130 THE NAUTILUS. 



BuKminus andersoniamis var. echigoensis P. & H., n. var. 



Shell similar to B. andersonianus Mlldff. except that the spire is 

 a little wider, not (|uite so straightly conic, and the size is much 

 greater. Dark vinous-brown with a green-bufF border below the 

 suture, the mouth purple-bordered inside. 



Length 29| to 30^, diam. 11 to 11^ mm.; whorls fully 8. 



Myokozan, Echigo. Types no. 83896 A. N. S. P., from no. 750a 

 of Mr. Hirase's collection. 



B. andersonianus was originally described from Yesso ; but Mr. 

 Hirase has found it not only in Ojima, the southern province of that 

 island, but also in the province Uzen, in Nippon (Hondo); the speci- 

 mens being typical. This large race is from still farther south. 



HELICINA JAPONICA AND RELATED FORMS. 



BY H. A. PILSIiKY. 



Helicina japonic a ■wi\& described from " Tabu-Sima," that is, Tobi- 

 shima, an islet of the Pix)vince Ugo, on the west coast of Nippon. 

 Adams gave no dimensions; but the figures in Sovverby's Thesaurus 

 Conchyliorum., which were evidently drawn from liis specimens, 

 measure alt. 8, diam. 9.6 mm. However, even where no size-mark 

 is given in the Thesaurus, the figures of many small species are 

 slightly enlarged. Thus, on the same plate with H. japonica, the 

 figures of H. convexa, concinna, etc., are enlarged, while those 

 of some other species are not so. Therefore the dimensions of these 

 figures cannot be relied upon as showing the true size of H. japonica. 

 The specimens before me from Tobishima, the type locality, measure 

 alt, 6, diam. 8 mm., or are a little smaller, alt. 5, diam. 7.2 mm. The 

 surface is glossy or dulled by slight erosion, and is rather finely but 

 deeply striate. The lip is expanded and in fully adult shells is dupli- 

 cate, and very much thickened on the face. The moderately thick 

 basal callus is densely, conspicuously roughened. The specimens 

 from Sddo are like those of Tobishima, but of a dull red-brown color. 

 A larger race, diam. 9.5 to 10.5 mm., red, or sulphur-yellow, glossy 

 and handsome, occurs at Kashima, Harima. It has the fine sculpture 

 of typical japonica. 



H. reinii Kobelt, described as a variety of H. japonica, is mucli 

 larger, alt. 10, diam. 14 mm. The type locality is unknown, but
