With Plates xLI-xiviit and 15 figures in the text. 
Tue four papers of this series are intended to include the results 
of a general study of some of the principal organ systems of a 
rather common but yet little known lizard, Anniella pulchra, found 
on the barren sand dunes of California, Arizona, and southward. 
This form presents a number of anatomical features which deviate 
more or less widely from those usually thought to be characteristic 
of the lizards. in some respects these structures are quite different 
from those which have thus far been described for any other form. 
The reproductive organs exhibit a feature apparently quite unique 
among lizards in that but a single oviduct is functional, the other 
being aborted and quite incapable of carrying an embryo. The 
copulatory organs likewise show a number of interesting deviations 
from the ordinary lacertilian type. An abstract of a paper dealing 
with the peculiarities of the urogenital and copulatory organs has 
been published in the American Naturalist (Coe and Kunkel, : 04). 
A second paper on the female urogenital organs of this form has 
appeared in the Anatomischer Anzeiger (Coe and Kunkel, :05). A 
detailed and more fully illustrated account of these structures con- 
stitutes the third paper of this series. 
A general account of the habits and mode of life both in the 
natural habitat aud when in captivity, together with a brief discus- 
sion of the visceral anatomy, is included in the first of the four 
papers of this series, 
The external anatomy and skeleton have already been briefly 
described in the papers by Cope (’92 and :00) and by Baur (’94) 
and the systematic position of the genus discussed. Further details, 
however, both in regard to the arrangement of scales and the 
osteological peculiarities, are described in the second paper of this 
series. 
The central nervous system and particularly the parts of the brain 
associated with the pineal apparatus have been carefully investigated 
and constitute the subject of the last paper of the series. 
These structures by no means include all the anatomical peculiari- 
ties of the genus, for as yet no studies have been made on the circu-
