band uniform in color, darker than upper bordering 
stripes, lighter than lateral bands. 
Seventeen Kansas specimens of this species have been . 
measured, and the data are as follows: Length of body, 
23-61; length of tail, 38-96; total length, 70-146; width 
of head, 4-9; length of tail as percentage of total length, 
47.0-65.8; width of head as percentage of body length, 
13.1-16.0. 
A longer specimen than any designated in the above 
summary was examined by Hurter (1911), who gave the 
total length of the coal skink as 157 mm., tail 101 mm., 
and body 56 mm. 
A Kansas lizard, collected by Mr. Jack Sterling at 
Carlton, Dickinson County, Kansas, has been recently 
identified by the United States National Museum as EL. 
pluvialis. Dr. L. Stejneger and Miss Doris M. Cochran 
have compared this specimen with the co-type of E. 
anthracmus and find that the former has long toes, and 
delicate, slender limbs, in contrast to the short toes, and 
heavy, thick limbs of the co-type of E. anthracinus. 
A detailed study of the variation presented by speci- 
mens of E. anthracinus* from various points throughout 
its range, and also related work with other species of 
lizards, has clearly indicated to the writer that the length 
of both the legs and toes is a highly variable characteris- 
tic, which, though of considerable importance in deter- 
mining affinities, is usually not of primary significance in 
the identification of closely related species. Therefore, it 
appears that EH. pluvialis may be a synonym of E. an- 
thracinus, and consequently, all Kansas specimens of this 
section of Eumeces will be discussed here under the head 
of E. anthracinus. 
*The writer intends to present these data, and also a discussion of 
the relationship between E. anthracinus and E. pluvialis in a forth- 
coming paper.
