CRAYFISHES. 397 
Carolina.’ It thus appears that Mr. Mooney’s crayfish came from a region not 
far remote from the type locality of C. carolinus. 
In this specimen (U. 8. N. M., No. 14,314), which displays the normal fea- 
tures of C. carolinus, as I believe, the rostrum is narrower than in C. dubius 
and less quadrangular in outline; the anterior process of the epistoma is much 
_ broader and more triangular in outline, the sides converging much more between 
the base and the truncated anterior angle; the carpus is armed with a prominent, 
acute, internal median spine, immediately behind which and at a little lower level 
lies a very small spiny tubercle; posteriorly to this, not far from the inner articu- 
lation with the merus, lies another distinct spine, smaller than the internal 
median spine; the lower face of the carpus bears one tubercle about half-way 
between the internal median spine and the outer articulation with the propodus; 
the lower face of the merus shows the biserial arrangement of spines as in C. 
dubius, as many as five or six spines adorning the external edge of the segment; 
the distal segment of the outer branch of the last pair of abdominal appendages 
is shorter and broader ( less oval in contour) than in C. dubius. The living color 
of this specimen, as is shown by a MS. note accompanying the specimen, was 
red, the color of C. dubius also. 
A large number of specimens in the U. 8. National Museum collected at 
various places in the southwestern part of West Virginia (Nos. 28,591—28,596, 
28,598-28,600, Horsepen Creek, War Creek, Baileysville, Lashmeet, Barranche 
Creek), agreeing in most respects with the typical C. dubiws from northern West 
Virginia and Pennsylvania tend to develop the accessory carpal spines and 
tubercles of C. carolinus. 
Three specimens (male, form I.) in the U. 8. National Museum, No. 
22.386, from a tributary of Stone River twenty miles from Columbia in cen- 
tral Tennessee are interesting. They agree in most respects with C.c. dubius, 
but the rostrum is a little narrower, with more convergent margins, the rostral 
acumen is less abrupt, and the outer border of the hand is rounded off with- 
out much indication of serrature. In these regards the specimens agree with 
the typical carolinus; the carpus, however, is very smooth, bearing no spines 
except the internal median, as in C.c. dubius. The outer inferior row of spines 
on the merus is present, though slightly developed. The branchio-cardiac 
lines are in closer contact than in any other specimens of this species that I 
have seen, reducing the areola to a narrow line.
