THE NAUTILUS. 131 



specimens exactly typical occur at Ibuki, Omi. It is much less stri- 

 ate than japonica. In the specimens I have seen the surface is dull 

 from loss of the cuticle, which is evidently deciduous and very thin. 

 It varies in color from white or sulphur-yellow to deep crimson. 

 Some shells from Kotsuzan, Awa (Shikoku) having all other charac- 

 ters of reinii, have the last whorl covered with glossy cuticle like the 

 small form expolita. Reinii may prove to be specifically distinct from 

 H. japonica, and for the time being may be so considered. 

 The various forms may be tabulated thus: 



I. Shell distinctly striate or costulate (H. japonica}. 



1. Striation close and fine. 



a. Diam. 7 to 8 mm., typical H. japonica. 



b. Diam. 9 to 11 mm., H. japonica, var. from Harima. 



c. Diam. 15 to 16 mm., H. japonica var. uzenensis. 



2. Very coarsely ribbed; diam. 10-11 mm., H. japonica var. 

 echigoe.nsis. 



\\. Surface not distinctly striate (H. reinii). 



1. Surface dull, denuded of cuticle; diameter 12 to 15 mm., 

 typical H. reinii. 



2. Surface covered with a smooth, polished cuticle ; diam. 10 

 to 13 mm., H. reinii var. expolita. 



H.j. echigoensis is a new variety from Omimura, Echigo, types no. 

 84384, A. N. S. P., from no. 575a of Mr. Hirase's collection. It is 

 strongly and coarsely ribbed. 



A NEW CONUS FROM THE TERTIARY OF FLORIDA. 



HY T. H. ALDRICH. 



Conus waltonensis n. sp. 



Shell medium in size, substance rather thin ; spire elevated, with 

 nine whorls, including the apex, which is rather sharp, profile of 

 spire slightly broken by a shoulder just above the suture on each 

 whorl, the suture impressed, each whorl of the spire concave, and 

 marked by numerous curved lines; periphery sharp; body whorl 

 below the keel in some specimens over one-half smooth, then below 

 this bearing two or three spirals of evenly-spaced nodules without 

 any grooves between, gradually changing to rows of nodules on bands
