Flem., and A. reticulatus Phil., the ducussation not being so fine as 

 in the former, nor so coarse as in the latter. (Ad., 1. c., p. 348.) 



Rifunsiri, Japan, 35 fms. 



ANATOMUS MIRIFICUS A. Adams. Shell ovate, depressed ; spire 

 plane ; broadly and profoundly umbilicated ; whorls 2|, rather plane, 

 regularly and elegantly clathrate with elevated radiating and con- 

 centric lines ; umbilical region nearly smooth ; aperture very ob- 

 lique ; inner lip receding. 



In this large and beautiful species the entire surface of the whorls 

 is regularly and delicately, finely clathrate, and the umbilicus is very 

 wide and open. (Ad., 1. c., p. 348.) t 



Lo-shan-Kow, Shantung. 



ANATOMUS STAMINEUS A. Adams. 



Shell ovate, depressed ; spire plane ; umbilicus moderate ; whorls 

 2?, nearly plane, broadly clathrate with thread-like elevated radiat- 

 ing lines, stronger below the carina, and concentric elevated striae ; 

 umbilical region with elevated concentric lines ; aperture rounded- 

 ovate ; inner lip receding. 



This species is widely clathrate, with conspicuous thread-like 

 radiating and concentric lines, the former of which assume on the 

 spire a lamellar character ; the umbilicus is moderate.

Shell globose, very thin, subdtaphanous, concentrically very del- 

 icately striate, narrowly umbilicate ; whorls 3, carinate ; spire small, 

 scalate ; slit not very deep, occupying the carina of the whorl ; lip
