"Silvery (in spirits); upper part with very narrow brown zigzag lines
placed on the margin of the series of scales, the line down the center
of the back and two or three on the upper part of the sides being
thicker and nearly half the width of the scales.
_Hab._ California, _J. O. Goodridge, Esq., Surgeon R. N._"
This species has since been more completely described by Bocourt,[11]
Boulenger,[12] Cope,[13] and Van Denburgh.[14]

In 1885 Fischer[15] described under the name _Anniella nigra_ a
specimen said to have been collected at San Diego, California.
This, he stated, differed from _Anniella pulchra_ in the following
characters:
1. Twenty-eight longitudinal rows of scales.
2. The three median preanal scales twice as long as those
preceding.
3. Tail one-third total length.
4. Color above black.
[Footnote 15: Abh. Nat. Verein Hamburg, v. 9, Hft. 1, 1885, p. 9.]
I have elsewhere[16] stated that the number of scale rows in _Anniella
pulchra_ varies from twenty-four to thirty-four. The preanal scales
in both the dark and light forms may be small, moderately enlarged,
or twice the length of those preceding. The tail of _A. pulchra_
may equal or exceed one-third of the total length of the animal. I
have been unable to discover any differences in the squamation of
dark and light specimens; and since the recognition of _A. nigra_ as
distinct from _A. pulchra_ must rest solely upon the difference in
pigmentation, one is tempted to inquire whether this is not merely an
instance of melanism. Upon this subject I shall have more to say, but
I wish first to consider certain peculiarities of squamation which
have been held to distinguish another species.

_Anniella texana_ was described by Mr. Boulenger,[17] in 1887, from
a single specimen labeled El Paso, Texas--a locality so far beyond
the limits of the known range of the genus and of other Californian
reptiles that it must be regarded with much suspicion until confirmed
by the capture of additional specimens. The type of _A. texana_
agrees in coloration with _Anniella pulchra_, but Mr. Boulenger finds
it to differ in certain details of squamation. He assigns to it the
following characters:
1. Head less depressed, snout more rounded than in _A. pulchra_.
2. A horizontal suture from nostril to second labial.
3. Frontal twice as broad as long.
4. Anterior supraocular nearly as broad as its distance from its
fellow.
5. Interparietal and occipital divided (anomalously?) by a
longitudinal suture.
6. Six upper labials, etc.
