to clove brown. Scattered granules are dark brown or 

 black. At times these dark granules are so numerous 

 as to become confluent, with a tendency to form longi- 

 tudinal lines. In other individuals they are scarcely 

 visible. Some specimens have heavy dotting on a very 

 pale ground; in others the dotting is heavy on a dark 

 ground; many show faint dots on a light ground; and 

 several have few dots on a dark ground. A yellowish 

 line usually runs back on the neck from the outer edge 

 of each occipital plate. Two similar lines may some- 

 times be seen above these. The lower parts are creamy 

 white, sometimes clouded with brown toward the sides. 

 The young average much darker than the adults.

Distribution. — The Desert Night Lizard is the most 

 abundant of its class in the territory it has chosen for 

 its home. It seems to be peculiarly dependent upon 

 the presence of tree yuccas. These weird plants grow 

 in each of the localities from which the lizard has been 

 recorded, viz.: Fort Tejon in the Canada de las Uvas, 

 Kern County, and Hesperia, San Bernardino County, 

 California, and Pahrump Valley, Nevada. 



Dr. Charles H. Gilbert and the writer collected speci- 

 mens near Mojave, Kern County, and found a portion 

 of a cast skin at Victor, San Bernardino County, in 

 November, 1893. In September of the following year,
