The inner cuneiform tubercle is rather small, but has a rather prominent compressed edge. External tubercle, none. A thick tarsal fold. There are no large warts on the skin, but there are occasionally minute warts and folds on the superior face of the Fig. 101. Rana vircsceng hraclvjccphala, Nn. 50922. Fort W^alla "Walla, "Wash. Ter.; \. In life the color of the superior surfices is green. The dorsolateral ridges are light yellow, and so is a stripe from the end of the muzzle, which passes above the lip and below the eye and tympanum to above the middle of the humerus. There are two rows of large, rounded dorsal spots between the dorsolateral ridges, which are edged with greenish-yellow. There are two similar rows on each side, of which the inferior is the smaller, which are not regularly arranged. There is a spot on each eyelid and one on the end of the nose above. There is a light band, frequently broken into spots near the edge of the upper lip. There is a brown s])ot on the elbow and one on the front of the cubitus. The bauds seen on the front of hnmerns in R. v. vircsccns is here an illy defined spot. On the superior face of the femur there are three brown spots, but there is no longitudinal brown band in front of these spots, as is usual in the two other subspecies of the R. vircsccns. There are three complete wide brown eross-bands on the femur, and sometimes four. Frequentl
