 The number of Amphibia is less easily determined as the species of 

 Batrachia require careful revision. • The number known is about 100, of 

 which 1 only belongs to the Urodela and 5 to the Pseudophidia. 



The numbers of the Fishes are taken from Dr. Day's work, and are 

 consequently trustworthy.

My principal authority for the Mollusca (land and freshwater) is Mr. 

 Theobald's list printed as a supplement to the Conchologia Indica. I have 

 omitted the estuarine species therein enumerated. Unfortunately I have 

 not the numbers of the different families, and, as I am writing away from 

 books, I can only give the approximate numbers of the classes here. They 

 are — 



Gasteropoda (land and freshwater), 900 



Lamellibranchiata (all freshwater) , 100 



1000
