4 THE NAUTILUS. 



flexed in front. Umbilicus more broadly open. Alt. 7, diam. 16 

 mm., umbilicus o mm. wide. 



Sodayama, Tosa. Types no. 84783, A. N. S. P., from no. 1022 

 of Mr. Hirase's collection. 



E. s. var. hadaka (Nautilus xvii, 105) is a much less depressed 

 form, measuring, alt. 9.5, diam. 16, umbilicus 4 mm. wide, and alt. 

 8, diam. 14 mm. 



Eulota {AegisUi) eminens n. sp. 



Sbell broadly and deeply umbilicate, low-trochiform, dull yellow- 

 ish-biown, finely striate, the last strite on the last whorl broken into 

 low granules, which when quite unworn bear short cuticular laminse 

 in places. Spire convex-conic. Whorls 6| to 7, slightly convex, 

 closely coiled, and very slowly widening, the last whorl obtusely 

 subangular at the periphery, and descending a little in front, very 

 convex beneath. Aperture very oblique, rounded, about one-fourth 

 of the circle excised at the parietal wall. Peristome thin, narrowly 

 expanded, reflexed below. Alt. 7.3, diam. 10.8, width of umbilicus 

 3 mm. 



Toba, Shima. Type no. 86493 A. N. S. P., from no. 590a of 

 Mr. Hirase's collection. 



This species belongs to the group of Aegista mivnda, but differs 

 from all the known species by its elevated spire, higher than in any 

 other Japanese Aegista, and approaching the contour of the species 

 referred to the section Codorus. 



Eidota (Aegista) mimula var. goniosoma n. var. 



This race resembles mt'nmla, trachyderma and mikuriyensis in the 

 rather small aperture with thin, expanded lip, subreflexed below, but 

 not thickened within. The spire is low conoid-convex, the periphei-y 

 strongly angidar and the base convex, abruptly curving into the wide 

 umbilicus. The lusterless surface is brownish-yellow, freckled with 

 buff dots, finely, rather irregularly striate, and in some specimens re- 

 taining short, triangular cuticular laminae below the periphery. 

 Whorls 5^ to 5|. Alt. 6.5, diam. 11.3 to 12 mm., width of umbili- 

 cus 4 mm. 



Amagisan, Izu. Types no. 86462 A. N. S. P., from no. 1165 of 

 Mr. Hirase's collection. 



On account of its strongly angular periphery, this might be con-
