TECHNICAL HISTORY SPECIES. 455 



As the author himself now freely admits, iu the light of the 

 material he has since had opportunity of examining, Phoca rich- 

 ardsi and Phoca pcalel are both synonyms of Phoca mtulina. 



Gray, later in the same year, in a short paper* devoted to 

 a notice of Gill's " Prodrome," proposed to refer Peale's Hali- 

 chcerus antarcticus to a new genus which he named Halipliilus. 



Gray in 1871, in his " Supplement to the Catalogue of Seals 

 and Whales in the British Museum" (pp. 2-5), raised the num- 

 ber (nineteen) recognized by him in 1SG6 to twenty-two, omit- 

 ting two and adding five, mainly by .separating the species of 

 the North Pacific from their allies of the North Atlantic. The 

 species added are: 1. u Halicyon % pealei" (exGi]l, = HaUcho3rus 

 autarcticKs, Peale); 2. "Pagophilus ! equestris" (ex Pallas, cov- 

 ering f<iNci<if<(, " Shaw," and anneUata, Eadde) ; 3. "Pagophilml 

 ochotensis" (ex Pallas); 4. Phoca " naurica" (nautica and albi- 

 gena, Pallas); 5. Mohingaangustirostris (Macrorhinus angustiros- 

 tris, Gill). Of these, two only (" equestris" and angustirostris) are 

 valid. He .also tabulated the species according to their dis- 

 tribution, as follows: 



"North Atlantic. 



"CaLLocephaliis vitulimis. 

 "Callocephalus dimidiatus. 

 "Pagomys foetidus. 

 "Pagophilus gro?nlandicus. 

 "Phoca barbata. 

 'Halichcerus grypus. 



' ' North Pacific. 



"Halicyou richardsi. 

 "Halicyon pealei. 

 "Pagophilus ? equestris. 

 "Pagophilus ? ochotensis. 

 ''Phoca uaurica. 

 " Morunga anc-ustirostris." 



"Cystophora cristata." 



"Halicyon californica" is thus omitted, and is nowhere men- 

 tioned in the " Supplement," and the same is the case also with 

 "Pagomys ? largha". Whether the former was accidentally 

 overlooked, or intentionally retracted, does not appear. From 

 Dr. Gray's "Hand-List of Seals, Morses, Sea-Lions, and Sea- 

 Bears in the British Museum," published in 1874, in which " it 

 is proposed to give an account of all the specimens" of these 

 animals in the British Museum, it appears that the only speci- 

 mens of North Pacific Phocids there represented were the three 

 referred to Halicyon richardsi. Five out of six of his North 

 Pacific species were apparently unknown to him except through 

 authors' descriptions, and are, as I hope later to satisfactorily 

 show, merely nominal. The Phoca annellata of Eadde, referred 

 by him to his "PagopMlwl equestris", relates not at all to this
