Trichisina (or Trichechina, as spelled later), with the genera Halicluerus and Trichecus (or Tricheehus, as spelled later). Subfamily 4. Cystophorina, with the genera Cystophora and Morunga. Subfamily 5. Arctocephalina (including all the Eared Seals). In 1866 Gill restricted the family Phocida to the Earless Seals--a group equivalent to Turner's subfamily Phocina--and divided it into three subfamilies, as follows: 1. Phocina, including the genera Phoca, Pagomys, Pagophilus, Erignathus, Halicharus, and Monachus; 2. Cystophorina, including the genera Cystophora and Macrorhinus; 3. Stenorhynchina, with the genera Lobodon, Stenorhynchus, Leptonyx, and Ommatophoca. Gill's Phocina is the equivalent of Gray's Phocina and Trichechina, with the addition to the former of Monachus and the exclusion from the latter of Tricheehus, while Gill's Cystophorina and Stemrhynchina are the exact equivalents of Gray's groups of similar name, except that Monachus is excluded from the latter. In 1869 Gray separated from the Phocida the Walruses and the Otaries as distinct families, thereby restricting the Phocida to the Earless Seals, as Gill had previously done, but divided the Phocida into five "tribes." His classification of the group as presented by him in 1871 is as follows: Family Phocida;. Tribe I. Pliocina, with the genera Callocephalus, Pagomys, Pagophilus Halicyon, Phoca. Tribe II. Halicharina, = genus Halicharm. Tribe III. Monachina,--genus Monaclius. Tribe IV. Stenorhynchina, with the genera Stenorhynclms, Lobodon, Leptonyx, Ommatophoca. Tribe V. Cystophorina, with the genera Morunga and Cystophora. The difference between...
