ART. 20 FLORIDA TREE SNAILS SIMPSON 31 



LIGUUS FASCLA.TUS ALTERNATUS Simpson 



Plate 2, fig. 1 



1920. Liguus fasoiatns alternatus Simpson, Proc. Biol. Soc. Washington, vol. 33, 

 p. 123. 



Shell medium sized, rather solid, with bright pink axial region; 

 color white with a broad, spiral, siipraperipheral band consisting of 

 alternating light and dark axial chestnut lines and bars; there is 

 sometimes a faint, narrow peripheral reddish line and there is a 

 broad band at the base similar to the wide one above; columella 

 straight or very slightly twisted. 



Length of type 45 ; diameter 24 mm. 



Timb's hammock; Black Creek, Paradise Key, all in Lower Dade 

 County, Fla. 



This form, which is probably a sport from castaneozonatus seems 

 to be confined to a few localities in the south end of the mainland 

 of the State. Certain shells have the broad bands replaced in places 

 by white or yellowish. 



LIGUUS FASCIATUS ROSEATUS Pilsbry 



Plate 2, fig. 7 



1912. Liguus fasciatus roseatus Pilsbry, Journ. Acad. Nat. Sci. Philadelphia, 

 ser. 2, vol. 15, p. 448, pi. 38, figs. 11, 11a, 116, 13, 15, 19, 19a. 



Shell subsolid to solid, with somewhat rounded whorls; axial 

 region pink to purplish; surface white, with a broad supraperiph- 

 eral band of yellow, brownish yellow, or orange; rarely this band is 

 overlaid with a few green spiral lines; there is a similar basal band 

 and occasionally a faint narrow reddish peripheral line; parietal 

 wall pink or tinted purplish, darker colored along its outer edge, 

 sometimes having deep pink streaks ; columella twisted and subtrun- 

 catc in heavy shells, thinner and straight in less solid ones. 



Length 45, diameter 25 mm.; length 40, diameter 21 mm. 



Entire area occupied by Liguus in Florida except the extreme 

 northeast portion, the Lower Keys, and the central part of the 

 Upper Keys. One specimen from Pinecrest. 



This is the most widely distributed form of Liguus in Florida, 

 and it is not exceedingly variable. Some of the shells are very 

 beautiful, the darker bands being a brilliant orange. Rarely a few 

 dark spiral lines on the last whorl. 



LIGUUS FASCIATUS LINEOLATUS Simpson 



Plate 2, fig. 8 



1920. Liguus fasciatus lineolatus Simpson, Proc Biol. Soc. Washington, vol. 33, 

 p. 125. 



Shell subsolid to solid, with somewhat rounded whorls ; axial area 

 pink or purplish red; surface whitish, flesh colored, or yellowish,
