In general appeaniiice, size, and proportions, as w(dl as in pattern and tints of coloration, except in their details, there is a wonderfully close resem- blance in this race of S. nnin to the X sniiHori/ncs, Sehlegel, of Japan. In- deed, it is ])robable that the latter is also a mere gco2;rai)hical form of the .same species. The only tan,uil)le ]ioiiits of difference are that in .frinitorquci the juguluni is distinctly white centrally, there is a quite well-defined lighter nnelial band, with a more indistinct occipital one above it, and the iiencil- on the lower parts are more delicate. Tlu; size and proportions are the same; the shades of color arc identical, while the markings differ only in minute detail, their pattern being the same. In kcnnicofti the light nuchal collars are indicated, Ihoiigli they do not approach the distinctness .shown by them in scmitoi-qiws. Should they be considered.
