402 T. Davidson — Tertiary Brachiopoda. 



a well known Liassic species. It may likewise perhaps be referable 

 to one of the species from the same locality described by Schaf hault 

 in his work on the Kressenberg (1863), such as perhaps to his 

 T. picta, but if so, that designation had been previously assigned to 

 a recent species, and consequently could not be retained for the shell 

 under description. It is also, I think, the same species as the one, 

 perhaps incorrectly, identified by Ooster in his work on the " Bra- 

 chiopodes fossiles des Alpes Suisses" (pi. ix. 1863), under the 

 designation of Terehratula Kichxii, Galeotti ; but Dr. L. de Koninck, 

 to whom I sent drawings of our Italian species, assures me that it is 

 specifically distinct from the one described by Galeotti in his memoir 

 " Sur la constitution Geognostique du Brabant," pi. 4, fig. 15, 1837, 

 which was subsequently better figured by Nyst in his work " Sur 

 les coquiiles et Polypiers de Belgique," pi. 29, fig. 4. When adult , 

 T. Kichxii and its synonyms T. trilohata and T. Icevis are elongated 

 shells, wide near the beaks, and tapering considerably towards the 

 front ; T. Kickxii occurs in the sands of Assche and Gand, and also in 

 the Eocene sands of Cassel, near Dunkirk. The interior of our Italian 

 fossil is not known. Sig. Meneghini procured his specimens from 

 the volcanic tufifa, or Lower Eocene of St. Giovanni Ilarione, in the 

 Vicentin territory ^ and he gave to it the manuscript designation of 

 T. Illarionis, but as Mr. Bayan has spelt the name with an M, in his 

 published memoir, it will be preferable to leave it so in this com- 

 munication. The shell was found by Mr Bayan in his Eocene stages 

 B. and C., along with Nerita Schmiedeli at the Val di Ciampo, Croce 

 Grande, Pozza; also at La Gichelina, near Malo, etc. This rock, 

 which in some places assumes the form of a friable green sand, would 

 correspond to the horizon of the Calcaire grassier of the Paris basin 

 (lower part), for it contains such shells as Terebellum sojpitum, Strombus 

 Barlonensis, and other such species of that epoch.

Sicilian Lower Pliocene, specimens of this shell were described by 

 Sig. Sequenza under the designation of W. peloritana, but it was sub- 

 sequently recognized by Mr. Jeffreys, Sig. Sequenza, and myself to be 

 referable to the still existing Wald. septigera of Loven. Mr. Jeffreys 

 is still, however, impressed with the idea that both W. septigera 

 and W. peloritana should be considered synonyms of Philippi's 



' For the better understanding of the various Eocene localities referred to in this 

 paper, it may be mentioned that a great alluvial depression extends between Vicenza 

 and Scliio. It is in the hill to the west of this depression that are situated Castel- 

 vecchio, Bolca, Chiampo, Malo, St. Giovanni Ilarione, Val di Lonte, Gambugliano, 

 Castelgoraberto, and St. Urbano. In the hills to the east, in the direction of Bassano, 

 we find Lugo, Laverda, Crosara ; and still further to the east the Valle Organa and 

 Castelcies, which are beyond Brenta, near Possagno ; on the contrary Mossano, 

 Lonigo, and Brendola are in the chain of hills known by the name of Colli Berici, 

 which extend to the south of Vicenza, and between that town and the Monti 

 Euganei.
