Comment: Nelll and Allen, Publ. Res. Div. Ross Allen's Rept. Inst., 2, 1555, *7> suggested 

 that this should be .cons idered a subspecies of annulatus . Smith, in Smith and Taylor, 

 Herpetology of Mexico, Preface, I566, 26, indicated that it perhaps should be a junior 

 synonym of annulatus . Stuart, Misc. Publ. Mus. Zool. Univ. Mich., 122, l')(>J, IH, 

 recognized this as a full species. We do not know what the status of this taxon really is.
