Creek ravine near the base of Church Hill may possibly belong to 

 some squalodont. 



Several fragments of a mandibular ramus with a molar in place 

 as well as a free premolar were collected in the Santa Margarita forma- 

 tion of the Tejon Hills in Kern County, California. These remains 

 are too fragmentary to be of much value in comparative studies. The 

 molar teeth of this phocid from the Santa Margarita were two-rooted, 

 and, as the anterior and posterior portions of these teeth are broken 

 away, it is impossible to allocate its true relationships. 



MIDDLE PLIOCENE (SCALDISIAN) 



A still greater variety is added to the pinniped fauna by the vast 

 Scaldisian estuary of the Antwerp basin, which furnishes a rather 

 large assemblage of genera and species at this stage. Van Beneden 121 

 has distinguished the following forms: Mesotaria ambigua, Paleophoca 

 nystii, Gryphoca swtilis, Platyphoca vulgaris, Phoca vitulinoides, 

 Callophoca obscura, Phocanella pumila, and Phocanella minor. 

 According to Allen, 122 Mesotaria is closely allied to Cystophora, or at 

 least referable to the Cystophorinae. He also came to the conclusion 

 that the relationships of the other genera were to be expressed as 

 follows: Paleophoca with Monachus, Gryphoca with Halichoerus, 

 Platyphoca with Erignathus, Callophoca with Pagophilus, and Phoca- 

 nella with Pusa. Altogether, this assemblage, as listed by Van Bene- 

 den, is the most comprehensive of any deposit known. A list of the 

 localities in the Antwerp basin from which the various pinnipeds 

 described by Van Beneden were obtained was prepared by Mourlon. 123 

 More precise information regarding the occurrence of the pinnipeds 

 in the Antwerp basin, hereinafter mentioned, can be obtained from 

 this paper. 



UPPEE PLIOCENE (ASTIAN) 



A rather unusual find was made when Pristiphoca occitana was 

 described by Gervais and Serres 124 from the marine sands of Mont- 

 pellier in the Department of Herault, France. This left mandibular
