N. Annandai^e : Report on the Batoidei. 



descriptions, including the measurements given, have evidently, in many cases, been 

 based solely on badly stuffed Museum specimens, and the figures reproduced have 

 had the same foundation. 



It may be well to give a definite statement as to the measurements recorded in this 

 paper. Considerations of time and space have rendered them less complete than I 

 would have liked, for expedition is necessary, as well as a considerable amount of spare 

 room, if several large rays preserved in rapidly melting ice are to be measured in a 

 tropical climate before they can go bad, especially if a proportion of them are finally to 

 be preserved as museum specimens. Whenever possible, moreover, photographs and 

 water colour sketches have been taken as well as the measurements, in order that an 

 accurate record of the colours and outlines of the different species may be preserved. 

 The measurements themselves have been taken with a tape across or along the speci- 

 mens, — not from point to point. This method has been adopted as providing a more 

 accurate standard for comparison than that of measuring from point to point. Ex- 

 cept when it is otherwise stated, the measurements have been taken on the fresh speci- 

 men before it has been dissected. 



The illustrations, except when it is otherwise stated, are reproductions of photo- 

 graphs of frozen specimens. 



The following list contains the names of the Batoidei as yet recorded or here 

 mentioned as occurring in the seas of British India and Ceylon. I have not dealt 

 further, however, with most of the deep-sea forms.
