been killed by the explosion of gunpowder in a wreck in tke Hoogly. 

 At Mongliyr, a certain caste occasionally catch them ; and many are 

 stated to be killed in Dacca by a peculiar tribe called Garwarus, who 

 spear them and otters. They eat the flesh and biirn the oil, which is 

 also used in i-heumatism. 



A long account of this animal, with copious anatomical details by 

 Erichson, and translated by Dr. Wallich, is to be found in the number 

 of the " Annals and Magazine of Natural History " quoted above. He 

 considers it most nearly allied to Hyperoodon, with relations to the South 

 American genus Inia, also found in rivers. The very minute eye, with 

 the very small or almost rudimentary state of the optic nerves, show that 

 this dolphin must be considered to occupy among whales the same place 

 as the mole does among insectivora, and that it seeks its food in places 

 devoid of solar light, owing to the muddy state of the river. It is, 

 however, occasionally found in moderately clear water in the higher 

 parts of the Ganges. 



The following species is pronounced by Blyth to be conspicuously
