ZEUGLODON. 377 



cetaceous order has been restored from fossil remains dis- 

 covered in formations of the miocene age in Europe and [North 

 America. The teeth of this carnivorous whale, for which the 

 generic name Zeuglodon seems now to be generally accepted, 

 were first described and figured by the mediaeval palaeontolo- 

 gist Scilla, in his treatise entitled Be Coiyoribus Marinis 

 (4to, 1747, tab. xii., fig. 1), and have since given rise to 

 various interpretations. The originals were obtained from 

 the miocene strata at Malta, and are now preserved in the 

 Woodwardian museum at Cambridge. 



The remains of a gigantic species of the same genus, 

 discovered in miocene formations of Arkansas, Mississippi, 

 were described and figured by Harlan as those of a rep- 

 tile, under the name of Basilosaurus* Teeth of a smaller 

 species, discovered by M. 

 Grateloup, in miocene 

 beds of the Gironde and 

 Herault, were ascribed 

 by him also to a reptile, 

 under the name of Squa- 

 lodon.-\ In 1839 Dr. 

 Harlan brought over his 

 specimens of Basilosau- 

 rics to London, and sub- 

 mitted them to the 

 writer's inspection, by

whom they were determined to be mammalian and cetaceous. 

 The entire skeleton has since been obtained from miocene 

 deposits in Alabama, revealing a length of body of about 70 

 feet. The skull is very long and narrow ; the nostril single, 

 with an upward aspect, above and near the orbits. The jaws 

 are armed with teeth of two kinds, set wide apart ; the
