KEM.VRKS: 



This species, the Red Crawfish of the mountain regions, occupies, next to C 

 projiiiiqaus, the smallest area in this state. Its morphological characters are very 

 uniform, not only in this .state, liut also in the neighboring parts of West Virginia 

 and Maryland. The chicjf variations, as already mentioned in the description, are 

 found in the armature of the chelipeds, but they keep within comparatively narrow 

 limits. The rostrum, wliich is (piite varialjle 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 Pi. XX.Xl.X. fig. 3o. and 3/;.) Of course, we must 

 disregard monstrosities, under which lu'ad 1 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 jjarticular showing a various number of tubercles, though they never 

 become spiniform as in ('. vionoiujalcmh. The lower outer margin of the merop- 

 odite has always more lliaii one spine, when spines at all are visible, which is gen- 

 erally not the case in veiy young individuals. 



"This locality needs coiilinimtion, .see Ortinann, 1905b, p. 13.5. 



"This species is abundant in certain parts of Somerset and Fayette Conntics, Pa., and well known to the natives- 

 I have seen chimneys in abundance at Conlhiente, Somerset County, which undoubtedly helonn to this species, but was 

 not able to secure specimens, my time being limited. I have seen a specimen at Flnnigan, 4 miles north of Soniertleld, 

 Fayette Co., and one from llumbertston, F.iyctte Co. (O. T. Cruikshank coll. ). Reports received from farmers, always 

 emphasizing the red color and burrowing habits of the crawfish in question, arc the following : Great Meadow Run, 

 west of Ohiopyle, Fayette County ; Millrun, Fayette County ; Ursina, Somerset County ; Salisbury, Somerset County. 



'* These specimens (collected June, 1893, and, according to Professor Moore's recollection, dng out of holes) agree 

 in all essential points with our mateiial. only the rostrum is nairower.
