470 VARIATION AND ZOOGEOGRAPHY OF LIGUUS IN FLORID 



After entering the canal at the head of Biscayne Bay hammock land '

 pines farther in and then probably the everglades. e Cana1, 



Fort Lauderdale, New River, about 24 miles (as the crow flies) north of M' ' 

 There is hammock on both sides of the river about a mile below the town ^

 apparently the northern limit of Liguus on the east coast of Florid

North of this we made inquiry of the inhabitants along the canal, where 

 hammock land was in sight, but in no case had Liguus been seen by them 



Around the southern end of Lake Worth there is much fine hammock where 

 the vegetation seemed to be perfectly adapted to Liguus, but a careful search by 

 my party yielded no evidence of their presence there, either in the trees or on the 

 ground. Glandina, etc., are numerous. At Palm Beach a dealer in shells told 

 me he had sold many of the Liguus from Miami, but had found none around 

 Lake Worth. A number of living ones from Miami which he had liberated in 

 the hammock at Lake Worth did not survive. 



[Mr. Moore was repeatedly told of a "blue snail" to be found in hammocks 

 on the lower keys, especially on Pine Key; but although special search and 

 inquiry was made on every key visited by Mr. Raybon, Messrs. Brown and 

 Fowler, and by Mr. Simpson and myself, none was found. The only "blue" 

 snail to be found was Janthina, which is sometimes carried there by a hermit 

 crab which has a large violet claw of the same tint as the shell. As this crab is 

 common in the hammocks, it seems likely that the widespread tradition of a 

 "blue snail" may refer to Janthina.]
