of Phoca ambigua, and who has discussed its relationships in a brief 

 footnote as follows : 



Dans le meme Musee (i.e., Musee d'Histoire Naturelle de Hambourg) se trouve 

 aussi urie premolaire du Squalodon ambiguus, Mstr., provenant de l'Oligocene de 

 Biinde. Je desire faire observer que cet Odontocete Be peut pas etre incorpore 

 dans le genre Squalodon meme. J'ai en 1 'occasion de voir, bien que rapidement, 

 les originaux de Minister, au Musee de Munich, sous la conduit du Dr. Max 

 Schlosser. C'est un Squalodontide primitif, — ce qu 'indique deja son age Oligo- 

 cene, — qui doit faire partie du groupe caracterise par Neosqualodon, Dal Piaz, et 

 Microsqualodon, Ab., et cet Odontocete prouve que les Squalodontidae ne peuvent 

 pas deseendre de Protocetus, Eocetus ou Zeuglodon, mais qu 'ils doivent etre rattaehes 

 aux Creodontes par d'autres formes. On doit, peut-etre, eonsiderer comme un tel 

 ' ' missing link ' ' le Miorozeuglodon caucasicus, Lyd. 



LOWER MIOCENE ( BUEDIGALI AN ) 

 Workmen have recently uncovered in the diatomaceous shales at 

 Lompoc, California, the impression of an entire phocid limb. This 

 specimen is the earliest known member of the Phocidae. Fossils dis- 

 covered in this horizon are usually very fragile though the impressions 

 left after the removal of the disintegrating bones are so perfect that 

 excellent easts can be made. This specimen will be discussed more 

 fully in a later paper. 



MIDDLE MIOCENE (HELVETIAN) 

 Among other bones sent by Ed. Lartet from the Sansan to Blain- 

 ville was a fragment of a mandible containing a large canine tooth 

 in situ and two other trilobate and palmated molariform teeth. Blain- 

 ville 0i thought that this fragment exhibited points of relationship with 

 the phocids and perhaps a few with the hunting tiger of India. It is 

 more probable that this fragment belongs to a Pseuelaelurus or some 

 related genus. 



Several of the teeth that the Reverend Probst had in his collections 

 at Unteressendorf, Germany, were thought by Van Beneden 95 to be 

 closely related to his form Paleophoca nystii. These teeth were found 

 in the celebrated sandstone quarries at Baltringen, in Wurttemberg. 



UPPER MIOCENE (TORTONIAN) 

 Although a considerable number of species of phocine pinnipeds 

 have been described from various deposits in Europe, none are so
