CONUS DADCDS Bruguiere. Shell orange or 

 carrot color, indistinctly banded, turbi- 

 nate in form with a low spire; spiral sculp- 

 ture present. 



Fossil specimens have been col- 

 lected in the Caloosahatchee beds of Flori- 

 da and it possibly may still be living near 

 the Florida Keys. Length 1.5-2 inches.

CONDS NEBULOSDS Solander. Cloudy Cone. 

 Shell solid, turbinated; zones of brownish 

 color crossed by fine spiral lines of 

 slightly darker shade, these lines becom- 

 ing dots or dashes of white and dark below, 

 toward the base becoming granular; spotted 

 with white irregularly upon surface; blunt- 

 ly crowned with short tubercles at the 

 shoulder; interior mostly whitish. 



This very beautiful shell is appar- 

 ently unrecorded from the United States. 

 Several specimens collected upon the Flori- 

 da beaches during the winter of 1935-1936 

 have been called to the writer's attention. 

 The fine shell illustrated was secured at 

 Fort Lauderdale by W. A. Royce. Another 

 worn specimen has been reported by Dr. B. 

 R. Bales from Pelican Shoals, about eight- 

 een miles northeast of Key West. Tryon 

 reports the species as occurring in the 

 West Indies and adjacent coasts of North 

 and South America.

Family Turridae (Turrltidae ) 



Shell fusiform, 

 spire elevated, canal 

 long and straight; slit 

 on outer lip, near su- 

 ture, an opening for ex- 

 cretions and shown in 

 Fig. 51. 



Animal with sinus 

 upon right margin and 

 corresponding with slit 

 in shell. A poison 

 gland is often present 

 and used in connection 

 with the radula. The

presence of this gland, together with the 

 notch in the shell, indicate affinity with 

 the Conidae. 



The species are extremely numerous, 

 also difficult to define and classify. In- 

 dividuals are usually few in numbers. Many 

 have been described from solitary examples 

 and a considerable number inadequately il- 

 lustrated, if at all. 



GENOS TURRIS Roedlng 1798, Pleurotoma 

 Lamarck 1799 (TOWER SHELLS) 



TURRIS VIRGO Wood (T. alblda Perry). Color 

 whitish; about five prominent raised spiral 

 ridges which are most conspicuous near the 

 periphery; additional, similar, closer ones 

 below; pairs of finer ridges between some 

 of the larger ones; suture well impressed; 

 canal long, narrow. Length 2.5-3.5 inches. 

 Depth range 26-150 fathoms. 



A single example, occupied by a 

 hermit-crab, was taken in Lake Worth, Flor- 

 ida. In the West Indies it lives in com- 

 paratively shallow water.

A very elegant group of deep-water 

 shells which also occur in the Eocene fos- 

 sil beds at Jackson, Mississippi and also 

 probably in Europe.

 the anterior portion of the whorls is cov- 

 ered with graniilose spirals, one more prom- 

 inent than the rest in front of which the 

 suture coils; sinus comparatively short, 

 banded outside by an elevated keel. The 

 spines are very small and curved toward the 

 apex; nucleus brownish, glassy and with one 

 keel. Length 27 mm.
