Ten or more supraorbital scuta; plates of muzzle flat; labials exceedingly narrow, live in number, followed by a flat one. Femoral pores 16-18. A pair of blue spots on the side; none under the tail. This species, in addition to the general characters of the type H. maculata, diflers in the excessive minuteness of the dorsal scales, which can scarcely be counted, even with a good lens. The head is more elongated and quite plane from above the end of the eye, instead of slightly convex. Its width reaches only from the end of snout to mid- dle of occipital, instead of behind it. There are seven oblique upper labials instead of six. The legs are all much longer; thus the hind foot is decidedly more than two-fifths the head and body instead of only one third or even less (two-sevenths). The free portion of hind. Fig. 31. HOLBKOOKIA PROPINQUA BAIRD AND GlKAED. X 3. Cat. No. 15669, * toe reaches far behind the occipital plate from snout, instead of only to about its middle. The plates on lower jaw margining the under labials are smaller, those on the temples fewer and larger, the two series being about equal; in H. maculata the case is reversed, and the upper plates are smaller and more numerous. The coloration is much the same. The indigo-black patches on the sides, however, are much more lengthened, forming short, oblique cres- cents, running up into the gray of the sides, the convexity anterior. They are about four times as long as wide, instead of mere oval blotches. There is very frequently a third, more posterior and less distinct, one. The female has quite a decided light stripe between the fore and hind legs, the lateral bars more vertical, shorter, and less Please note that these images are extracted from scanned page images that may have been
