The CocJilostyla of the Philippines lay their eggs at the tops of the great forest trees, folding a leaf together to serve as a protection. The eggs of the great tropical Bulimus and Achatina, together with those of the Macroon group of Helix QHelicophanta^ Acavus, Panda) are exceedingly large, and the number laid must be decidedly less than in the smaller Pulmonata. Buli- mus ohlongus^ for instance, from Bar- bados, lays an Qgg about the size of a sparrow's CFigf- 38), Achatina si7iis- FiG. 38. —Newly-hatched young ^ i • ? rrn and egg of Buiimusobiongus trorsa as large as a pigeons, ihe Miiii., Barbados.

America (probably maxi- mus or jjopelairanus) which measures exactly 1|^ inch in length. The Limnaeidae deposit their eggs in irregular gelatinous masses on the under side of the leaves of water-plants, and on all kinds of debris. The Racliiglossa or marine carnivorous families lay their eggs in tough leathery or bladdery capsules, which are frequently joined together in shapes which differ with the genus. Each capsule contains a varying number of ova. The cluster of egg- capsules of Buccinum undatum is a familiar object on all our sandy coasts. The capsules of Purpura lapillus are like delicate pink grains of rice, set on tiny stalks. They are not attached to one another, but are set closely together in groups in sheltered nooks of the rocks. A single Purpura has b
