I.— New and little-known Gastropoda from the Upper Cre- 

 taceous of Tennessee. By Bruce Wade. Proc. Acad. Nat.

WE have referred in a previous issue (Geol. Mag., 1917, p. 471) 

 to the notable results of Dr. Bruce Wade's study of the 

 Gastropod fauna from the Upper Cretaceous Ripley formation of 

 Coon Creek, in McNairy County, Tennessee. The fossils from this 

 locality are in a remarkable state of preservation, and consequently 

 afford excellent material as a basis for the establishment of new 

 generic- types. We have now before us a second contribution, in 

 which further new forms are established. Among them is Conorbis 

 mcnairyensis, a new species founded on a single specimen, which is 

 the only member of the Conidse in the fauna. This record is 

 important on account of its being the first typical representative of 

 the genus in the Upper Cretaceous; it shows all the salient features 

 exhibited by Sowerby's Conus dormitor, the type of the genus 

 Conorbis, from the Eocene of Western Europe. 



Three new genera in the Yolutidse are established, and a new 

 species is assigned to Grabau's Falsifusus and to Conrad's Linosoma, 

 also of this family. Hyllus is a genus (type, R. callilateras, n.sp.) of 

 large, unornamented volutes, with expanded bodies and low spires. 

 The characteristics of this genus resemble those of Liopeplum, but 

 there are differences in the form of the spire and the disposition of 

 the columellar plaits. The new genus Boltenella (type, B. excellans, 

 n.sp.) includes a group of well-defined forms of fulguroid shells, 

 with large paucispiral protoconchs and subdued ornamentation, 

 probably intermediate between the Busyconidse and the Fusidse. 

 Scobina is a generic name given to a number of shells similar in 

 general shape to Rercorhynchus . The strongly inflated body 

 resembles Conrad's Rapa cancellata from the Cretaceous of India, 

 but in the new genus there is a marked increase with age in the 

 spiral angle. S. bicarinata, n.sp., is the genotype. The new species 

 assigned to the genus Falsifusus, F. mesozoieus, is a fragile, slender 

 shell, marked by spinose terminations of the axials along the shoulder 

 angle. This form and Kaunhowen's Fusus bicinctus are the first two 

 species from the Upper Cretaceous to be referred to Falsifusus. In 

 another genus, Lirosoma, a new species (cretacea) is again recorded 

 for the first time from the Cretaceous. This form resembles the 

 generic type from the American Miocene. 



The Buccinidse are represented by one new genus, Seminola (type, 

 S. crassa, n.sp.), named after a tribe of Indians who formerly in- 

 habited the south-eastern coastal plain. The genus resembles 

 Meek's Odontobasis, of which the fusiform outline distinguishes it 

 from the globose form of Seminola. 



An elegant little pyriform shell, with a depressed spire, Fcphora 

 proquadricostata, n.sp., has again the interest of being the first 

 representative in the Cretaceous of a genus well known in the Upper 

 Tertiary of the Atlantic Coast district. Belonging to the same
