LIGUUS SOUDUS PSEUDOPICTUS Simpson 

 Plate 1, fig. 9 



1920. Liguus soUdus pseudopictus Simpjson, Proc. Biol. Soc. Washington, vol. 

 33, p. 122. 



Shell large, somewhat elongated, thin, with the axial region wMte^ 

 with slightly rounded whorls and well-impressed sutures, grayish 

 white to greenish yellow, sometimes cream colored and having oc- 

 casional bluish axial smears, the third, fourth, and sometimes the 

 fifth and sixth whorls often having zigzag brownish lines and 

 blotches; last whorl sometimes greenish-yellow with green, spiral 

 lines; there is a double row of sutural squarish brown spots from 

 columella thin and straight; texture glassy to porcellanous. There 

 is a form with broad, brown zigzag strigations. on the fourth, fifth, 

 and sixth whorls. 



Length of type 50, diameter 36 mm.; length of a large specimen 

 64, diameter 32 mm. 



Lower Matecumbe Key near the middle of the island. 



Undoubtedly derived from the form lignumvitae and analogous to 

 pictus from which it differs in its much larger size, its thinness of 

 shell, duller color, and white axial region. Occasional intermediates 

 connecting it with ligtviimvitae are found. The young shells have a 

 smoky peripheral band such as is seen in pictus. Some of the shells 

 are porcellanous but the majority are but slightly so and a few have 

 green spiral lines on the base. A form has broad, brown, zigzag 

 stripes. 



LIGUUS FASCIATUS MuHer 



1744. Liguus fasciatus Mijixeb, Verm. Terr, et Fluv., vol. 2, p. 145. 1774. 



Shell imperforate, oblong-conic, smooth, usually glossy and highly 

 painted, the colors being white, yellow, brown, green, orange, and 

 even scarlet ; whorls rounded ; axial region always wholly or in part 

 pink or purplish ; columella thin and straight to thick and twisted or 

 truncate. 



Entire island of Cuba; Cozumel Island; lower Florida along the 

 coast at ]\Iarco on the west to Fort Lauderdale on the east; Upper 

 Florida Keys. 



In a majority of the Floridian subspecies some of the earlier 

 whorls show brownish regular or zigzag lines or even blotches, such 

 markings being present in castaneus, testudineics, versicolor, castaneo- 

 zonatus, alternxi.tus, 7niamiensis, elegans, and occasionally in living- 

 stoni,' but they appear to have faded out in roseatiis, lineolahcs, and 

 ornatus. Without a doubt this color pattern which we see strongly 

 developed in Cuban shells of this species was one of the earlier char-
