 real rows; fourteen supraorbital rows; hind foot longer,

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-

 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. 



Callisaurus BLAINV., Nonv. Ann. Mns., IV, 1835, p. 286 (type 

 draconoides); Megadactylus FITZINGEB, 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
