1922] Kellogg: Pinnipeds from Miocene and Pleistocene Deposits 61 



When we come to examine the Pleistocene records we find that the 

 remains of Otariidae are still a rarity. In California, Bowers 74 has 

 reported Eumctopias stelleri (= jubata) from deposits of the Pleisto- 

 cene period. The skull, teeth, and vertebrae, as well as other parts 

 of the skeleton, were found associated with Mastodon shephardi, 

 Holomeniscus calif or nicus, Equus occidentcdis, and Escrichtius david- 

 soivi in the grading of the streets of Ventura, California. Ameghino 75 

 is the authority for the statement that the remains of Otaria jubata 

 were frequently found in the postpampean marine formations 

 (" Alrededores de la Plata, Punta de Lara, Quilmes, etc.") of 

 Argentina. 



Dr. Haast 78 conducted extensive explorations in the Moa-bone 

 Point cave, situated on Middle Island, in Bank's Peninsula of New 

 Zealand. In the lower series of layers in the outer chamber of the 

 cave, he found remains of pinnipeds which he designated as Steno- 

 rynchus leptonyx (— Ilydrurga leptonyx) , Arctocephalus lob a I 'us(l) 

 and A. cinereus (=Za.lophus lobatus), and Gypsophoca subtropicalis 

 (= Arctocephalus forsteri Lesson). Practically the same species of 

 vertebrates, as well as objects of human workmanship, were found in 

 the lower series of layers as in the upper series (which he assigns to 

 the Recent period ) with the exception of certain species of Moas. The 

 presence of human remains indicate that these lower layers are also 

 Recent. Peron 77 is credited with reporting the occurrence of fossil 

 remains of Otaria forsteri (= Ar 'otocephalus forsteri) in beds of 

 Pleistocene age in New Zealand, but True 78 as well as myself found 

 on referring to the work cited that there was no mention of this occur- 

 rence on the page given. 



The Miocene genus Allodesmus was a pinniped of large size, closely 

 related in general features to the living sea lions, but possessing char- 

 acters common to Prorosmarus as well as others present in no other 

 pinniped. A comparison of Eumctopias jubata and other Otariidae 

 with this Temblor form indicates that the occipital region has been 

 somewhat modified in recent forms, but that the underlying plan has 

 remained the same. During the course of time the occipital crest has
