REPTILES OF THE PACIFIC COAST, 47 



6. — Uma notata Baird. Sand Lizard. 



Umanotata, Baird, Proc. Acad. Nat. Sci. Phila., 1858, p. 253 (type 

 locality Mojave Desert); Cope, Am. Nat., 1895, p. 939. 



Description. — "Labial scales weakly keeled; nine lo- 

 real rows; fourteen supraorbital rows; hind foot longer, 

 two-fifths head and body; femoral pores nineteen. 

 Black spots on side of belly but no crescents on throat." 

 " Head about two-fifths the head and body. Above light 

 pea green, spotted with darker green. Beneath white."" 



Distribution. — Mojave Desert. 



Habits. — Unknown . 



7. — Uma inornata Cope. Plain Sand Lizard. 



Uma inornata Cope, Am. Nat. 1895, p. 939 (type locality Colorado 

 Desert, San Diego Co., Cal.). 



Description. — " Labial scales strongly keeled; five or 

 six loreal rows; ten or eleven supraocular rows; hind- 

 foot shorter, one-third head and body; femoral pores- 

 nineteen. No black spots on belly or crescents on 

 throat." 



I do not feel certain that these two supposed species- 

 are really distinct. The slight differential characters 

 which have been pointed out are manifestly rather vari- 

 able, and each name is based upon a single specimen,, 

 at least one of which (U. notata) is young and in a very 

 poor state of preservation. 



Distribution. — " Colorado Desert, San Diego County,. 

 California." 



Genus 7. CALLISAURUS. 



Callhaurus Blainv., Nouv. Ann. Mus., IV, 1835, p. 286 (type 

 draconoides); Megadactylus Fitzinger, Syst. Kept., 1843, p. 59 

 (type draconoides); Homalosaurus Hallow., Proc. Ac. Nat. 

 Sci. Phila., 1852, p. 179 (type ventralis). 



The lizards of this genus have the body and tail con- 

 siderably flattened, legs very long, and the head rounded
