NATIVE NAMES OF ELASMOBRANCH FISHES. 



We add a list of such uative names of Elasmobranchs in use in the North of 

 Ceylon as we have so far been able to ascertain, together with the scientific 

 designation. Where possible the signification of the native names is given. 



We are well aware that the list is far from complete. It is offered in lieu of 

 anything fuller being in existence, and in the hope that it may prove of assistance 

 to anyone who may pursue investigation in Ceylon touching the Elasmobranchs.
