ZOOLOGY. 309 
the salmon and salmon trout have bred in the Plenty ponds, in 
fresh water, without ever having a chance of emigrating to the sea. 
Frank Buckland proposes to send out a uet, wherewith to test 
the presence of salmon, from which we may infer that such an 
obvious means of ascertaining the facts has not yet been tried, al- 
though there was ocular proof of the presence of great numbers of 
fish supposed to belong to the two species in question. The eggs 
from which the Salmonide now in Tasmania, are descended, were 
sent out packed in ice. A large case of salmoneggs was shipped 
for New Zealand, last November, packed without ice, in glass jars 
with damp moss. — C. G. A. 
Curious Hanrrs or a Swaxe. I had for some time living in a 
Wardian case, a specimen of Oyclophis estivus, received from Ft. 
Macon, N, C., through the kindness of Dr. Yarrow. The slender 
form of this snake, and its beautiful green and yellow coors have 
led to the opinion that it is of arboreal or bush-loving habits. It 
never exhibited such in confinement, however, and instead of 
climbing over the ferns, etc., lived mostly underground. It had 
an envious habit of projecting its head and two or three inches 
of its body above the ground, and holding itself for hours rigidly 
in a single attitude. In this position it resembled very closely 
à sprout or shoot of some green succulent plant, and might readily 
be mistaken for such by small animals. — Epw. D. Corer.
