The swollen medial gulars grading pos- teriorly into swollen gulars less than half their size. Trunk (Figs. 4 and 5): The middorsal scales, a dorsal crest of Type 3 sensu Lazell (1969, fig. 1), a single series of vertebral scales, swollen keeled cones, at irregular intervals each such scale sep- arated from other vertebrals by a pair of flat or slightly swollen paravertebrals that meet middorsally. In the male the sequence of the 2 types of middorsals is nearly regular until the region of the sacrum, where the cones are in contact. About 4-5 rows of paravertebrals, rounded and flat, varying somewhat in size, in contact or slightly overlapping and showing little or no intervening skin. Below this on each flank a zone of distinct granules, mostly fully separating round flat scales that difler little from the par- avertebrals in size but tend to be somewhat smaller. Below this, beginning at about the middle of the flank patches of slightly larger round flat scales in partial contact appear; they appear to be concentrated in irregular areas that are more lightly pigmented than the rest of the flank. Ventrals smooth and strongly imbricate,.
