In the Museum of Comparative Zoology there is a specimen of C. Bar- 

 Innii (Cat. No. 3358) labelled " Charleston, S. C. ? " and three specimens (No. 

 1101) in the same jar with an Alpheus are marked "Pico, Azores, Miss 0. 

 Dabney, May 23, 1860." The latter locality, at any rate, is probably erro- 

 neous. Hagen states (p. 77) that he has seen a specimen from Georgia ; and 

 I find in the collection of the Boston Society of Natural History this species 

 in the same bottle with a Pagurus and Hyas coarcfatits, labelled " Savannah, 

 Ga., Dr. H. Bryant." The presence of the marine forms, especially the 

 Northern Hyas, casts doubt on the correctness of the label. The locality 

 label, " Osage River," is marked by Dr. Hagen as being very doubtful.
