tinguished by one or two prteoculars and by one loreal only, as inravergieri. The table conclusively proves the specific identity of all the specimens thatappear in it, but at the same time establishes the desirability of regarding the westernsnakes as constituting a variety distinguished by slight modifications of no greatstability. The number of the upper labials entering the orbit—i. e. whether they are the 5th,5th & 6th, and so on—when the normal number 9 is present, depends chiefly on thecircumstance whether a portion is separated off from the sixth labial or not; and whentheir number is increased or diminished, the number to be assigned to them depends, ofcourse, on whether the increase is due to division of the labials before or behind theorbit, and the same holds good of reduction in the number 9 by amalgamation. Theremay also be union of the postoculars or division, and with these facts kept in viewthe variations recorded in the foregoing tables are easily explicable.
