MILLIPED GENUS CHEROKIA — HOFFMAN 257 



Distribution: The Great Smokies and perhaps also the Unicois 

 along the boundary of North Carolina and Tennessee, generally above 

 an elevation of 3,000 feet. The northern known locality is Mount 

 Sterling; the easternmost, Soco Gap. Whether ducilla occurs north of 

 the Pigeon River remains to be determined. Approximate!}' 72 pre- 

 served specimens, representing 14 collections, have been studied, as 

 well as several dozen observed in the field but not retained. All of 

 the material listed is in my collection.

Type specimens: Male holotype and two paratypes, USNM Myria- 

 pod type No. 2532, (Diplopod No. D-512),from a bluff on the Caney 

 Fork River, one mile northeast of Rock Island, Warren County, Ten- 

 nessee, collected on May 9, 1951, by Leslie Hubricht. 



Diagnosis: A subspecies of Cherokia georgiana in which the scapu- 

 lorae are completely marginal, concealing the anterior surface of the 

 paranota when seen in dorsal aspect (fig. 3, a). In details of structure 

 agreeing almost completely with the detailed description given for the 

 nominate subspecies. 



Variation: The material examined shows very little structural var- 

 iation. The size is remarkably uniform, the length ranging from 32 to 

 35 mm. in most of the specimens and the width from 8.0 to 9.5 mm. 

 The largest male seen is from Campbell County, Tennessee: 37.5 mm.
