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

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

 ran describes it at length. 



M. Pucheran (Eev. & Mag. de Zoologie, 1856, pp. 1 48 & 315) gives 

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

 suniier 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: — ^^ Delphinus plumheus, Duss. Adidte. Taille 

 grande ; couleui" de cors gris plombe ; extremite et dessous de la 

 machou'e inferiem'e blanchatre ; nageoii-e dorsale peu elevee mais 

 allougee ; nageoix-e, pectoral et caudal bien etalees ot bien developpes ; 

 formule dentaire 39 ^-^.-^^ 3- ; jeune bord de la machoire superieure et 

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



" Hab. Cote de Malabar." 



The Delphinus ptlumheus, although very common on the Malabar 

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

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

 Laid by the Malays of the Peninsula. 



" The stomach of a single young specimen observed contained 

 remains of small fish, apparently Clupea and Gliiphisodon ccelestimis, 

 Cuvier." — Cantor, Malay Mammalia, Journ. Asiat. Soc. xv.
