368 CRAYFISHES. 



A large male, form I., in the U. S. National Museum, collected in 1897 in 

 the Mississippi River at New Orleans, La., measures 5| in. from the tip of the 

 rostrum to the end of the telson, the chelipeds are 61 in. long, the chelae 3| in. 

 long. The dimensions of a male of about the same size were given on page 23 

 of my RcA'ision 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 o\Tr an inch in the length.

As noted in my Revision of the Astacidae, p. 26, specimens of C. clarkii 

 from New Orleans, La., differ sUghtly from the typical specimens from western 

 Texas in having the brancluo-cardiac lines in close appcsition 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, PI. 4.
