj' A. C. Veatch 

 under the auspices of the General Asphalt Companj- of Phila- 

 delphia, Miss Carlotta J. Maury being the Paleontologist. The 

 stratigraphy and paleontology" was subsequently worked up b}* 

 Dr. Maury and published in the Journal of the Acadeni}' of Sci- 

 ences of Philadelphia. A few forms not reported seem interest- 

 ing and worth}' of description. 



Thanks are due to Professor Harris for the use of the mater- 

 ial from both Virginia and Trinidad and for suggestions in the 

 determinations. 



The descriptions of the localities where these forms were 

 collected have been taken from the notes of Miss Maur}-, that 

 were found with the material.
