wider than those from other localities, and the lunella is about as 

 strongly developed as in C. tan. These short forms of fusaniana 

 approach C. gotlschei Mlldff., differing chiefly in the separation of 

 the superior and spiral lamella-. In C. gottschei the superior is 

 continuous with the spiral lamella. This is also the case in C. tan. 



The clausilium of C. fusaniana differs from that of C. tan in 

 having the apex near the palatal margin, not symmetrically rounded, 

 as in C. tan. 



This was the only species of Clausilia found on Quelpart Island 

 by Mr. Kuroda. 



Macrochlamys quelpartensis n. sp. 



The shell is perforate, moderately depressed, capacious, very 

 thin and fragile, subtransparent, yellow, with a white sutural line ; 

 the base paler, more transparent. Spire low-conic, its width con- 

 tained in the diam. of the shell about 1.7 times. Whorls 5'(, rather 

 slowly increasing to the last, which is much wider, and rounded 

 periferally. Sculpture of very close, microscopic wavy or crimped 

 spiral lines, wanting on the first whorl, becoming much weaker on 

 the last half or more of the last whorl. Aperture large, broadly 

 lunate. 



Alt. 1 1.8, greater diam. 17.3, lesser 15.3 mm.

This fine species has more whorls than M. perfragilis, and 

 differs in minute sculpture. It is less depressed than M. subrefecta.
