I doubt very much though, whether the Acriscan whistle and crepitate too. This would be contrary to Xature, for reasons which are too many for me to explain. X Professor Cope also gives the following anatomical defini-tion of this subspecies: Acris gryllus crepitans. Hinder foot, notincluding the tarsus (that part of the foot above the instep), lessthan half the length of head and body combined; skin tubercleslarger; posterior femoral (hind leg) stripe less distinct.. 10 FAMILIAR LIFE IN FIELD AND FOREST. actly imitated by striking two marbles together, firstslowly, then faster and faster, for a succession ofabout twenty or thirty beats. The noise can not beheard at a very great distance. The little frog is prominently marked on theback with green, and has the same dark triangle onthe crown as that described for the species proper.He remains in the tall grass around the marsh, andseldom if ever ascends a tree or bush. When pur-sued he leaps extraordinary distances and invariablymakes for the water, into which he disappears justas we reach the margin after much clumsy slumpingthrough the bog and vain grabbing at the unattain-able. Only one who has lost a frog thisway knows anything about the sudden men-tal activity of the baffled pursuer as hestands gazing at the mocking ripples.
