History and Etymology for Risso's dolphin

after Giuseppe Antonio (Joseph Antoine) Risso †1845 naturalist born in Nice

Note: Risso contributed a description and drawing of the dolphin, apparently never published on their own, to the French zoologist Georges Cuvier (1769-1832), who briefly described and illustrated the dolphin on the basis of Risso's account in "Rapport 
 sur divers Cétacées pris sur les cÎtes de France 
," Annales du Muséum d'historie naturelle, tome 19 (1812), pp. 12-13 and plate 1 (under the taxonomic name Delphinus griseus). A later synonym was Delphinus rissoanus (1827), on which the current common name may be based.
