1908] Grinnell.—Biota of the San Bernardino Mountains. 167 
series) 72. There are 8 supralabials on each side, and 10 in- 
fralabials. There are 21 rows of scales around the body, besides 
the series of gastrosteges. Ventrally the snake is pale greenish 
blue, the distal margins of the gastrosteges becoming pinkish. 
The throat, sides of head, and snout, are dull pinkish. Dorsally 
the snake is almost black, more exactly, perhaps, sooty sepia. A 
conspicuous median dorsal straw yellow line runs from the nape 
to the tip of the tail, though on top of the tail it becomes narrow 
and faint. This stripe involves the median scale row, and part 
of the one on either side, especially anteriorly. A small spot of 
yellow marks the top of the head, involving the median margins 
of the two parietal plates. Along each side of the snake its whole 
length and continuous with the lght-colored sides of the head is 
a pale lemon yellow stripe, brightest anteriorly and becoming 
dusky and merging with the ventral color-tract posteriorly. This 
stripe involves the second and part of the third scale rows above 
the gastrosteges on either side. The sides of the head exhibit 
several vertical dusky markings; and the otherwise dark brown 
back is faintly flecked, along either side of the median stripe 
and just above the lateral stripes, with whitish scale edgings. 
There is not a trace of red anywhere. The bright yellow median 
dorsal stripe is a conspicuous feature in the coloration of this 
snake. 
Thamnophis hammondi (Kennicott). California Garter Snake. 
I met with this species only in 1907, when four individuals 
were encountered along the upper Santa Ana. One was taken 
opposite the mouth of Fish creek, 6500 feet altitude, July 9; two 
others were seen near our Cedar Cabin camp, 5500 feet, July 24 
and August 9; and another near ‘‘Lewie’s,’’ two miles above 
Seven Oaks, July 27. All were in or close to the edge of the 
stream. 
So that there may be no doubt to what I here apply the name 
hammondi, 1 will give a deseription of a specimen which it is 
hoped will suffice to identify the species. This description was 
taken directly from a fresh (chloroformed) specimen caught near 
our Cedar Cabin camp August 9, 1907. Its total leneth is 855 
min. (34 inches) ; tail from vent 210 mm. The vastrostezes num-
