would not continue singing when the observer turned 
the light on them or approached nearer than fifteen 
or twenty feet, and so could not be located. A silent 
andersonii in a thick tangle of Blueberry bushes could 
give points on hiding to a very small needle in a very 
large haystack. No females were taken. 
The writer would not have presented this evidence 
regarding andersonii at such length except that in 
some degree it contradicts statements previously made 
in the literature regarding the species. 
It is to be expected, of course, that individuals will 
always differ in different localities. It is only by taking 
the sum total of observations from a great many 
localities, and averaging it, that we dare generalize 
about a species, and even then we cannot do it with 
perfect safety. 
All specimens taken have been placed in the collec- 
tion of Cornell University, except the andersonii 
which were unfortunately lost after arrival in Ithaca.

ON SOME SKINKS OF THE GENUS EUMECES 
FROM NORTH AMERICA 
Recently, when attempting to identify a skink 
(M.C.Z. 28383) collected by Prof. C. T. Brues on 
Los Coronados Islands, I observed that it combined 
the key characters for Eumeces skiltonianus and E. 
lagunensis. Van Denburgh ("Reptiles of Western 
North America," 1922, Vol. I, p. 578) defines them as 
follows: 
b. Interparietal larger than a frontoparietal, 
separating parietals; tail of young usually 
blue ......................... P. skiltonianus 
b2. Interparietal smaller than either fronto- 
parietal, not  separating  parietals;  tail 
salmon-color ................... P. lagunensis
