SYKES : MALACOLOGICAL NOTES. 



the umbilicus not being so open. From A. aequivoca (Pfr.), which it 

 most nearly resembles in colour, it may be separated by the size, the 

 more elevated form, and the thickened but not reflected lip. A. 

 tuhularis (Morel.) is about the same size, but the shape is different 

 and A. x)}jramidalis is not marked by the last whorl being so much 

 drawn to one side. 



The known species of Acroptychia appear to be as follows : A. 

 aequivoca (Pfr.), 1857. (Synonym A. manicata, Cr. and Fisch., 1882.) 

 A. alhocinda, E. A. Smith, 1893. A. metablefa, Cr. and Fisch., 1874. 

 A. notabilis, E. A. Smith, 1892. A. rdiculata (Adams and Reeve), 

 1848. A. tuhularis (Morelet), 1861.

Fig. 8. — Claicsilia granulosa, n. sp. Fig. 9. — Sculpture of same. 

 Fig. 10. — Posterior view of penultimate whorl. 



A single dead shell of this handsome species was presented to me 

 some years ago by Mr. G. B. Sowerby ; I have delayed describing it 

 in the hope either that I might obtain better material, or that some 

 other person might be in a more fortunate position. 



The sculpture appears to be due to both revolving and transverse 

 striae, which produce a decussated appearance, the spirals becoming 

 comparatively much weaker on the lower whorls.
