The outer lip is a good deal damaged in both of the specimens 

 received. 



Conus gratacapii n. sp. PI. I, figs. 10, 10a. 



Shell slender and lengthened, the diameter somewhat exceeding 

 One-third of the length, the high straight-sided spire occupying two- 

 fifths the length of the shell. Apex broken. 12 whorls remaining are 

 flat, with the smooth peripheral angle immediately above the suture, 

 but scarcely projecting, a little more prominent on the upper than on 

 the lower whorls. The surface of each whorl is a trifle concave, and 

 sculptured with about 6 low, unequal spiral cords. Below the periph- 

 eral angle the last whorl is sculptured with about 25 spiral grooves, 

 weaker above, stronger and closer below; and the growth-striae curve 

 strongly backward near the angle. The aperture is very narrow, and 

 of equal width throughout, and two-thirds as long as the shell. 



Length 30, diam. 11 mm.; length of aperture 20 mm. 



Length 31, diam. 11.5 mm.; length of aperture 20.3 mm. 



Kikai, Osumi, in a Pliocene (?) deposit. Types No. 85,947, 

 A. N. S. P., from No. 1,554 of Mr. Hirase's collection. 



This peculiar species resembles C. kikaiensis in sculpture, but is 

 unlike that in form. It is named for Mr. L. P. Gratacap, of the Ameri- 

 can Museum of Natural History. 



PLEUROTOMID^l. 

 Drillia streptonotus n. sp. PI. Ill, figs. 18, 18a, 186. 



Shell slender and t unite, solid, light brown with an obscure band 

 below the suture and another on the base. Sculpture of regular, 

 subvertical rounded folds as wide as their intervals, about 18 in num- 

 ber on the last whorl, where they disappear a short distance below the 

 periphery. These are crossed by numerous spiral threads, alternately 

 larger and smaller, but on the lower, contracted half of the last whorl 

 the spirals are regular and equal. Under a strong lens the whole sur- 

 face is seen to be covered with densely crowded rows of minute 

 papillae. Whorls 9^, strongly convex. The first whorl is smooth and 

 rounded; then an acute peripheral keel begins, and a whorl and a 

 half later low radial sculpture and fine papillae appear. The first two 

 or three sculptured whorls are angular, the keel persisting to the end 

 in the peripheral thread. Aperture flask-shaped, wider above, the 

 outer lip with about 6 small teeth within, arranged in pairs; deeply 

 excised above, and produced in a short recurved spout at the anal sinus; 

 contracted below to form a short siphonal canal. 



Length 8.8, diam. 2.8 mm.; length of aperture 3 mm.
