1()6() REPORT OF NATIONAL MUSEUM, 1898. 



Superior row ot" dorsiil spots confluent into a longituiliual band in contact with 

 the inferior row of spots, which are separated l)y red interspaces; lateral spots 

 from SO to 90 ; no gastrostegal spots E. s. parteiaViH 



Lilie the last, but the inferior spots connected by a black band inclosing tlie red 



spots; throat and lii^s red; belly bhick; spots from 64 to 82 E.a.concinna 



IV. Hands, but no sjjots. 



Three longitudinal lines on the middles of the second and median rows of scales, 

 mostly blue ; belly black E. 8. inckeringii 



Three well-defined bluish bands of usual width; belly black U. s. trtlineata 



A yellow dorsal band; the lateral loss distinct; belly green and with gastro- 

 stegal spots E. s. ohscura 



On each side a red stripe between two of black E. .s. tetratwnla. 



These subspecies are distributed as follows : 



Transitions between these forms aie common. The disappearance of 

 the spots and stripes of E. s. sirtalis, which culminates in the IJ. s. 

 yraminea, does not occur abruptly, but transitional specimens are not dif- 

 ficult to find. Transitions to the dark form, U. s. ohscura, are not rare, 

 the spots becoming, as in the correspouding case in U. elegans, confused 

 and blended on the posterior part of the body first. The transition to 

 the absence of spots also appears first posteriorly, Cat. No. 7798 having 

 anteriorly the color marking of E. e. parietalis, and j)osteriorly that of 

 E. e. dorsalis. On the other hand, the E. e. parietalis shows every 

 gradation to the form E. e. ohscura, by confiuence of the spots. The 

 spots are largest and fewest in E. s. sirtalis, where they range from 

 seventy-six to seventy-eight. In E. s. parietalis they are more numerous, 

 ranging from eighty-three to eighty-eight. E. s. dorsalis covers botii 

 series, ranging from seventy to eighty-one.
