In a future report on the Selachians of the " Golden Crown," the distribution 

 of the Indian Klasmobranchs will be discussed. As Capt. lyloyd ^ has recently made 

 use of all the information at present available in India regarding the Ceratopteridse, it 

 is unnecessary for me to discuss the species of that family, especially as no specimens 

 have been taken by the '' Golden Crown." I may say, however, that an examination 

 of the specimens in the Indian and Madras Museums fully confirms Lloyd's remarks 

 as to the pecuHarities of the Ceratopterid skull.
