A New Species of Sawshark, Pristiophorus Schroederi, from the Bahamas
Three specimens, 38.3, 64.5, and 80.5 cm in total length, representing the first of the family Pristiophoridae known from the Western Hemisphere were collected from 350 fathoms in the Santaren Channel (the type locality) and from 500-520 fathoms north of Little Bahama Bank, and constitute the type series. In the diagnosis these are compared with the 4 other known species of the genus Pristiophorus and the single known species of the genus Pliotrema. The comparisons are based on examination by the authors of specimens in the collections of the U.S. National Museum, the Museum of Comparative Zoology at Harvard, and the British Museum (Natural History). An elaboration of the first 5 vertebrae common to the family and unique among sharks is reported.
