cise line between the two classes, which pass into each other through some of 

 their lowest-organised forms. (Fries, Th. M.) The Lichenes of the Ukrain, 

 with a plate— p. 13-20. Sixty-four species are enumerated, of these new Biatora 

 polychroa, which however Massalongo is inclined to identify with Lichen corneus 

 R. B. A new name Trachylia lucida is proposed for the Acolium viriduium 

 Framm., which is quite distinct from Tr. viridula of the same. (Boeck) On 

 the inhalation and exhalation of water by plants — p. 280-303. Geology.

(Steenstrup) On the remains found in peat mosses, showing that the Beaver, 

 Castor fiber, the Capercailzie, Tetrao urogallus, the Penguin, Aha impennis, 

 and the Land Tortoise, Emys lutaria, were former natives of Denmark — p. 1-20, 

 381-388. (Same) On a pair of maxillae of a colossal Cephalopod, cast up on the 

 strand of Raaberg in 1853; resembling the genus Ommatostrephes D'Orbigny — 

 p. 199. (Schicedte) Report on the Odonata, Libehulidae, collected in the ex- 

 pedition of the Galatea — p. 108-125. The species enumerated amount to eighty, 

 of which forty-nine are indicated as new. Several tables are given to illustrate 

 the geographical distribution of the family, from the observations made on this 

 expedition ; but the season of the year was in great part so unfavourable for col- 

 lecting, that this, with other circumstances concurring, detracts from the import- 

 ance of the materials thus obtained. (Same) On the g. Broscosoma Rosen- 

 hauer, and its relation to Miscodera — p. 351-358. Concluding for the reunion of 

 the two under one genus, Miscodera. The alleged difference in the fore tarsi of 

 the male, Schicadte did not find substantiated by actual inspection. The choice 

 between the names he has founded not on the intelligible and sure ground of 

 priority, but on a critical reason, which it is clear many entomologists would not 

 assent to. (Same) On the structure of the Thorax in insects, as a ground of 

 classification— p. 358-364. The characters of which LeConte has applied for 

 the classification of the Carabidse would be adverse to the views maintained in 

 the preceding article. Schicedte goes into a criticism of them, and examines 

 more particularly the position of the intermediate coxee in relation to the sternal 

 and pleural divisions of the thorax, which he reduces to four types in the Cole- 

 optera, according as the mesothoracic epimeron and episternon, or one of the 

 two, or neither, forms a portion of the socket of the coxa. Two of these types 

 are exemplified in the Carabidae ; and the further subdivisions of one of the 

 resulting groups are traced out, thus — I. Mesothoracic epimera extending to the 

 coxae. A. Metathoracio epimera without an external appendage, i. Antennce
