ZOOLOGY. 
active animal, and lias a greater expansion of the thin membrane of its tail than during its 
terrestrial life. 
The spawn mentioned as deposited by this species in the water may have belonged to some 
other animal, as most salamanders are believed to deposit it on land, under stones, &c .; but I 
never found any in such situations. 
Note.— Both Mr. Gibbs and myself found near Steilacoom a small kind of salamander under 
logs and stones, which seems to be undescribed. The specimens were, in some way, lost or 
destroyed. When alive, they were pale purplish, with yellow longitudinal stripes.—C. 
Among the lost collections from the Dalles was a small salamander, found in January, 1855, 
which had the sides deep blue, with light markings; belly spotted with black. No such 
species is known to naturalists.—S. 
SIREDON LICHENOIDES,? Baird. 
“Ground Puppy;” “Four-legged Fish.” 
Siredon lichenoides ,? Baird, Stansb. Salt Lake Exp. 1852, p. 336, pi. 1. 
A specimen of siredon collected by Dr. Suckley, near Fort Union, Nebraska, differs from the 
typical S. lichenoides, in fuller form, and in the presence of distinct rounded black spots on a 
grayish brown ground, the spots larger and more distinct than in S. mexicanus; the eyes are 
more anterior. In the absence of tangible, distinctive characters, it is difficult to say if this 
animal be really distinct from lichenoides • but it may, at any rate, be considered as a well 
marked variety, S. melanosticta. The total length of the specimen, No. 4073, is about nine 
inches.— Baird. 
This siredon was obtained on the route between Fort Union and Fort Benton, Nebraska. 
"Vast numbers of a species apparently identical are found in the small brackish lakes of central 
Minnesota, where I procured some thirty or forty specimens, which were, unfortunately, 
afterwards lost on their way to Washington city. The species is, apparently, permanently 
aquatic; the only occasion upon which I noticed them out of their native ponds was when, 
during a terrific thunder shower, I found many in the wet grass within a few feet of a small 
prairie lake, to which they had retreated from the water, apparently from fright produced by 
the loud claps of thunder. I generally obtained them by dragging a seine through the small, 
shallow, muddy ponds, so numerous in that region. The contents of my net were generally 
confined to those animals, and vast numbers of aquatic insects.—S.
