of teett in the lower jaw in the place of the haleen, and with a small 

 dorsal on its back, again appears in Duhamel (iv. t. 9. f. 2), under 

 the name of " Baleine en Guinee," from the Baver Gaboon, where, 

 he says, it is called Grampus by the English.

The Right Whale of the Bay of Biscay (B. Biscayensis) is regarded 

 as a different species by Eschncht and Van Beneden. — Gray, P.Z.S. 

 1864, 200. 



Cuvier observes that the Right Whale was formerly taken in the 

 Gulf of Gascony, but that now it is only found on the shores of 

 Greenland, Iceland, and Spitzbergen. (See Cuv. Oss. Foss. ed. 4. vii. 

 252 ; also Eschr. & Reinh. Kord. Hvaler, p. 479, note.) 



" MM. Eschricht and Reinhardt (Om STordhvalen) have conclu- 

 sively proved that the habitat of B. Mysticetus is, and always has been, 

 exclusively confined to the Polar Seas, and therefore that it has no 

 claim to a place in the European fauna. The Right Whale of the 

 Worth Atlantic, formerly chased by the Basque whalers, belongs to 

 this section (Euhalcena) of the tamUj."— Mower, P. Z. S. 1864, 391. 



M. Eschricht observes, " Le squelette de Pampelune m'occupe tout 

 plein, m'ecrit-il k la date du 18 mai dernier. C'est tout ce qu'il y a 

 de plus curieux. II est presque monte, et I'enorme difference avec 

 le Mysticetus depasse tout ce que j'en avals juge lors de mon sejour k 

 Pampelune. Figurez-vous, ajoute-t-il, qu'U n'est pas plus de'veloppe 

 que le squelette d'un Mysticetus de peine un an, I'ossifieation des 

 vertebras n'est pas encore avancee jusqu'aux apophyses transverses, 

 et les arcs qui ne sont pas meme unis des deux cotes sont encore 

 separes du corps et cependant la eolonne vertebrale a la largeur du 

 Mysticetus de trois ans et demi." (See also Eschricht " Sur le De- 

 veloppement du questionnaire relative aux Cetaees," Actes de la Soc. 

 Linn, de Bordeaux, xxii. livr. 4.) 



This theory appears to require further examination. Icebergs are 

 annually carried out from the Arctic Seas to the North Atlantic, and 

 it is probable that Right Whales may sometimes accompany them. 



I have not been able to find any details of the skeleton at Pam- 

 peluna, so that I have no authority for placing B. Biscayensis in a 

 different genus from B. Mysticetus.
