subspecies shows the speckled condition; however, neither do the 

 majority of the population of C. I. longulus. 



Specimens examined. — I have examined approximately 100 col- 

 lections from 78 locaUties in Virginia, West Virginia, and North 

 CaroUna, including adults of both sexes, both forms of male, and 

 juveniles, representing a minimum of 500 specimens. I have no 

 authenticated records of this subspecies having been taken from 

 Tennessee (see Ust III, p. 7). 



Geographic distribution. — It would appear that C. I. longulus 

 is Hmited geographically to the James, Roanoke, and Yadkin River 

 systems of the Atlantic drainage (maps 1,2). The southernmost record 

 is from the Yadkin River drainage, Wilkes County, N. C. (map 2, 

 no. 92). The northern Hmit seems to be in the headwaters of the 

 James in Highland County, Va., west of the Blue Ridge (map 2, nos. 

 51-53) and in Greene County, east of it (map 2, nos. 43-50). It 

 is found as far east as the Rivanna River (James drainage) and its 

 tributaries (map 2, no. 36) but does not, from my data, extend west 

 into or beyond the New River drainage or north into the Shenandoah 

 as some records erroneously indicate (see lists I, II). 



A hst of all locaHties and drainage systems in which C. I. longulus 

 has been found has been deposited with the U.S. National Museum.^ 

 Many collections incorrectly labeled as C. I. longulus must herewith 

 be removed and reassigned to other taxa. 



Because the labels for his type specimens had been lost, Girard 

 (1852, p. 90) cites the locahty only as "Middle States." Ortmann 

 (1931, p. 118), Usting the first of Faxon's reported localities (1S90, 

 p. 623), designates "the first exact locality ... as a supplementary 

 type-locaUty . . . South River, Waynesboro, Augusta Co., Virginia. 

 (Faxon) (to Shenandoah and Potomac)." This choice of type locality 

 seems inadmissible, for no member of the species C. I. longulus has 

 been found since in the Potomac drainage. Neither Girard (loc. cit.) 

 nor Hagen (1870, p. 78) mentions the presence of a lateral spine on 

 the type specimen, but Hagen does note that between the fingers there 

 "is a large bunch of hairs." From this combination of characteristics, 

 it would seem more likely that Ghard's type came from the James 

 drainage, east of the Blue Ridge. 



Synonymical reassignments.— On the basis of available data, 

 many collections (hsted below), previously recorded as C. I. longulus, 

 now must be reassigned either to another species or to the subspecies 

 C. longulus longirostris or C. I. chasmodactylus. Inappropriate names 

 and/or localities are so indicated in the synonomy.

 Museum, where these data are on file (no 254736) in the office of the Registrar.
