A curious little tree frog found on the island of Martinique glues its eggs to a leaf, where they form a foamy mass. In this case development is practically completed in the egg and there is no aquatic larval period. Thus some of these forms have practically eman- cipated themselves from any need of an aquatic environment, though they must still Hve in a moist locality. 397, Apoda,—The Apoda, or ceciHans, some- times called blmdworms, are generally distributed in tropical and subtropical countries. They pos- sess neither girdles nor limbs but have concealed dermal scales. They burrow in the earth some- what as does an earthworm and are not unlike an earthworm in general appearance. The anal opening is almost at the posterior end, there being merely a rudiment of a tail. The eyes are also rudimentary and practically functionless, but the animal possesses a protrusible tentacle-hke organ lying in a groove between the eyes and nose by and is inverted in the means of which it feels its Way about. In one action; the insect adheres type found in southern and southeastern Asia the wMr'^^LtTeat^Tci female lays her eggs in masses in a shallow hole is drawn back into the near the water and coils herself about them (Fig. 263). The larval stage is passed in the egg, the larva possessing three pairs of external gills which are lost when it hatches. This larva swims about in the water for a while, coming to the surface for air, but at length the gill clefts close, the tail fin is lost, and the animal bec
