Some of A. Adams' blanket "descriptions" might cover these 

 species, but none of them indicate the specific characters of either 

 of them. The sane judgment of scientific malacologists now de- 

 mands that a description shall describe. 



TURBINID^. 



Leptothyra rubra var. laevicostata nov. 



Shell depressed-globose, coral-red, with pale and red dots alter- 

 nating on the ribs. Whorls 4^, the last deeply descending anteri- 

 orly. Sculpture of about 8 rather strong, almost smooth spiral 

 ribs above and upon the I'ounded peripheral region, with one or 

 several fine threads in some of the interspaces; 8 to 10 smaller, 

 closer smooth ribs upon the rather flattened base. Alt. hardly 4, 

 diam. 5 mm. 



Northern shore of province Tango, western side of Hondo (M. 

 R. Gaines). Types No. 70,704 Coll. A. N. S. P. 



Specimens from Mr. Hirase, taken at Hirado, Hizen, vary 

 from coral-red to almost purple, and some of them are rather 

 larger with the .spire elevated, the largest measuring alt. 5.2, 

 diam. 5.5 mm. 



This form difiers from L. rubra (Dkr. ) in the smoothness of the 

 spiral ribs, which are not rougher than in the Mediterranean L. san- 

 (juinea (L. ), and in the smaller size, rubra measuring, alt. scarcely 

 6, diam. 6 to 6^ mm. In L. sangalnea the ribs of the base are 

 not noticeably smaller, as they are in all of the Japanese Lejito- 

 thyras I have seen. Perhaps this variety is what Dunker and 

 others have reported from Japan as sanrjainea L. 



AOMuEID^. 

 Acmaea heroldi var. signata Pils. PL XIX, figs. 10, 11. 



See p. 202. Types No. 80,497 Coll. A. N. S. P., from No.
