Jaguars were not seen or heard, except one reported by the mail carrier who runs between Aremu and Perseverance Landing. Some years ago an Indian near here found a litter of jaguar cubs containing two normally colored and one black individual. The latter was purchased by a colonist and sent to the London Zoo. A dull-colored, harmless snake, four feet long, with two rows of keeled scales along the back, was the only serpent we found in or near the clearing. Lizards were everywhere and one very large iguana inhabited a bit of wood-road, but evaded all our efforts to add him to our mess pot. The Amphibians alone in this region would well repay months of study. Our brief visit gave us only a glimpse of them. The commonest frog in the jungle near the clearing was a medium sized, dark-bodied one (_Dendrobates trivittatus_) with green legs and two pale green bands, one running around the front edge of the head, back over the eyes and down the sides of the body; the second line being beneath the first. The under parts were covered with blue lines and mottlings. The first half dozen seen were normal in appearance, but then one was encountered which instantly drew my attention. A closer look showed that the back of the animal was covered with a solid mass of living tadpoles, each over half an inch in length. When I urged him into a jar, two tadpoles were scraped off and wriggled vigorously. When put into water they sank to the bottom and made no attempt to swim, although the tail fins were well developed and there was as yet no trace of limbs. I kept this frog in a box with wet earth and a puddle of water, and two days later half the tadpoles had left his back and were swimming strongly in the muddy water. They were attached to the back of their parent only by their sucking disks, and the object of the strange association seemed only temporary and not intended to last until the tadpoles became adult. They would probably drop off and swim away one by one when their father entered some forest pool. This species of frog was very active and capable of remarkably long jumps. As I shall mention later, the sharp eyes of my Indian hunter spied a most remarkable frog in the jungle one day, which I brought home in my pocket. Its scheme of protective form and color was perfect—the hue of dried leaves and withered mosses, with deeply serrated sides and a high irregular ridge over each eye. I placed it among some dried leaves and tried to focus on it with my Graflex, but could not find it. Then I stooped down and although the frog had not moved and I knew the square yard within which it was resting, it took me a full minute before I located it, and optically disentangled it from its surroundings. I have never seen such a case of complete dissolution and disappearance. When I alarmed it, the frog closed its eyes—thus obliterating the dark spots of its irides, and then little by little opened them again.
