but the whitish ventral plates usually are conspicuously 
marked at their bases with black or dark brown. 
The young of this subspecies are not distinguishable from 
those of LZ. g. dboyliz. All the larger individuals agree in 
having the scales of the white rings marked basally with 
black or dark brown. This black edging seems to appear 
first upon those scales which are nearest the median dorsal 
line, and to extend to the lateral ones and over more and 
more of the surface of each scale as the snake increases in 
size.

Remarks.—This snake is so similar in appearance to 
L. g. yumensis that I regarded them as identical. According 
to Blanchard, however, this resemblance is only apparent, 
and these two subspecies need never be confused. He states 
that they are not even related directly. L. g. conjuncta 
shows closer affinities with Joylii than with yuwmensis, “an 
the pattern and scalation of the head, and in the fact that 
its young are indistinguishable in the coloration of the white 
rings from the young and adults of doylii; and that the basal 
shading of the white scales, which has resulted in the con- 
. fusion of the southern Arizona specimens with those from the 
Cape Region, may well have been derived by conjuncta 
directly from doylii, since the latter shows this character 
sporadically throughout its range.” 
Distribution —The known range of this subspecies, as 
restricted by Dr. Blanchard, is confined to the Cape Region 
of Lower California. The type was taken by John Xantus 
near Cape San Lucas. Mr. Belding found this snake at La 
Paz. I have seen specimens from San José del Cabo. It has 
been taken also at Santa Anita.
