368 CRAYFISHES. 
A large male, form I., in the U. 8. National Museum, collected in 1897 in 
the Mississippi River at New Orleans, La., measures 53 in. from the tip of the 
rostrum to the end of the telson, the chelipeds are 6% in. long, the chelae 33 in. 
long. The dimensions of a male of about the same size were given on page 23 
of my Revision of the Astacidae. This specimen also came from New Orleans 
(M. C. Z., No. 3,327) and is the same one whose measure was given by Dr. 
Hagen on page 37 of his Monograph of the North American Astacidae with an 
errour of over an inch in the length.

As noted in my Revision of the Astacidae, p. 26, specimens of C. clarkii 
from New Orleans, La., differ slightly from the typical specimens from western 
Texas in having the branchio-cardiac lines in close apposition for a long distance 
through the procarapace, obliterating the areola and reducing the size of the 
anterior and posterior triangular fields. This is well shown in Roetter’s beauti- 
ful drawing of a specimen from New Orleans in Hagen’s Monograph of the North 
American Astacidae, Pl. 4.
