METAMORPHOSES OF ANIMALS. 



Ill 



hibit a much greater diversity in their development than 

 the Lamellibranchiata. Even among the terrestrial and 

 aquatic Pulmonata there are striking differences. Some 

 of the Pectinibranchiata are remarkable for the curious 

 cases in which their eggs are hatched and the young de- 

 veloped, to an advanced state of growth. The cases of 

 Pyrula and Strombus are among the most extraordinary 

 of these organic nests. The embryology of Cephalopoda 1 

 has been illustrated in a masterly way by Kolliker.
