Description.-This species is very closely allied to the preceding one, having like it short limbs, scarcely webbed toes, a very much developed parotoid-like gland on the upperside of the calf, and the first finger not extending beyond the second ; it approaches B. viridis in the simple subarticular tubercles under the toes, the very distinct tympanum, and large parotids. It must be regarded as an intermediate form between B. calamita and B. viridis. The head resembles in shape that of B. calamita, but is relatively larger and its breadth a little less with regard to its length. The nostrils are equally distant from the anterior corners of the eyes and the tip of the snout; and the space between them equals that which separates one of them from the lip. The eyes are a little nearer to the tip of the snout than to the angles of the jaws. The interorbital |
