REMARKS: 
This species, the Red Crawfish of the mountain regions, occupies, next to C. 
propinquus, the smallest area in this state. Its morphological characters are very 
uniform, not only in this state, but also in the neighboring parts of West Virginia 
and Maryland. The chief variations, as already mentioned in the description, are 
found in the armature of the chelipeds, but they keep within comparatively narrow 
limits. The rostrum, which is quite variable in C. bartoni, is here very constant, 
only the degree of convergence of the lateral margins and the length of the acumen 
varying to a certain extent, (See Pl. XX XIX, fig. 8a and 3b.) Of course, we must 
disregard monstrosities, under which head I place two cases, (from Dunbar and 
Parsons), where the rostrum has almost no acumen at all, being rounded off apically. 
The armature of the meropodite and carpopodite varies as described above ; the 
carpopodite in particular showing a various number of tubercles, though they never 
become spiniform as in C. monongalensis. ‘The lower outer margin of the merop- 
odite has always more than one spine, when spines at all are visible, which is gen- 
erally not the case in very young individuals. 
“This locality needs confirmation, see Ortmann, 1905b, p. 135. 
25 This species is abundant in certain parts of Somerset and Fayette Counties, Pa., and well known to the natives- 
I have seen chimneys in abundance at Confluence, Somerset County, which undoubtedly belong to this species, but was 
not able to secure specimens, my time being limited. I have seen a specimen at Flanigan, 4 miles north of Somerfield, 
Fayette Co., and one from Humbertston, Fayette Co. (O. T. Cruikshank coll.). Reports received from farmers, always 
emphasizing the red color and burrowing habits of the crawfish in question, are the following : Great Meadow Run, 
west of Ohiopyle, Fayette County ; Millrun, Fayette County ; Ursina, Somerset County ; Salisbury, Somerset County. 
26 These specimens (collected June, 1893, and, according to Professor Moore’s recollection, dug out of holes) agree 
in all essential poipts with our material, only the rostrum is narrower.
