natural population of the bisexual whiptail lizard Cnemidophorus tigrls . 

 TRANSPLANTATION 2i*{2): 127-133. 



Abrupt and gradual rejections occurred in a graded sequence in 

 lizards from Utah, suggesting that large numbers of genes and/or alleles 

 are responsible for antigenic properties of skin.

 Cnemidophorus tigris . IMMUNOGENETICS 9(2): 109-118. 



The experiments provided a graded sequence of rejection of skin 

 grafts and indicated that the relative degree of antigenicity of a donor 

 was more or less proportional to its immune response. Probable genetic 

 models for rejection are discussed.

 sidio. IV. Reptiles, birds, and mammals. TEX. 3. SCIENCE 19: 301-310. 



6 different pesticides were found in specimens of Cnemidophorus 

 inornatus , _C. tesselatus and _C. tigris collected within a 30 mile radius 

 of Presidio, Presidio County, Texas. Pesticide concentrations in liz- 

 ards increased from 3une through August. Lizard eggs contained up to 5 

 times the concentration found in the gravid female. 2 more male C^. tes- 

 selatus were collected (3 out of 7 now known come from this area).

Data are given for Cnemidophorus inornatus (10.8 volume %), C. 

 sacki (= sonorae , 11.6 volume %), and C. tigris gracilis (9.6 volume %) 

 from Cochise County, Arizona. Data are related to altitude and active 

 body temperatures, and compared to other lizards and higher vertebrates.
