practically harmless in the southeast. Further zoogeographic research will 

 undoubtedly show this gastropod to be more abundant and widespread here than 

 it now appears . 



North Carolina. Hackney (1944) lists drills as extremely common around 

 Ostrea, Pearse (1951) found them in the Bearfort Fstuary. Chestnut and Fahy 

 (1953) and Chestnut /pers . com } in 1954 fmdU. c inerea common in all the sounds 

 from the Spi'th Carolina line to Pamlico Sound, especially near the inlets. In 

 Lockwood Folly Paver Brunswick County, three sample plots yielded 13 

 Urosalpi nx per square yard,, and m Saucepan Creek,, in the same county, a 

 concentration ranging from 9 to 106 drills per square yard. A single cluster 

 of serpulid tubes collected in New River in April yielded 21 lirosalpinx . From 

 the piling at the Institute of Fisheries Research pier in Bogue Sound Chestnut has 

 taken as many as 120 drills above the low water mark from a single piling. The 

 writer has also found high concentrations of drills in the vicinity of the pier . Chestnut 

 finds the drills present in some abundance around Pivers Island and at Cape Lookout, 

 and plentiful in the upper part of Core Sound, where they apparently appeared when 

 Drum Inlet broke through during the storm of .1953. In. Pamlico Sound itself there 

 are few Urosalpin x except in the proximity of the inlets . Chestnut reports only an 

 occasional drill in the western half of this sound in the last 6 years. He has also 

 dredged them off Cape Lookout on the edge of the Gulf Stream 



S outh Carolina . There are conflicting reports as to the early distribution 

 of Urosal p inx here . In 1890 Dean said it occurred rarely, and in 1913 Mazyck 

 stated it was abundant Galtsoff et al (1937) found them only sparingly. The most 

 recent detailed and accurate information comes from Lunz (pers . com ) „ In a 

 preliminary survey of the coastal waters from Santee River southward to the 

 Savannah River in 1935., he found U , ci nerea all along this coast, but approximately 

 twice as abundant in the northern half. In 1938 he observed more drills in Harbor 

 River than in any other river of comparable size in the state ; concentrations up to 

 36 large drills per square yard at the mouth of the river. During the last few 

 years he has noticed an unusual increase in the abundance of the drill at the lab- 

 oratory dock at Bears Bluff, while in other areas in the state he finds Urosalpinx 

 widely but irregularly distributed and relatively scarce, certainly as compared 

 to the concentrations reported by others in Chesapeake Bay. No explanation is 

 known for the spotty distribution . Lunz believes the general paucity of this mollusk 

 may be explained by the practice in his state of growing the vast majority of oysters 

 intertidally . Andrews (pers. com.) suggests that the presence of extensive areas 

 of soft mud may further limit distribution of the drills. 



Georgia . Galtsoff et al (1937) report that Urosalpinx: occurs only sparingly 

 here , More recently the staff at the Marine Biology Laboratory of the University 

 of Georgia on Sapelc Island report that the drill is very abundant below the low tide
