Males bronzy, olive, or dark green above, uniform or with yel- 

 lowish or pale greenish spots, which may be confluent into cross- 

 bars ; usually a broad black nuchal collar edged with yellow or 

 pale green behind or both in front and behind ; this collar is some- 

 times interrupted on the back, or reduced to an oblique black band 

 on the shoulder. There is every passage between specimens with 

 and without the collar. Throat and sides of belly cobalt-blue ; 

 breast and middle of belly and groin black or white, or black with 

 some white spots ; groin black. 



Females often more brownish above and yellowish-white beneath, 

 uniform or the throat marked with olive and the sides greenish. 

 In some specimens (Omilteme) the throat and the sides of the 

 belly blue. 



The variations of this species, both in scaling and coloration, have 

 given rise to a number of nominal species and subspecies, which I 

 feel unable to accept. 



The best-defined form is the 8. poinsettii of Baird and Girard, 

 in which the supraoculars, often also the frontal, are broken up 

 and the femoral pores fewer (9-15) than is usually the case in the 

 typical S. torquatus. But, following Bocourt and Cope, I can only 

 regard it as a variety or subspecies of S. torquahis, because speci- 

 mens occur showing an intermediate form of supraoculars, such as 

 are tabulated in division B of my hst, and because I find similar 

 variations occur in S. spinosus ; and as the number of femoral pores 

 varies in the typical form from 14 to 20 the second character also 

 is not in all cases a distinctive one. Giinther accepts ;S'. poinsettii 

 as a distinct species, overlooking the intermediate specimens with 

 regard to the supraoculars, and stating the number of femoral pores 

 to be 11 or 12 in S. ])oinsettii and 15 to 20 m 8. torquatus, not- 

 withstanding that he had access to specimens of the former (from 

 Texas) with as many as 14 pores. The character derived from the 

 coloration he himself admits to pertain only to the specimens from
