Baker, F. C— The Digitations of the Mantle in Physa. Bull. Chicago Ac. Sci., 

 1901, vol. ii, pp. 225 — 228, pis. i, ii. 



The author has examined the edge of the mantle which is reflected over the 

 parietal wall, in various species of Fltijsd, and finds the marginal digitations very 

 uniform in those species whose shell exhibits little or no variation, while in those 

 species subject to great variation, there is a corresponding variation in the mantle.

 Choo Islands. Proc. Malac. Soc. Lond., 1901, vol. iv, p^^. 191 — 201, pis. 

 xix — xxi. 



The main value of the report lies in the generic corrections and the figures, 

 unfortunately these latter are not printed in the text but on a glazed paper. Two 

 new varieties are described, viz. Trishojilita gooclivini v. carinata, and Eulota 

 (Aegista) friedeliana v. tumida.

Smith, J. P. — The Larval Coil of Baculitcs. Amer. Nat., 1901, vol. xxxv, pp. 

 39—49, p!s. A, B. 

 Until comparatively recently Baculitcs was supposed to be an ammonite that had 

 reverted to the orthoceran form, but the discovery, in the Cretaceous beds of 

 Dakota, of young examples possessing a larval coil attached to the straight shaft, 

 was rightly interpreted as indicating the descent of this genus from a coiled ancestor. 

 A recent find of numerous larval coils of B. chicocnsis, has enabled the author to 

 describe the ontogeny and phylogeny of the genus, and to illustrate the same. 



Smith, J. Perrin and Weller, S.—Prodromitcs, a new Ammonite genus from 

 the Lower Carboniferous. Journ. of GeoL, 1901, vol. ix, pp. 255 — 266, pis. 

 vi — viii. 



In this new genus we have, the authors state, the oldest known and most complex 

 ammonite yet described from strata older than the Permian. The new genus is 

 founded partly on Miller's Goniatites gorhyi, of which corrected figures are given, 

 and a new species P. 2>rnematurus. 



Fischer, H- — Description d'une espece nouvelle de Melampus provenant du Golfe 

 de Gascogne. Journ. de Conchyl., 1900, vol. xlviii, pp. 66 — 69, figs. 1,2. 



Dr. Fischer now describes the specimen of Melampus previously referred to as 

 M. exiguus, Lowe (J. de Conchyl., 1899, p. 55, fig. 1), and proposes for it the name 

 of M. hiscaycnsis.
