Of Sceloporus graciosus graciosus there are in the Museum of Verte- 
brate Zoology 282 specimens, from Mount Pinos, Ventura County, the 
southern Sierra Nevada, central and northern California, Humboldt 
County, Nevada, and Wallula, Washington. 
Remarlis—The series of sixty-three vandenburgianus from the San 
Gabriel and San Bernardino mountains is nearer graciosus in colora- 
tion than specimens from farther southeast. Several large males (nos. 
776, 777, 781, 783, 790) from the San Bernardino Mountains eannot 
be told from typical vandenburgianus, and some others are lighter ven- 
trally than any males from south of San Gorgonio Pass. The series 
from the San Gabriel Mountains includes the lightest-colored males 
of the subspecies, and they are in this respeet very good intermediates, 
despite their isolated station, between the small, hght-colored graciosus 
of Mount Pinos and the large, dark blue specimens of vandenburgianus 
from the headwaters of the Santa Ana River, and farther south. 
Cases of this sort of distribution bear on the question whether 
intermediates between two adjacent forms may be hybrids. In the 
present instance the low passes of Soledad, Cajon and San Gorgonio 
separate the range of the intermediates into a chain of mountain-top 
‘islands’? and seem to preclude the possibility of hybridization at the 
present time. 
The darker ventral color and larger size of the southern race of 
this species is interestingly paralleled in Sceloporus occidentalis, Ger- 
rhonotus scincicauda, Cnemidophorus tigris, and Eumeces skillonianus, 
in which species the southern and desert forms are bluer or blacker 
beneath and duskier above. 
Novres on UTA STANSBURIANA 
Richardson (1915, pp. 412-418) separates Uta stansburiana into 
the following three subspecies: U. s. stansburiana, characterized by 
its greater number (average 103.4) of dorsal rows of weakly carinated 
seales and its few femoral pores (average 13 +); U. s. elegans, with 
from 78 to 103 (average 86) dorsal rows of more heavily keeled scales, 
an average of 14-+ femoral pores and a greater tail length; and U. s. 
hesperis, with from 87 to 117 dorsal rows of heavily carinated scales, 
and an average of 14+ femoral pores. He extends the range of the 
typical subspecies, sfansburiana, into California on the basis of two 
specimens from Round Valley and Lone Pine, Inyo County. Counts
