mottled with j^ray and dusky. Gular regions paler yel- 

 lowish-white, mixed with dark gray; the larger scales 

 with bright yellow tips. 



Length, 142 mm.; head, 21 mm,; hind leg, 60 mm.; 

 fore leg, 45 mm.; tail, 52 mm. 



Habitat: Santa Clara, Santa Cruz, Monterey and San 

 Benito counties, and near Lemoore, Kings County, Cal- 

 ifornia. 



There is great individual variation in the color of the 

 specimens before me. This is perhaps explained, at 

 least in part, by the fact that a live specimen changed its 

 colors considerably in the course of a very few minutes. 

 This was particularly well marked upon the chest and 

 belly, which changed, in about three minutes, from a 

 bright yellow with numerous slate colored spots, to a yel- 

 low of a slightly lighter hue from which the black spots 

 had entirely disappeared. 



Uta microscutata sp. nov. 



Two specimens of Uta from Lower California, while 

 manifestly related to U. nigricauda, as shown by the 

 presence of a single frontal, the general style of the dor- 

 sal lepidosis, and the coloration, differ so much from that 

 species (by the small size of the dorsal scales, the very 

 gradual change from the largest dorsal scales to the 

 granular laterals, the blue instead of orange gular patch 

 in the male) as to make their separation imperative. 



Description: Adult male (Type, No. 1221, Leland 

 Stanford Junior University Museum, collected by J. M. 

 Stowell, in the San Pedro Martir Mts., Lower California, 

 June 20 or 21, 1893). A single frontal; four large supra- 

 oculars ; one large and two small projecting scales on the 

 anterior border of the ear. The largest dorsal scales are 

 along the median line, on each side of which they be- 

 come gradually smaller, until a granular form is assumed
