Delphinus plumheus. — The adult specimen of D. plumheus, figured 

 by F. Cuvier (Mamm. Lithog.), is in the Paris Museum. M. Puche- 

 ran describes it at length. 



M. Puchcran (llev. & Mag. de Zoologie, 1856, pp. 148 & 315) gives 

 some additional particulars of the specimen received from M. Dus- 

 sumier in the Paris Museum, on which this species was originally 

 described, and corrects some part of the description of M. F. Cuvier. 

 He describes it thus: — ^' DeJphimis plumheus, Duss. Adulte. Taille 

 grande ; couleur de cors gris plombe ; extremite et dessous de la 

 machoire inferieure blanchatre ; nageoire dorsale pen elevee mais 

 allongee ; nageoire, pectoral et caudal bien etalees et bien develoj^pcs ; 

 formule dentaire 30 331.34 37 ; jeune bord de la machoire supcrieure et 

 dessous du corps jusqu'a la moitie de la queue de couleur blanchatre. 



" Hab. Cote de Malabar." 



The Delphinus plumheus, although very common on the Malabar 

 coast and Penang, and rather heavy in its movements, is rarely caj)- 

 tured, except by chance in fishing-stakes. It is called Parampuan 

 Laut by the Malays of the Peninsula. 



" The stomach of a single young specimen observed contained 

 remains of small fish, apparently Clupea and Ohiphisodon caelestmus, 

 Cuvier." — Cantor, Malaij Mammalia, Jouni, Asiat. Soc. xv.
