ON METONYMS. oO 



Liinacldae have tliG foot united with the body; tentacles and eyes 

 as in the snails; mantle small, shield-shaped; shell small or rudiment- 

 ary, usually internal or partly covered by the mantle; in Oncidium 

 there is no shell, not even a rudiment, and the mantle completely 

 covers the animal. 



Lymnaeidae inhabit water or wet places; have a thin horn-colored 

 inopcreulate shell with a sharp lip; the animal has only 2 tentacles the 

 eyes being at their inner bases ; the mouth has a buccal plate, and the 

 odontophore resembles that of Helicidae. 



Those who would satisfy themselves as to the value of the buccal 

 plates and the form of the teeth as characters, should examine the 

 observations on the Terrestrial Pulmonifera of Maine by Edward S. 

 Morse, published in 1864. The numerous and excellent figures here 

 given bring the matter clearly before the reader. The able author may 

 be too fond of multiplying families and genera, but he is an acute 

 observer and has made an important contribution to science. 



It confirms our notion of the value of the character of the order drawn 

 from the adaptation to air-breathing, that there is no common character 

 of the Odontophore throughout the order, but we find its arrangements 

 adapted to the special mode of life of the families, and even in some 

 instances of sub-families or genera. We are also made to observe that 

 the carnivorous character of the Odontophore does not necessarily 

 indicate the highest position as to general development. These facts 

 will be useful to us in the difl&cult inquiry lying before us respecting 

 the subdivision of the great order Pectinibranchiata.

Most readers are aware that the names Erasmus and Melanchthon 

 are not the original native names of the persons who are thus usually 

 designated in history and literature. They also probably know what 

 the original names of these two distinguished men were. They know 

 that Melanchthon is the German family name Schwartzerd, Blackearth,,
