PALEOBOTANY AND EVOLUTIONARY HISTORY

706. Barett, A. Contribution to the study of the "Siphoneae verticillatae" of the Calcare 

 di Villanova-Mondovi. [The verticillate Siphoneae of the Villanova-Mondovi limestone.] Atti 

 Soc. Etal. Sci. Nat. eMus. civ. St. Nat. Milano 58:216-230. 1919— The "Calcare di Mondovi" 

 typically exposed — as the name indicates — in the region of Mondovi 'Piedmont) and in par- 

 ticular in the massif of Villanova a few kilometers from the town, is rich in diminutive triassic 

 algae, which, about 1865, Prof. Bruno recognized for the first time there. Different specimens 

 of like fossils were studied by Gumbel and by Zittel who referred them to the Muschelkalk 

 and the Wettersteinkalk horizons. For this work Barett examined some specimens of the 

 Calcare di Villanova at the Museo Geologico di Torina, sent by Prof. Bruno, and especially 

 the abundant material of his own collecting not only from Villanova, but also from other locali- 

 ties of the surrounding calcareous zone: M. Calvario, Gravagna, P.loline and Torre, Pever- 

 agno. Material of different appearance according to the source or origin, but always crystal- 

 line, so that the fossils, although superficially seemingly well preserved are profoundly 

 metamorphosed in the interior, rendering their preparation and study most difficult. Barett 

 recognized the presence of the following Diploporidi in the Calcare di Mondovi: Kanlia debilis 

 Gumbel, K. philosophi Pia, K. dolomitica Pia, Tentlosporclla gigantea Pia, T. hercules Sapp., 

 T. vicctina Tornquist, and in addition the following, which he proposes as new: Kantia 

 philosophi var. gracilis n. var., K. monregalensis sp. n., and K. (?) Brunnoi sp. n. He describes 

 and figures them all. — Despite the great number of specimens examined, their different orifiin< 

 or sources, and the extraordinary abundance of the individuals contained in them, this study, 

 because of the above-mentioned difficulty, has not yielded as great results as might have 

 been hoped; nevertheless from this it stands proved that in the Calcare di Mondovi there 

 are also encountered the Kanlia philosophi and dolomitica typical of the Muschalkalk, and 

 the Teutlosporella gigantea and T. vicentina, hitherto not noted; and there results then the 

 confirmation that the horizon is to be referred to the lower Neotriassic— R. Pampanini.

 carpon). Ann. Botany 34: 135-137. 1920.— Evidence is given to show that specimens 

 described by Bassler as proving the existence of a sporangiophoric lepidophyte and referred 

 to a new genus Cantheliophorus, as well as similar specimens previously described by Nath- 

 orst, are really examples of Sigillarian microsporophylls. — '.'-'. P. Thompson.

 dclphus, but very likely belongs to P. palaeophilus Ckll. (1908).— .7. C. Nelson.
