REPORT OF NATIONAL MUSEUM, 1898. 



The tail measures into the total length as follows : Cat. ISTo. 844 (type), 

 four and one-tenth times; Cat. No. 7235, four and tliree-iifths; Cat. ^o. 

 404, four; Cat. No. 5351, four; Cat. No. 841G, four and two-fifths; Cat. 

 No. 1418, four and one-fourth. 



As in IJ. e. ra(jrans, the top of the head is black in young specimens. 

 In very large specimens an approximation to the E. e. vagrans is seen 

 the paling of the dorsal spots by the restriction of the black color to 

 the skin and its disappearance from tlie scales. The spots below the 

 lateral lines become especially indistinct, and this is important, since 

 these are one of the distinguishing features of the species (Cat. Nos. 

 841G, 8117). The head markings retain their bright contrast of colors, 

 so that the subspecies is always easily distinguished. 



The range of this species is rather restricted, being c(m fined to the 

 Rio (Irande Valley and a limited region on each side of it to its mouth. 

 In Texas it extends as far east as San Antonio.

This form is quite different from anj^ of those enumerated as sub- 

 species of E. elegans, but it resembles considerably the E. sirtalis 

 jHirietalis. The distribution of colors is quite the same as in that form, 

 but the red between the lateral spots is of a chestnut color, and not
