. The Cambridge natural history. Zoology. 220 ANURA of this " Sapo " iu Puerto Eico on the 4th of iSTovember ; on the 25th the young showed the first signs of hind-limbs, on the 3rd of December of fore-limbs, and on the 7th of the same month they began to climb out of the water. Paludicola is a semi-aquatic genus with some eighteen species, ranging from Mexico to Patagonia and across the Andes into Chili. Some of them have a peculiar gland on the lumbar region, or large, flat warts on the back, sometimes arranged iu longi- tudinal folds. The toes are slightly webbed, or free, according to the more or less pronounced aquatic habits. P. fuscomcwtdata, an inhabitant of Southern Brazil, Paraguay, and Uruguay, is a short-limbed frog, with spreading slender toes and a small head. There are shovel- shaped, black, horny tubercles on the metatarsus. The general colour is olive above, with darker markings and con- fluent white-edged spots; the limbs are cross - barred; the lumbar glands are black, with a white margin in front. The male has a vocal sac. Budgett ^ gives the following account of its habits :— The peculiar cry, which is so con- stantly heard in the neighbourhood of shallow pools in the Paraguayan Chaco, and resembles that of a kitten, is pro- mamiata, x 1, with'vocal duccd by the alternate inflation of throat sacs par y e . ^^^ abdomen. When fully inflated, the frog appears to be the size of a golf-ball, but, if startled, instantaneously shrinks to one-fifth of that size, so that it seems to have vanished. It has also the power of ventriloquising. The food consists largely of water-beetles. In the spawning time it was found at night floating on the surface of pools in the distended condition, and crying to the females in a most mournful way. On coming to the surface it fills its lungs with a few gasps, greatly distending the walls of the abdomen, and then drives the air into the vocal sacs, causing them to become distended as the body collapses, and g
