" By the kindness of the late Dr. Horsfield, the types of the species 

 of Indian Fishes described by Dr. Cantor have been examined at the 

 Museum of the Hon. East India Company. 



" WTiercver I have not had an opportunity of examining the species, 

 and have been obliged to borrow the characters for a diagnosis from 

 another description, I have added the authority. There remain, 

 however, species which are either insufficiently described, or founded 

 on characters so slight that it is doubtful whether they will stand 

 as species, — or which are established from figures not executed by, 

 or under the inspection of, naturalists : these are mentioned in notes, 

 without a description, and with the synonymy only. Whoever has 

 gone through the labour of examining such descriptions, of making the 

 best of them, and of determining fishes by them, wiU know the amount 

 of time fruitlessly spent, and wiU understand how to appreciate the 

 more recent accounts of Bleeker, which combine with the distinctness 

 of a diagnosis the accuracy of a description. 



'* To conclude, I add some explanatory remarks on my way of taking 

 the measurements of specimens, of counting the scales, &c. : — 



" 1. The heigJU of the body is always its greatest depth. 



" 2. The letKjth of the head is the distance between the end of the 

 snout and the posterior extremity of the hony operculum. The lenyth 

 of the snout is the distance between the end of the snout and the 

 vertical from the anterior margin of the eye.
