\ Mr. Gill intends to publisli a ^ Monograph of the Pinni- 
I pedes, ^ and has given a Prodrome of it in Proc. Essex Instit. 
vol. V. pp. 1-13. He proposes a classification in which the 
i divisions and groups are characterized, and the genera tabulated ; 
of species only the type of each genus is mentioned. He adds 
i also a list of North American Seals ; it comprises 13 species, 
i The following is the arrangement proposed : — 
' First family. Phocida2. 
I Subfamily I. Piiocin-® : — 1. Phoca (L.)= Callocephalus (F. Cuv. & Gray) 
I =iHalicyon (Gray). 2. Pagomys (Gray). 3. Pagopliilus (Gray). 4. Eri- 
1 (Gill) = P/ioca (Gray). 5. (Nilss.). (S. 3Ionachus(F\Qm. 
! & Gray) = Heliophoca (Gray) — Phoca monachus. 
j Subfamily II. Cystophorinje (Gray). 
Subfamily III. Stenorhynchin^ ; adopted from Gray’s system after re- 
i moval of Monachus. 
i Second family. Otariidje (Brookes, Gervais). 
1 1. Otaria (P<5ron) — Ph. juhata. 2. Arctocephalus (F. Cuv.) = Callorhinus 
\ (Gray) — Ph. ursina. 3. Eumetopias (Gill) — Otaria calif orniana =Arctoce- 
phalus montcriensis (Gray). 4. Zalophus (Gill) — Otaria gillicspii. 6. Hal- 
\ arctus (Gill) — Arctocephalus delalandii. 
f Third family. Bosmaridje. 
/ Dr. Gray has published critical remarks on this Prodrome 
' of a Monograph,^^ in Ann. & Mag. Nat. Hist. xvii. pp. 444-446. 
I The Halichoerus antarcticus of Peale will probably prove to be 
the type of a distinct genus, for which Dr. Gray proposes the 
j name of Halophilus, 
\ Prof. Peters, having examined the specimens of Otari<R in the 
Berlin Museum, and at a later period also those in the London 
j and Leyden Museums, has published the results of his observa- 
' tions in Monatsber. Ak. Wiss. Berlin, 1866, pp. 261-281, and 
I 665-672. He remarks that, although at present it must appear 
i useful and necessary to divide the species into groups, lie docs 
; not regard them as genera, and that the generic names proposed 
i may be dropped as soon as the species are better known. He 
i arranges them thus (pp. 670-672) : — 
\ a. Otaria (s. s.). Hair short, without imder-fur ; ears very short (15-20 
\ mm. long) ; osseous palate very concave, reaching to, or nearly to, the hamuli 
\j)terygoidei.
