AET. 20 FLORIDA TREE SNAILS SIMPSON 33 



LIGUUS FASCIATUS LIVINGSTONI Simpson 



Plate 2, figs. 3 and 9 



1920. Liguus faadatua Uvingstoni Simpson, Proc. Biol. Soc. Washington, vol. 33, 

 p. 124. 



Shell variable in size, solid, with rounded whorls; axial region 

 purplish pink to deep purple, the parietal wall often showing deeper- 

 colored streaks; surface white, usually smoky, greenish or pale yel- 

 lowish green on the last whorl, with from a few to several spiral 

 green lines on the last two whorls but wanting such markings at the 

 periphery ; columella straight or twisted. 



Length of type 42, diameter 24 mm.; length of large shell 58, 

 diameter 27 mm. 



Fort Lauderdale (Squires), south along the rocky ridge to Long 

 Pine Key in the Everglades, rare at the lower end of its area. I have 

 a shell of fasciatus from Luis Lazo in Western Cuba 56 mm. in length 

 that is very close to others that I got on cypress trees at the head of 

 the Miami River, Fla. It agrees in size, color, markings, and weight 

 to the last detail. The species Uvingstoni differs from Uneolatus in 

 having colder colors, in usually becoming darker toward the aperture 

 and the more numerous green spiral lines which are absent on the 

 periphery, also in lacking a reddish peripheral line ; besides it has a 

 different distribution. Recently a specimen of this has been found at 

 Fort Lauderdale by Carl Squires. 



LIGUUS FASCIATUS MIAMIENSIS Simpson 



Plate 2, fig. 4 



1920. Liguus fasciatus miamien-sis Simpson, Proc. Biol. Soc. "Washington, vol. 

 33, p. 124. 



Shell usually small to medium size, subsolid, with rounded whorls ; 

 axial region light to deep purple; body of the shell whitish, the 

 fourth, fifth, and sometimes the sixth whorls having a wide, median 

 band consisting of irregular brown blotches often on a yellowish 

 ground, and this usually ends abruptly on the last whorl. The latter 

 part of the last whorl ordinarily has a number of narrow, spiral 

 green lines which extend to the aperture. 



Length 46, diameter 23 mm. ; length 38, diameter 38 mm. 



Ojus south and west along the rocky ridge to Paradise Key. 



Doubtless a hybrid with some of the characters of castan-eozonatits. 

 I have a shell from Nuevitas, Cuba, which though larger and more 

 elongated has the same general markings as this form. Some speci- 

 mens of 7mamiensis have a reddish peripheral line, while others 

 scarcely show a trace of it. It is quite likely that the ancestors of 

 this form drifted from Cuba and became established in the great 

 Miami hammock.
