only, while in others many dark specimens occur also. The more 

 elaborately-marked forms, such as Vic? and Vie are rave at Miami, 

 the forms VI and Via greatly predominating. 



Cape Sable, S.-E. Florida (Simpson, Willcox). White, with pink 

 apex and columella, the later half of the body-whorl with a pink 

 peripheral line and numerous light greenish lines ; solid and strong, 

 with the columella either heavy and strongly truncated, or the trun- 

 cation scarcely noticeable (pi. 59, fig. 96, coll. by Willcox). Simpson 

 writes : u Some of the shells marked with a broad spiral band of bril- 

 liant orange, and on one shell the band was green." 



Goodland Point, Lee Co., on the west coast, about 40 miles south 

 of Charlotte Harbor (Simpson, Hemphill). This is the most north- 

 ern point from which the species is known, though Mr. Simpson 

 mentions a report of its occurrence on Sanibel Island. It ascends 

 decidedly further on the west than on the east coast. The shells 

 collected by Hemphill are white with the apex and columella pink, 

 last one or two whorls with a broad yellow zone or two, and some- 

 times numerous yellowish-olive lines toward the end of the last whorl. 

 Simpson mentions them as either pure white or slightly marked with 

 greenish or brown lines on the body-whorl. It occurs in abundance. 



It will be obvious from the foregoing that certain color-patterns are 

 locally restricted ; but until many more of the keys are explored and 

 ample series collected with data on the stations, etc., no definite con- 

 clusions on the distribution of the color-varieties can be formulated. 

 The exact habitats of some forms, such as the solidus of Say, are 

 unknown. 



L. BLAINIANUS (Poey). PL 55, figs. 51, 52, 53. 



Shell oblong-turreted, rather solid. Cream -white or yellowish- 

 white, with five black-brown spiral bands : the upper one a mere line 

 below the suture, the second and fourth wide zones more or less 

 broken by reddish or yellow streaks, the third or peripheral narrower, 

 continuous, and the fifth band encircling the columellar region or 

 forming a columellar patch. The first, third and fifth bands are 

 sometimes replaced by diluted purplish or purple-brown bands (fig. 

 53), and the degree of maculation of the two main zones varies 

 within wide limits. Surface smooth. Whorls 7^, the apex blackish 

 at the tip when not removed, several whorls following reddish, with 

 a pale subsutural border.
