A. biporcatiis, exhibiting several rather short supraciharies grading into large scales that tend to grade again into granules, presents a condition hardly more frequent than that of A. fraseri with its series of quadrate scales along the whole supraciliary margin, the first of these sometimes elongate. 3.

Scales around interparietal. In general, the degree of enlargement of scales around the interparietal is a good specific character in Anolis. Particularly valuable may be the degree of enlargement of the scales posterior to the interparietal as compared with the adjacent dorsal or supratemporal scales. There may be rapid intergradation of enlarged scales lateral to the interparietal into much smaller dorsal and supratemporal scales, or the scales behind the interparietal may be sharply and conspicuously larger than dorsal or supratemporal scales (as in some apoUinaris). The two subspecies of A. biporcatus difl'er in this regard. A. apoUinaris is variable; perhaps the variation is geographic, but there is not enough material to say. 4. Ear shape and position. The ear of apoUinaris is quite dif- ferent from that of either southern or northern biporcatus. It is.
