446 On the “ Prodrome of a Monograph of the Pinnipedes.”’ 
same manner Mr. Gill says F. Cuvier quoted Phoca ursina as the 
type of the genus Arctocephalus, and therefore that generic 
name must be retained for the true Phoca ursina—overlooking 
the fact that the skull figured and described by F. Cuvier as the 
type of his genus is not that of the Phoca ursina of Behring’s 
Straits, to which Mr. Gill wishes to attach it, the fact being that 
until lately almost all the sea-bears or Arctocephali were called 
P. ursina. This allows Mr. Gill to give the name of Ewmetopias 
to the Arctocephali of F. Cuvier, and Arctocephalus to the genus 
which I defined as Callorhinus. 
In the ‘ Proceedings of the Zoological Society,’ when de- 
scribing the skulls of the sea-bears in the British Museum, I 
divided a genus into sections according to the form of the palate. 
Mr. Gill has applied to two of these sections the generic names 
of Zalophus and Halarctus. 
There is one observation of importance in the paper: Mr. Gill 
observes, “ the Halichewrus antarcticus of Peale, very erroneously 
identified with Lobodon carcinophaga by Dr. J. E. Gray, is a typi- 
cal species of Phoca.”’ But he might have stated that Cassin, in 
his text to the plates of the Peale Expedition, refers it to Lobodon 
carcinophaga (see p. 25), and that I stated the figure of the skull 
was “not good” for Lobodon, that Peale says it inhabited the 
Antarctic Sea, and that the teeth in the figure of the skull given 
by Peale and repeated by Cassin are very unlike those of a typical 
Phoca,and somewhat like those of Lobodon. On re-reading Peale’s 
description, I think that it is very probably a new genus, more 
allied to Phoca than to Lobodon; for he says it has six cutting- 
teeth in the upper jaw, and that the four posterior molar teeth 
in both jaws are double-rooted, their crowns many-lobed, the 
cutting-teeth short, simple, and curved; the whiskers flattened, 
waved on the edges. To the animal so characterized the generic 
name of Haliphilus may be applied. 
Though Mr. Peale distinctly says this Seal inhabits the An- 
tarctic Sea, Mr. Gill observes, it “appears to be identical with a 
species occurring along the Californian and Oregonian coasts ; 
consequently there must be some error as to its assigned habitat 
in the Antarctic Sea. I am happy to add that Mr. Peale him- 
self now doubts the correctness of the label on the faith of which 
he gave its habitat; and as a change of name is desirable, I 
would propose that of P. Peale.” Mr. Peale does not describe 
the colour of his Seal. Probably the Seal with which Mr. Gill 
compares it is the Hair Seal, figured in Hutching (‘Scenes of 
Wonder and Curiosity in California,’ p. 180) as the ‘ Hair Seal, 
Phoca jubata”’(!), from the Tarallone Islands, the Halieyon? Cali- 
fornica of my Catalogue of Seals and Whales in the British 
Museum, p. 367.
