ZOOLOGY. 
Sp. Ch. — Body long and slender ; head short, broad, and high, thicker than neck. Dorsal rows 20 or 21 ; stripes faint or 
partly wanting, with two rows of brown or black spots, about one hundred in number, on each side, confluent with the 
stripes. Scales of tail and outer dorsal row distinctly carinated. Labials, 8 above, the sixth and seventhjlargest, higher than 
wide. Ground color above light olive brown, the stripes paler ; beneath, slate color. 
Found in the Yakima valley in August, but is known to extend also west of the Cascade 
range. — C, 
Found at Puget Sound and at Fort Boise, on Snake river. While on Boise river I saw a snake 
apparently of this species, which, upon being pursued, retreated to a small hole in the ground, 
the calibre of which was just sufficient to admit its occupant. Whether the hole had been 
excavated by the serpent, or was simply the burrow of some small rodent, I had no means of 
ascertaining. — S.

Sp. Ch. — Body moderately lengthened. Head small. Dorsal rows, 21, carinated. Vertebral stripes yellow; wo lateral 
Stripes, but in their place a series of 75 salmon red spots or bars extending from the second to sixth rows of scales, and 
covering from half to two scales width. Ground color black, belly slate or greenish black, whitish anteriorly. Head reddish 
yellow, tinged witli brown. 
Found at Vancouver, and not observed along the coast. — S. 
Were it not for the distinction in the scales of the liead and back, which in this genus are 
relied upon as specific characters, and even decide the species into gi'oups, these five species 
might be combined into two by their colors. E. cooperii, le-ptocephala, and vagrans, approach 
each other very closely, and pickermgii, especially the variety with one stripe, much resembles 
condnna ; in fact, some specimens have much the appearance of being hybrids. More obser- 
vations and specimens will be required to decide what characters are truly specific. 
All these garter snakes have very similar habits, and are equally harmless. It is generally 
believed that those with carinated scales, like the three last species, are more aquatic in their 
habits, and I did notice this to be the case with vagrans and leptocephala; but all of them live 
not far from water, and in the dry season, at least, are found almost always near it. Another 
favorite resort is the Indian burying-grounds, where the corpses, placed above ground, attract 
numerous insects; and it is these, not human flesh, which forms the food of the beautiful little 
garter snakes, notwithstanding the association of graves and serpents so common in the minds 
of poets and people. 
The Indians have something of the same natural (?) horror of even harmless snakes that per- 
vades more civilized races; and it is due to the same ignorance, for they have frequently told 
me that snakes were poisonous which I handled with perfect impunity. Perhaps, also, super- 
stition is connected with this antipathy. — C. 
EUTAINIA HAYDENII, K e n n i c o 1 1 . N. S. 
Plate XIV. 
Sp. Ch. — Head broader and more depressed in front than in F. radix. Form stout, compact, and cylindrical, most so of 
the genus, except E. radix. Ground color light olive green, with three longitudinal yellow stripes, and six sei-ies of distinct 
black spots. In life some red coloring visible on the sides. Lateral stripe on the third and fourth rows less sharply defined 
than in E. radix. Dorsal rows, 21. — Kennicott.
