numerous unequal spiral striae between them, all slightly crenulated 

 by the close, fine growth-striae. The high and rather slender spire 

 is composed of 6 very convex whorls, the apical ones being broken off 

 in the type specimen. The suture is deeply constricting. The last 

 whorl is convex, rapidly contracting below, and produced in a long, 

 slender and nearly straight anterior canal. Aperture ovate, hardly 

 longer than the narrow canal at the base. The outer lip is thin, and 

 retracted in a broad shallow posterior sinus. Length 36.5, diam. 12.5 

 mm. ; length of aperture with anterior canal 20 mm. 



Japan, exact locality unknown. Type No. 70,941, A. N. S. P. 



This peculiar Fusoid species has been in the collection of the Acad- 

 emy for a good many years, during which time I have not seen any- 

 thing much like it. It may possibly belong to the Pleurotomidw. 



BUCCINID^E. 



Tritonidea tosana n. sp. PI. IV, fig. 33. 



Shell wide-fusiform, solid ; brown, closely marked with many narrow 

 black bands. Sculpture of numerous small longitudinal folds, which 

 are nearly obsolete on the last whorl, disappear on its last third, and 

 elsewhere do not pass below the periphery. There are about 15 rather 

 acute, black primary spiral cords on the last whorl, the intervals 

 between them densely striated with similar but smaller spirals of two 

 or three sizes. Whorls nearly 7, slightly convex, the last inflated in 

 the middle, contracted below. The convex, moderately prominent 

 siphonal fasciole is sculptured like the rest of the shell. Aperture 

 blue-white and indistinctly sulcate within, the throat smooth; pos- 

 teriorly it is acute and slightly channelled, there being a small callous 

 pad on the inner lip. Outer lip sulcate within, bevelled to an acute 

 edge, which is tessellated with black and yellowish. Columella concave 

 above, oblique and straight below, the white columellar callous showing 

 several inconspicuous transverse plicae near the edge. 



Length 22.5, diam. 12 mm. ; aperture 14 mm. long. 



Kashiwajima, Tosa. Types No. 85,990, A. N. S. P., from No. 1,462 

 of Mr. Hirase's collection. 



This species is most nearly related to T. undulata Schepman, but 

 differs from that in the much smaller and more numerous longitudinal 

 folds. 



Cyllene japonica n. sp. PI. IV, fig. 34. 



Shell fusiform; flesh-tinted, indistinctly marbled and mottled with 

 white and irregularly speckled with brown; vertically rather weakly 

 striate and spirally grooved, the grooves narrow, separated by flat in-
