30 JAPANESE MOLLU8K8, BUCCINID^E. 



lirate, and closely and strongly plicate ; plicae becoming partly or 

 wholly obsolete on the body-whorl, which is very indistinctly or not 

 at all shouldered, and runs upward somewhat toward the aperture, 

 causing a narrow, small posterior channel. Aperture shaped as in 

 S. fuscolineata Pse. but wider, the inner lip smooth, its edge raised 

 and free ; outer lip with a wide yellow internal border, inside of 

 which it is thick, lirate and white. Anterior canal strongly re- 

 curved, short. Alt. 46, diam. 25 mm. Oblique alt. of aperture 

 29 mm. 



Allied to S. longirostris Dkr., but less elongated, with more 

 strongly plicate spire and different aperture. I cannot see that any 

 of A. Adams' un figured species agree with the specimens before me. 

 The spire is longer and more plicated than in S. fusoides Reeve, and 

 the canal more recurved.
