280 PALAEONTOLOGY. 



Rth'iMEYFE, L. Ueber den Bau von Schale nnd Schadel bei lebenden 

 und fossilen Schildkroten als Beitrag zu einer palaontologischen 

 Geschichte dieser Thiergruppe. [Structure of shell and skull in 

 living and fossil Shield-Reptiles, &c.] Yerh. naturf. Gesell. Basel, 

 6 Theil, Heft 1, pp. 1-137. 

 Contains a short synopsis of genera and species of Chelonia found 

 fossil at Solothurn, and described in the author's previous paper (Me- 

 moirs Swiss nat. sci. Assoc, vol. xxv.), and discusses their affinities to 

 recent shield -reptiles ; notices fossil GTielonidce from other European 

 localities. Ckelone pulchrieeps and C. Benstedi of Owen are said not to 

 be Sea-Turtles at all, but allied to Chelydidfe, and the former to Che- 

 lymys. Platemys BidlocJcii, Ow., is supposed not to differ from Pleuro- 

 sternon. The Eocene Chelonidce described by Owen^ it is suggested, 

 might be formed into a new group, Chelonemydidce, as they have the 

 skulls of Turtles but the shields of Emydidce. E. B. T.

Arrives, amongst others, at the following conclusions : — 1. Du- 

 ring the Chalk period Indian and Pacific types predominated, mixed 

 with a few Atlantic forms, especially in the warmer parts of the 

 ocean. 2. The Mediterranean and Atlantic types gain an importance 

 in Tertiary times. 3. In Tertiary times there was communication be- 

 tween the Indian Ocean and the Mediterranean. 4. There was direct 

 communication between the old and new continents, which seems to have 

 lasted longest in the north. G. A. L.
