EXPLORATIONS OF THE ALLEGHANY REGION AND WESTERN INDIANA. 137 
5. Moxostoma rupiscartes Jordan & Jenkins. B., C., J., P., T. 
The speciiueus from tlie Catawba, Salnda, Ocmiilgee, and other rivers south of 
the Nense, hitherto referred to Moxostoma cervinum by Cope and by the writei', seem 
to belong to a distinct species, for which we have proposed the name of Moxostoma 
rupiscartes, the latter name in allusion to the vernacular name of “Jump Rocks,” by 
which the species is known in Georgia. It is closely allied to M. cervinum, differing 
chiefly in its smaller scales and more uniform coloration. It reaches a larger size; its 
lips are larger, and the form of its dorsal fln is somewhat different. It is very abun- 
dant in the Catawba, Pacollet, and all other large streams in the Santee Basin. It is 
less strictly confined to rapids, shoals, and waterfalls than is the case with M. cervinum. 
6. Campostoma anomalum (Rafluesqne). B., J., C. 
Rather common ; scales 52, 
7. Hybognathus nuchalLs Agassiz. C., J. 
Common. 
8. Notropi.s saludanus (Jordan & Brayton). J., P. 
Not rare. It may be that the southern form of this fish is a species distinct alike 
from the northern hudsonius and from the amarus of the Potomac. Comparison of 
numerous specimens shows the following results: 
The southern form, sahidamis, James River to Ocmulgee River, has the head 
notably longer (4^ in length in specimens from John’s River; 4f in specimens from 
Swift Creek) ; the snout is especially longer, projecting over the inferior month ; the 
snout about as long as eye, which is about 4 in head. Teeth 1, 4-4, 0, 
Var. amarus from the Potomac has head shorter and deeper (4^ to 4f in length); 
eye larger (3^ in head) ; caudal spot faint; teeth 1, 4-4, 0. 
’Var. hudsonius (specimens from Michigan City, Ind.), has the head still shorter 
(4^ in length); eye 3f in bead, as long as snout; snout blunt; mouth a little more 
oblique than in amarus or saludanus ; maxillary not to front of eye; teeth 2, 4-4, 1. 
Caudal spot jet black. 
Var. selene from Keweenaw, Lake Superior, has the head still shorter (4|- in body) ; 
mouth quite oblique, the premaxillary on level of lower part of pupil; snout f eye; 
maxillary reaching front of eye ; caudal spot jet black. Teeth 2, 4-4, 1 or 2. 
The extremes, selene and saludanus, certainly look like very distinct species, but 
the iutergradations are such that it seems safest to regard the whole series as varieties 
of one species, N. hudsonius. 
9. Notropis procne (Cope). C. 
Abundant in the Catawba, in the river channels ; not noticed in the other streams. 
10. Notropis chlorocephalus (Cope). B. 
Abundant in the clear, swift waters of Buck’s Creek. Green in life; dorsal and 
caudal red at base; sides of head and lateral band on sides red. Adult males with 
the whole body cherry-red, the back green, lower jaw not black. Allied to N. rubri- 
croceus. 
11. Notropis lutipinnis (Jordan & Brayton). F. 
Six specimens taken in the clear waters of Forest Creek ; hitherto known only 
from a similar locality on the headwaters of the Oconee, in Georgia. In life, pale
