This species, united by Tryon with 2\ reticulata, is evi- 

 dently distinct. The fine longitudinal co.'^ta^ and microscopic 

 spiral stri:o at once distinguish it from that form. Apparently 

 a rare shell, and known to me only by the description and 

 figure.

The type of this species ia in the British Museum, and a 

 careful examination of it proves that it belongs to tlie genus 

 Morniida in the Fyramidellidae. 



The torm of the aperture, the character of the sculpture, 

 and the thickening of the labrum (the previous labra forming 

 varices at irregular intervals up the spire) are all features 

 characteristic ot Mormula. 



Mr. J. R. Le B. 'i'omliii has shown me several specimens 

 in his collection from Japan and Lifu, which confirm the 

 distinctness of this species from Mormula rissoina of 

 A. Adams*, also from Japan, to which it bears some 

 resemblance. 



1 might here jxiint out that Ii'issoina rex, of Pilsbry f, 

 is identical with Mormnla lissoimt. Evidently his 8j)eci- 

 mens had not retained their heterostrophe protoeonch, and 

 consequently he way nii>l«-d as rt-Ljards tlh-ir true generic 

 location.
