Fig. 3. Geochronography of Noturus furiosus in the Neuse River drainage, 
North Carolina. Map shows virtually all known records of capture. Solid dots 
indicate capture sites, but not necessarily extant subpopulations. Offriver data 
are: year of collection(s) preceded by (1) solid dot if N. furiosus taken, (2) open 
circle if not taken, (3) asterisk if voucher material not available; following the 
year are (4) number of specimens taken (this number is separated by a comma), 
(5) the number of collections not yielding specimens (this number is separated 
by a semicolon), (6) a “?” indicating number of specimens unknown, and (7) a 
“+” sign indicating many individuals were returned to the stream. Numbers refer 
to collection of juvenile and adult specimens only. A. Eno River, B. Crabtree

with much of the stream bottom consisting of bedrock and large rubble. 
Capture of N. furiosus above the Fall Line is rare, and the Eno River 
record is at the extreme northwestern edge of the species’ range. 
Neuse River near Raleigh. — This is the type locality of N. furiosus 
where approximately seven specimens were taken in 1888, 1897, and 
1902. Four daytime visits to the Neuse River near Raleigh in 1982, 1983, 
and 1985 revealed large expanses of suitable habitat, but no madtoms 
were collected. The changes in the river near this site include the 
construction of a major reservoir (Falls Lake) upstream and pollution
