line in the immediate vicinity of the island. Nothing is known about the 

 distribution or abundance of the drill elsewhere in the state (Pomeroy, per.com,). 



Florida . As early as 1874 Verrill and Smith stated that Uro salpinx was 

 present along northeastern Florida and on the west coast in Tampa Bay. Between 

 1881 and 1888 C, Jobmson (1890) commonly found it on oysters at St. Augustine. 

 Ruge (1898) wrote that it was not found in this state; he did not list specific areas 

 and hence may have been speaking of regions other than those from which the 

 drill has been reported. 



Northern Coast of the Gulf of Mexico . Apparently U . cinerea doe s not 

 occur here. Humro (pers . com.) in the Alligator Harbor area : Tallahassee, and 

 Butler (pers. com.) m the Pensacola region ; have never encountered it. Nor has 

 A. E, Hopkins (pers. com.) seen it along the Gulf from Apalachicola, Florida, 

 to Corpus Christi, Texas, Hedgpeth (1953) also notes that this muricid is unknown 

 in the living fauna of the area . 



Bermud a Federigbi (1931c) erroneously extended the modern range of 

 U. cinerea to this island on the basis of a reference by Arey and Crozier (1919). 

 Close examination of this paper reveals only that chitons were drilled by oyster 

 drills whose scientific name was not given. Verrill (1902), among others, makes 

 no mention of U. cinerea either as a native or as an introduced species on the island. 

 And Haas (pers . com . ) who studied the mollusk fauna of Bermuda for some time, 

 never found U. cinerea there, nor knows of any earlier or later record of the species 

 in the Bermuda, group . The writer concludes that the drill of Arey and Crozier was 

 another species . The mention by Galtsoff et al. (1937) of U. cinerea in Bermuda 

 (no reference is cited) is probably taken from Fedenghi s (1931c) report. 



Western Coas t of North America 



There may be some question as to the exact role which man has played in 

 the dispersion of U. cinerea along the east coast of North America principally 

 because of the fossil distribution of the species in this region, However the trans- 

 portation to and subsequent distribution of this snail along the western coast of 

 North America is a clear demonstration of unwitting human collaboration in the 

 spread of an undesirable species The introduction of Uro salpinx to English waters 

 is an equally striking example . 



California . Soon after the opening of direct rail communication between 

 the east and the v/est coast, the firm of A. Booth & Co. transported three carloads 

 of large live eastern oysters to San Francisco . This is reported as the first ship- 

 ment of live oysters from the Atlantic coast. Walter (1910) states that these
