published papers, generally without any change in the language, and 

 often embracing important typographical errors. In the Appendix, 

 however, some interesting notes are added in respect to the manner in 

 which the eared seals walk, and their attitudes when in a state of re- 

 pose, he having had the opportunity of observing a living sea lion in 

 the Cremorne Garden. 



Nearly coincident with the appearance of Gray's Catalogue of Seals 

 and Whales was the publication of a " Prodrome of a Monograph of 

 the Pinnipeds," by Dr. Theodore Gill,* of Washington. Tins im- 

 portant paper presents to a great extent a new classification of the Pin- 

 nipeds, and introduces numerous changes of nomenclature. The wal- 

 rus, the eared seals, and the earless seals, for the first time for many 

 years,! are again regarded as forming distinct families, as by Brookes, 

 to which are applied respectively the names Rosmaridce, Otariadce, 

 and Phocidce.% The name Otaria, of Peron, is restricted to the South- 

 ern sea lion (Phoca jubata Schreber) ; Eumetopais is proposed as a 

 generic name for the Northern sea lion (Leo marinus Steller, = Otaria 

 califurniana Lesson, — Arctocephalus monteriensis Gray); Zalophus is 

 proposed as a generic name for the Otaria Gillespii McBain, and 

 Halarclus for a group for which the Arctocephalus Delalandii is named 

 as the type ; Arctocephalus F. Cuvier is substituted for the generic 

 name of Callorhinus, proposed by Gray for the Phoca ursina Linne. 

 Brief diagnoses of these genera are given, and a species is indicated as 

 the type of each. A list of the North American species is also added. 



While most of the changes introduced by Dr. Gill in his Prodrome 

 are judicious ones, errors occur in respect to the names of the genera 

 of the Otariadce. These were speedily pointed out by Dr.Gray§ in a 

 short critique upon Dr. Gill's paper, in which Dr. Gray calls attention 

 to the fact that the type of Arctocephalus F. Cuvier was not. as Gill 

 assumed, Steller's sea bear, as is clearly shown by Cuvier's figure of 

 the ?kull of his type of Arctocephalus. Hence Gray properly reinstated 

 his name Callorhinus for the generic name of Steller's Ursus marinus. 

 He does not state, however, to what F. Cuvier's figure refers, this,
