. Sistrurus catenatus catenatus (Raf.). 
Described by De Kay as extra-limital, but added by Gebhard (Sixth 
Annual Report on Condition of State Cabinet, Albany, p. 22, 1853), 
as specimens had been sent in from Genesee County. There appears- 
to be no recent definite record of their occurrence in that region.

A 
. Crotalus horridus (Linn.). 
Still occurs in Orange and Rockland Counties, but very rare and 
possibly extinct east of the Hudson in this state. Cope notes a speci- 
men collected in 1878 at Katonah, Westchester County ; and I have 
been informed that one was killed in 1887 near White Plains.
