did not differ much in size. 



Specimens from Key West, Summerland Key and Boca Chiea an- all dead 

 and none of them show traces of color- pattern. They appear to be like the shells 

 of No-Name and Pine Keys. So far as the material goes, the same varioolored 



species appears to have extended over the Keys from Key West to No-Name 1 

 It is probably extinct now except on Big Pine and No-Name K Unfortu- 



nately, the weather was very dry when Mr. Simpson and 1 were on the lower key*. 

 The Liguus were in hiding, so that few specimens could be found. They must 



be sought in the rainy season. 



The following material has been examined, exclusive of dead shells too old 



to show color or pattern.

The localities mentioned are indicated on the map, Pi. XL, drawn by Dr

the mainland coast about fifteen miles north of 



There is good evidence that Liguus formerly extended further north on the 

 west coast than its present range. Mr. E. V. Stephens, postmaster of Marco 

 and a dealer in shells, etc., states that eighteen or twenty years ago (about 1884-6) 

 he found a few of them at Little Marco, and at Gordon's Pass. This past is just 



south of Naples, a place on 



Marco, by water. . 



Mr. J. W. Russell, of Russell's Key (where Liguus is found in abundance 

 at the present time), who for two years has lived at Naples, after careful search 

 and inquiry, reports that Liguus is not found at Naples at the present time (1904). 

 Naples is in the same latitude as Fort Lauderdale, New River, where I found 

 what I believed to be the northernmost specimens of Liguus on the east coast
