the (jidailx <j.roii|)."' Since s[)ecinieiis ot" the (/iilnris oi(>ii[) (of 

 GadoAv) do not oceiir in California, and because of Van Denhurairs 

 statement, septcint'itfdfnx has of hite been "deprived" of h)cality. 

 Wriirht and Funkhouser (1015, p. 13-i) wrote that '* it mi<j:ht be noted 

 that in many of the s[)eoimens reported from tlie Okefinokee the 

 phite arrangement a<^rees nuich more nearly Avith tlie descri])tion 

 and figure of septemvittatus than ^ith sexJ meatus. * * * In 

 fact, if the median dorsal lonfritudinal line Avhich sometimes appeals 

 were more distinct, some of these specimens would seem to merge 

 into typical septemmttatus.''^ Contrary to this suggestion, an ex- 

 amination of the type shows that it is typical pcrpJcxus^ for the vspeci- 

 men is partly lined, i)artly spotted, and partly cross-barred. The 

 field spots are irregularly placed and appear to be spreading or 

 becoming dominant over much of the ground color to produce a more 

 or less definite '" scalaris "' type of coloration. Because of a peculiar 

 intensification of the ground color to a deep black, the color pattern 

 of the t3'pe of septemvittatus is rather distinctive. A comparison of 

 the type with a specimen from jNIarfa, Tex. (U.S.N.M. Xo. 33073), 

 shoAved the two to be identical in coloration and in other respects, 

 and subsequently the ]Marfa specimen has been compared with a 

 large series of specimens from Brewster County. Tex. (Mich.), and 

 these have also been found to represent the darker phase of perplexus. 

 Therefore, the tj'pe of septemvittatus may be assumed to luive come 

 from this general locality. All of these specimens are alike in 

 having enlarged postantebrachials, so that theie is little need to 

 confuse them with tessellatus, which, in the higlier levels, sometimes 

 has a very similar general appeai'ance, but fortunately, has only 

 granules on the posterior surface of the forearm. The absence of a 

 dark ventral suffusion and of a yellowish middorsal streak alters 

 septemvittatus to 2)G''ple,i'Us rather than to rjulavis, and the appear- 

 ance of typical 6 to 7 lined young in the same habitat (Brewster 

 County, Tex.), further supports this vicAV. The peculiar dark 

 ground color occurs only in upland specimens as in tessellatus (see 

 account of this under that form, pp. 154-157 and 166), and is not 

 wholly constant, so septemvittatus is not given recognition here as 

 a distinct entity. 



In 1892 Cope described scaJaris from a series of specimens from 

 Southern Chihuahua which have been found to be intergrades be- 

 tween cjularis and perplexus. These are discussed under gularis. 

 Scal,aris represents the end evolution of the color pattern of both 

 forms and it was logical for Van Denburgh (1S96, p. 343) to write 

 as follows about two specimens from Arizona : '* These agree very 

 Avell with the original description. They are much larger than 

 gularis, and are possibly, though imiM-ol)ably, very old males of that 

 species." The futility of recognizing the two forms as distinct was
