8 PROCEEDINGS OF THE ACADEMY OF [Jan., 



Length 6.9, diam. 2.3 mm. 



Hirado, Hizen. Types No. 86,128, A. N. S. P., from No. 1,4166 

 of Mr. Hirase's collection. 



Distinct by its turrite shape, convex whorls and spout-like anal sinus, 

 and the beautiful minute sculpture, hardly visible without a compound 

 microscope. 



Drillia albiguttata n. sp, PI. Ill, fig. 19. 



This species, of which only more or less beach-worn specimens have 

 been received, is extremely similar to D. zebra Lam. of the West Indies. 

 It is somewhat more slender. The ground color is chocolate. The 

 sculpture consists of thick longitudinal ribs, 12 on the last whorl, each 

 with a white spot at the shoulder, another below the middle of the last 

 whorl, and there is a white band around the siphonal fascicle. There 

 is a seam-like welt below the suture, and the unworn intervals between 

 the ribs are sculptured with alternately large and small spiral cords. 

 Whether these pass over the ribs or not cannot be ascertained from 

 the examples examined. The lip and anal sinus are like those parts 

 in D. zebra. 



Length 11, diam. 4.5 mm. 



Seto, Kii. Types No. 86,122, A. N. S. P., from No. 1,349 of Mr. 

 Hirase's collection. 



Daphnella radula n. sp. PI. II, figs. 17, 17a. 



Shell fusiform, rather solid, pale brown, indistinctly mottled with 

 white and marked with short brown lines on the larger spiral cords, 

 a series of alternately white and brown squarish spots below the 

 suture. Surface sharply sculptured with alternate spiral cords and 

 threads, about 52 in all on the last whorl, intersected by fine raised 

 longitudinal threads, prominent where they cross the spirals. The 

 lower edge of the anal fascicle is defined by a sulcus slightly unlike the 

 other intervals, where the growth-lines bend abruptly backward. 

 Whorls 8, the first two brown, with the usual diagonally intersecting 

 grooves of Daphnella, the next whorl with three spirals. Last whorl 

 long, tapering above and below. Aperture more than half the shell's 

 length. Outer lip thick but beveled to an edge, obliquely and 

 deeply excised above, a little sinuated near the base. The anterior 

 channel is short and rather shallow. 



Length 13.5, diam. 5 mm.; length of aperture 7.7 mm. 



Hirado, Hizen. Types No. 85,965, A. N. S. P., from No. 903a of 

 Mr. Hirase's collection. 



The shell of this species is thick, like that of Daphnella maculosa
