This species belongs to the group of E. succincta, differing from 

 that form in the more globose and conic shell, rather acute spire, 

 and straightened basal lip. It is named in honor of Mr. H. E.

 Michigan. 



ZONITID^. 

 Lamprocystis spadix S and B., var. cinctus n. v. 



Shell white, with a supraperipheral red-brown band. Formosa

Vitrinoconus Moellendorffi n. sp. 



Shell high-conic, thin, light broAvn ; rather strongly but irregu- 

 larly striate, the strire slightly arcuate, weaker beneath and dis- 

 appearing on the early whorls; outlines of the spire almost straight, 

 the apex obtuse. Whorls 9, very slowly increasing, very slightly 

 convex, the sutures filled by a seam-like cord ; last whorl acutely 

 keeled, the keel compressed, projecting; base slightly convex. 

 Umbilicus contained 34 times in the total diametea* of the shell,
