THE NAUTILUS. 21 



NOTES ON A FEW SHELLS. 



BY C. F. ANCET. 



Prof. H. A. I'ilsbry has described and figured a few jears ago 

 (Proc. Acad. Nat. Sciences, Phila., 1901, p. 682, pi. xxxvi, fig. 

 30—41) a Japanese Clausilia which he called CI. oscariana, in honor 

 of Dr. Oscar Boettger, the well-known German writer on Clausiliae. 

 He was probably unaware that a Chinese species of this genus re- 

 ceived the same' name from P. V. Gredler (Zur Conchylien-Fauna 

 von China, xvii Stiick, Wien, 1892, p. 8), who, curiously enough, 

 has dedicated his species to Dr. O. von MoUendorfF whose Christian 

 name is Otto not Oscar. At all events, the name Oscariana cannot 

 stand for the Japanese Clausilia, this homonym having several years 

 of priority. Hence, I propose to substitute for it the name Clausilia 

 pilsbryana Anc. 



I must also call attention to Claus. oscari Thiesse (Bttg., Proc. 

 Zodl. Soc. 1883, p. 34, fig. 16) a somewhat distinct form of CI. 

 schuchi, V. Voith, perhaps entitled to specific rank, though Dr. West- 

 erlund (Fauna der in der Palaarktischen region lebenden Binnen- 

 Gonchylien, iv, p. 140) calls this a variety of CI. schuchi. 



Terebra histrio Desh., was described (Journ. de Conch. 1857, pi. 

 iv, fig. 11) without a locality, from a specimen in Deshayes' collection. 

 1 have procured a fine specimen collected on the coast of Senegal to- 

 gether with T. hitorquata Desh., already known as West African, 

 Drillia rosacea Reeve, Marginella petiti Duval, M. goodalli Sow., M. 

 cleryi, Petit. My example, consisting of 16 whorls, is 42 mill, long 

 and 10 mill. wide. For the identification I am indebted to Mr. Ph. 

 Dautzenbero;. 



Natica prietoi Hidalgo (Journ. Conch, xxi, p. 332, Moll. Esp., pi. 

 20B, figs. 2-3), a very rare shell, discovered on the coast of Southern 

 Spain, was found again by myself at Algiers. I secured a large, 

 somewhat worn example and a smaller one very perfect. With this 

 I detected a specimen of anotlier scarce species worthy of record, viz., 

 Scalaria candidissiina, Monterosato.
