The characters of the three suborders of the Squamata are then as 
follows: 
Quadrate bone articulating with exoccipital; paroccipital external to 
bones of brain case ; parietal bones not closing the brain case in front ; 
generally an epipterygoid and sternum; teeth with dentinal roots; 
phalanges with condyles ; Lacertilia. 
Quadrate bone articulating with paroccipital, which is embraced by 
bones of brain case; parietal bones not closing brain case in front ; 
epipterygoid and sternum present ; teeth with osseous roots; phalanges 
truncate ; honomorpha. 
Quadrate bone articulating with paroccipital ; parietal and frontal 
bones closing brain case in front; no epipterygoid or sternum; teeth 
rootless; no phalanges ; hidia, 
I cannot agree with Boulenger that the Chameleontide represent a 
division of equal rank with these three, as most of the characters may 
be found in one Lacertilian or another, and the group isin many ways 
related to the Agamide of the Pachygloss division. For me it repre- 
sents a superfamily for which the name Rhiptoglossa is available.—E.

dotted surfaces represent the articular surface for the quadrate. 
A New Xantusia.—A specimen sent me by Dr. J. J. Rivers of 
Berkeley, Cal., taken at Tejon Pass California, indicates a new and 
handsome species of Xantusia. It is allied to the Zablepsis henshavii 
of Stjeneger (see last number of the Naturauist where the genera of 
Xantusiidae are defined), but differs in generic characters. It has longer 
limbs and a longer tail than in either of the Xantusie known. The 
hind leg extended forwards, reaches the shoulder, and the tail is twice 
the length of the body. There is but one row of superciliary scales, 
and there is but one frontoparietal on each side. Seven superior 
labials, not separated by scales from orbit. Four inferior labials, the 
fourth separated from the third by the large third infralabial, which 
reaches the lip border. Fourteen to sixteen longitudinal rows on the 
belly. Ten femoral pores. Color above light reddish-brown, marked
