182 BULLETIN OF THE 



friend Major LeConte (sec Appendix to McMurtrie's translation of Cuv. 

 An. Kingd., Vol. I, p. 431) was intended for this species, as it is found in 

 the Southern States. We were for several years disposed to regard it as 

 distinct, and have, not without much hesitation, and after an examination 

 of many hundred specimens, been induced to set it down as a variety 

 only." These authors also remark that they are considerably larger in 

 the Carolines than in the Eastern States.*

No specimens of this species were obtained by either Mr. Maynard 

 or myself. Its habitat is usually given as South Carolina and Georgia, 

 but Audubon and Bach man state : " The late Dr. Leitner brought us a 

 specimen obtained in the Everglades of Florida." | It in all probabil- 

 ity occurs also in East Florida. The above-mentioned authors give it as 

 somewhat common in the salt-marshes near Savannah and Charleston. 

 Professor Baird has received it from Columbus and St. Simon's Island, 

 Georgia, and Society Hill, South Carolina.

I found this species very abundant on the Lower St. John's, espe- 

 cially around Jacksonville and Hihernia, but I did not meet with it 

 above Lake George. The old residents about Ilawkinsville seemed 

 •wholly unacquainted with it. Mr. Maynard also failed to meet with it 

 on Indian River. It hence appears probable that it may not occur 

 very frequently in the southern part of the peninsula. Professor Baird, 

 however, lias recorded a specimen from "Indian River, Fla.," collected 

 by Dr. Wurdemann. 



The present usual northward range of this species does not appear 

 to extend beyond North Carolina ; but Professor Baird, writing in 1837, X
