THE NAUTILUS. 87 



NEW SPECIES OF BUCCINUM FKOM THE KURIL ISLANDS. 



BY II. A. PILSBRY. 



Buccinum inclitum n. sp. 



Shell ovate-pyramidal, solid, cream-colored with a few incon- 

 spicuous reildish-brovvn stains. Tlie spire is straightly j)yramiUil, 

 the apex small, the first whorl wanting in the type specimen. 8 

 whorls remain; they are very convex and separated by deep, chan- 

 nelled sutures. Below the suture the flattened, sloping surface is 

 sculptured with four or five spiral cords. These are followed by 

 three very strong spiral ribs, separated by deep striate intervals. 

 On the last whorl there are four large ribs, grouped near the 

 periphery, which is formed by the second rib ; below them the base 

 has about & gradually decreasing spiral cords, with one to three 

 smaller cords and threads in each interval, exclusive of those on the 

 convex, si phonal fascicle. Over the whole of this sculpture there is 

 a very fine spiral striation, and the upper slope of the whorls has 

 small radial waves, making the ribs slightly nodose. The aperture 

 is tinted with pale yellow on both lips, the outer lip being somewhat 

 expanded, and posteriorly flaring. The anterior canal is short and 

 wide. 



Length 82, diam. 46 mm. 



Etoro, Chishima [Kuril Is.]. Type is no. 88768 A. N. S. P., 

 from no. 1704 of Mr. Hirase's collection. 



This noble and beautiful species is somewhat related to B. leuco- 

 stoma and B. martensianum, but it is much more strongly sculptured 

 than either. B. carinatnm Dkr. is also related, but it differs by the 

 small number of spiral keels. 



Buccinum chishimanum n. sp. 



Shell ovate, rather thin but moderately solid, yellowish olive- 

 green, the principal spiral ribs typically red-brown with light spots. 

 Spire slate-blue or ashy-purple. Whorls 6, the apex slightly 

 mamillar and smooth, the last whorl ventricose, sculptured with 

 numerous very unequal .spiral cords and threads, the larger cords 

 widely spaced on the upper half, more numerous below. Over all 

 there is a microscopic sculpture of distinct, fine and close fold-like 

 growth-stria^, and very fine, subobsolete spiral strife. The suture is 

 bordered with weak folds, sometimes stronger and tubercular. The
