234? THE KANGAROOS. 



is scarcely half grown, there is a brown mark along 

 the middle of the tail beneath. It is from the same 

 locality as the adult specimen last described. 



Desmarest, in a foot-note accompanying the account 

 of M. Eugenii, says " nous croyons pouvoir rapporter 

 ce nom a un Kanguroo de la collection du Museum, 

 qui a ete etiquete Kanguroo des iles Saint Pierre, et 

 qui, par sa taille, ressemble a I'espece trouvee dans 

 ces lies par Lesueur et Peron. Ce Kanguroo est 

 maintenant indique comme un jeune de I'espece a 

 cou roux" (M. rujicollis.') 



This same specimen is again referred to by Messrs. 

 Geoffroy and F. Cuvier, in their account of the Hal- 

 mature Thetis. They say the species to which they 

 give this name has long existed in the Paris Museum, 

 but the resemblance of its colouring to the M. rujicollis 

 caused it to be mistaken for the young of that species.
