Aff. S. Eendei, S. ct B., sed minus solidula, minor; margo superior 

 peristomatis ad suturam minus recedens ; lamella superior in parte 

 parietis non margine dextro conjuncta ; peristoma minus incrassatum ; 

 anfr. penultimus in umbilicum recedens. Diam. maj. 6, min. 4, alt. 

 3 mm. 



I. Sircptaxis paulus, n.sp. Mouth, x 3.

Sab. — Unkno-n-n. Chinese region probably. 



Two specimens of tliis shell, without indication of habitat, were 

 acquired by me in a miscellaneous collection at Stevens' sale-rooms. 

 I Upon recently ref;eiving a specimen of 8. Uetidei, its resemblance 

 to my unnamed shells struck me at once ; and I submitted them to 

 Dr. Boettger, who wrote : " New species, next to S. Heiidei.^'' It 

 differs from that shell in the deeper umbilicus ; the penultimate 

 whorl recedes further ; the upper lamella on the parietal wall is not 

 joined to the right margin of the peristome, and the latter is less 

 reflexed at the suture ; it is also smaller and less solid.
