THE NAUTILUS. 129 



sculptured with growth-wrinkles and in places faint spiral striae. 

 Aperture slightly oblique, ovate, purplish-black within, the peristome 

 white or flesh-colored, reflexed ; parietal callus transparent; colu- 

 mella not perceptibly folded, oblique above, brown within. Length 

 26.5, diam. 11, length of aperture 10.3 mm.; 25.5, 11, 11 mm. 

 Loo Choo Is. (Mr. Y. Hirase, No. 597). This is by all odds the 

 handsomest Japanese Buliminus, being remarkably rich in co'or for 

 the genus. 



Buliminus luchuanus n. sp. Shell dextral, rimate, oblong-fusiform, 

 rather thin, dark brown, copiously streaked with ragged cream- 

 white stripes ; obliquely wrinkle-striate and very minutely striated 

 spirally. Outlines of the spire a little convex, apex obtuse, whorls 

 8^, moderately convex. Aperture ovate, slightly oblique, orange- 

 brown within, the peristome white, reflexed ; columella oblique, the 

 margin dilated; parietal callus transparent and thin. Length 21, 

 diam. 7.5, length of aperture 8 mm. Loo Choo Is. (Mr. Y. Hirase, 

 No. 598). Streaked like the sinistral Chinese B. Fultoni S. & B., or 

 like B. fasciolahis Oliv., of Rhodes. 



Eulota (JEgistd) Martensiana n. sp. Somewhat similar to E. 

 Friedeliana, but more elevated, the whorls larger in calibre, more 

 slowly increasing, color darker, and sculpture stronger and more 

 dense. Spire low-conic, whorls almost 7, convex, the last slightly 

 carinate, shortly descending in front ; sculpture rasp-like, consisting 

 of densely crowded, short, erect scales, which are not shaggy. 

 Umbilicus open, its width contained 3^ times in that of the shell. 

 Aperture oblique, subcircular, one-fourth excised by the parietal 

 margin, lip narrowly reflexed, white. Alt. 1(H, diam. 17^ mm. 

 Sedake, Osumi, Kiusiu Id. (Mr. Y. Hirase). Named in honor 

 of Pi'of. E. von Martens, of Berlin, whose wide-spread labors in- 

 clude several valuable papers upon the mollusks of Japan. 



Eulota (Plectutropis) inornata n. sp. Shell umbilicate, the diam. 

 of umbilicus contained about 6 times in that of the shell, low conoid 

 with convex base, thin, somewhat translucent, pale corneous, sculp- 

 tured with slight growth-wrinkles and fine, close spiral strire. 

 Whorls 5§, somewhat convex, the last with an acute, submarginate, 

 smooth, peripheral carina ; hardly descending in front. Aperture 

 oblique, angular, the peristome thin, very narrowly expanded and 

 subreflexed below, dilated at the columella!- insertion. Alt. G.3, 

 diam. 12.5 mm*. Loo Choo Is. (Mr. Y. Hirase).
