VIVIPARA. 19 
”? 
I recognize Vivipara viridis, Hanley, 
because I am acquainted with the spe- 
ndif I did not know it by specimen, 
or description, the name would not aid 
ull in identifying it, for ald Viviparas are 
and fifty species are as green as viridis 
2 of them more so. It will suit my pur- 
ually well whether the species be named 
us, rufus, grandis or parvus, so it has a 
and one which, being founded on the 
principle of absolute priority, without 
am or any other limitation, shall not be 
:d for any fancied improvement.* 
unted out in the Proceedings of the 
elphia Academy of Natural Sciences for 
he fact that four-banded species were 
American, and those with three bands 
san, that one species only has two bands 
‘ermondiana, D’Orb., of Cuba,—and that 
se are distinguished from the Asiatic 
by color, the bands in the former being 
Haldeman’s very just remarks on specific nomen-
