Key, some of them being considerably larger than those from El- 

 liotts Key. Pilsbry, who has seen numerous perfect shells, says that 

 there is a faint yellow sutural line and usually some yellowish olive 

 green, chiefly basal lines.

1920. Liguus creruitus luteiis Simpson, Proc. Biol. Soc. Washington, vol. 33, 

 p. 123. 



Shell varying from small to large and from thin to solid; axial 

 region white, with the columella generally twisted or subtruncate; 

 whorls somewhat rounded, with the sutures well impressed; color 

 varying from straw or pale yellow to deep yellow or orange, lighter 

 to white on the earlier whorls, sometimes having from one to several 

 narrow dark or green spiral lines on the last whorl at or above the 

 periphery and fainter lines on the base. 



Length of type 63, diameter 18 mm.; length 38, diameter 18 mm. 



Vaca group of the Upper Keys; east end of Upper Matecumbe, 

 one specimen; Kep Largo (C. E. Saxton), a fine j^oung specimen; 

 rocky ridge on the south and southeast mainland from Long Pine 

 Key east and north to Dania ; Pinecrest, very brilliant. 



In most shells there is a sort of ledge inside at the aperture com- 

 posed of the dull white matter of the interior, and the outer lip is 

 thin and darker colored. Some of the specimens from Key Vaca 

 have the last whorl brilliantly tinted with orange, and I have shells 

 collected back of Larkins and about Dania, the latter locality being 

 near the northern limit of Liguus on the east coast, which are very 

 close to the Vaca material. It is an abundant form, and as I have 

 remarked, it is the first to inhabit the incipient hammocks of the 

 great rocky ridge. In some of the larger hammocks it is the only 

 occupant.

Shell medium to large sized, thin to subsolid, somewhat shining; 

 whorls varying from flattened to somewhat rounded, pure white, 

 with a broad, pale yellow spiral band above the periphery and 

 another below it; columella twisted. 



Length of type 33, diameter 20 mm.
