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. Pemales 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 S. polnsettll 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. torquatus, because specimens occur showing an intermediate form of supraoculars, such as are tabulated in division B of m y list, 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. polnsettli 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. polnsettll and 15 to 20 in S. torquatus, notwithstanding 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 |
