List IV 



(Other synon3miical records not fitting into lists I, II, III) 



Hagen, 1870 1. "A female type of C. longulus . . . differs from C. Bartonii in 

 having its hands smooth ... I think it is C. Bartonii" — 

 This specimen more logically belongs to C. I. longulus. 



Faxon, 1914 2. "I have seen an interesting lot of specimens (from above 

 Kanawha Falls) that combine the characters of C. b. 

 montanus and C. b. longulus. . . . These specimens are in the 

 U.S. National Museum, No. 23990, and in the Museum of 

 Comparative Zoology, No. 7401." — Having examined the 

 former collection, the present writer, although uncertain of 

 its specific status, excludes the above from the C. longulus 

 group. 



Coloration and color pattern. — Most C. I. longulus are con- 

 coloroiis, usually a browTi or green with shades of ivory to tan beneath. 

 A mottled pattern is kno\\Ti from two widely separated localities 

 (fig. 2c). One, the Swift Run, a tributary of the North Fork of the 

 Rivanna River (James drainage) in Greene County, Va. (map 2, no. 

 50) is entirely of the brown phase (orange to dark brown). The other 

 mottled pattern is found in some tributaries of the Smith and South 

 Mayo Rivers (Dan River to Roanoke drainage) in Patrick County 

 (map 2, nos. 65-70) ; these are variously colored within individual popu- 

 lations. Colors range from yellow orange through shades of green 

 and brown and, like the James River specimens, have their underparts 

 tinted ivory to tan. It would appear that the background color of 

 these mottled ''Roanoke longulus" is in shades of tan and that only 

 the mottling seems to vary. These two very similarly patterned and 

 colored populations of crayfish occur in streams almost 125 miles apart.
