pure white or slightly greenish, with from one to seven spiral narrow 

 green or bronzy lines on the last whorl that may extend to the 

 penultimate one; aperture large; outer lip thin; columella straight. 



Length 48, diameter 27 mm.; length 42, diameter 23 mm. 



Great hammock near Fort Lauderdale ; hammocks along the outer 

 shore opposite the town and to the northeastward; south side of 

 New River near its mouth; hammock about a mile south of Fort 

 Lauderdale; hammock north of Arch Creek, where both typical 

 specimens and those hybridized with fasciatus were found. A form 

 nearly typical was taken just south of Little River stream. 



A well-characterized subspecies, being thin, short, and inflated, 

 highly polished and glassy, usually with a decided peripherial angu- 

 lation. Sometimes the spiral lines are brilliant green, or they may 

 be bronzy; they are rarely wholly wanting. It has been found in 

 the shore hammock more than 2 miles north of Fort Lauderdale, 

 and this is the most northern authentic locality for Liguus in the 

 State of Florida; I have a specimen of Liguus from the village 

 of Jamaica, Cuba, which is very close to septentrionalis, the only 

 difference being that the Cuban shell is a little more solid and has a 

 slight ledge within the aperture.

Shell usually small to medium size, inflated, and having decidedly 

 rounded whorls, subsolid to solid; axial region pure white, the 

 columella ordinarily strongly twisted and truncate; there is in the 

 more solid shells a decided ledge or shoulder just inside the aperture; 

 color white, greenish, or yellowish white, usually dull; often there 

 are a few green or bronzy spiral lines and sometimes a dull, broad, 

 yellowish band above and below the periphery. 



Length of a shell from the type lot 40, diameter 23 mm. ; length of 

 a large shell from Middle Cape Sable 55, diameter 30 mm. 



Lossmans Key on the southwest coast to Middle Cape Sable; 

 Rodgers River; John Douthett's place near Flamingo. 



A peculiar form and somewhat variable for one having such a 

 limited distribution. Most of the shells are short, solid, with 

 rounded whorls ; but others which I refer to this are somewhat lighter 

 in build, are more lengthened, and have less decidedly rounded 

 whorls, and these usually do not show the strong inside ledge. But 

 the two seem to intergrade. Dr. Edward Mercer and I found an 

 extensive colony in an isolated hammock at Middle Cape Sable where 

 some specimens were quite large and had the last whorl flattened
