This whelk seems to be related to tlie smaller, thinner and 

 smoother B. morchiamim (Fischer), but the two are quite distinct. 

 In some specimens the coarser spirals are all low, subequal and 

 almost evenly distributed over the surface. As usual in Bucciimm, 

 the coarser sculpture is variable. Some specimens lack the thin, 

 greenish cuticle, being dull, creamy- ashen, like many arctic shells. 

 There is always a livid or puiplish worn sjiot in front of the aper- 

 ture. 



ON THE NORTHEENMOST HABITAT OF LIGUUS FASCIATUS ON THE 

 FLORIDA EAST COAST. 



BY CI.ARENCl-: H. JIOOKE. 



These snails at the present writing (1904), live in great abund- 

 ance at Miami, Dade Co., Florida. They were found by me in 

 small numbers at Arch Creek, about nine miles north of Miami. 

 Going northward I found them, here and there, along the banks of 

 New River, below Ft. Lauderdale about 24 miles, in a straight line, 

 north of Miami. 



North of this point inquiries were made along the banks of the 

 canal where " hammock " land (such as Liguus requires) is often in 

 sight, but in no case had the snails been seen by the inhabitants. 

 At Boca Raton, Dade Co., the hammock is not large, and much 

 undergrowth has been burned recently. We saw no living Liguus, 

 nor any of their shells on the ground. Glandina was present and 

 various shells of other kinds. 



Occasionally among the Keys, south and east of the peninsula, the 

 statement was made to me by persons I met, that occasional snails of 

 tiiis species had been seen by them as far north as Lake Worth. 



A number of inhabitants living about six miles south of Lake 

 Worth had never seen the snails. Around the southern end of Lake 

 Worth there is much fine hammock, where the vegetation seemed 

 expressly made for Liguus, but a careful search made by my party
