and the temporal bone is broader and more triangular — which made 

 me believe it to be a distinct species before I obtained the cervical 

 vertebrae. 



M. Dcsmonlins, in describing this species, pointed out the most 

 important character of the genus, viz. the length of the pectoral. 



The following species are prol^ably Mctj(q->term(e, but they are too 

 imperfectly known to determine to what genus they belong. 



1. Megaptera Novae-Zelandiae. 

 The tympanic bones very like those of M. hnghnana, but shorter 

 and more swollen, and the periotic bone broad and expanded ; the 

 rest of the skeleton, unfortunately, is unknown.

Ear-boues of Megaptera NovfP-ZelamJice. 



The specimens in the British Museum of the bones of the car, with 

 tympanic bones attached, were sent from New Zealand by Mr. Stuart, 

 and are very like these bones in the Mer/aj/tera longimana from 

 (Jreenland in the Museum collection, but differ in the tympanic bone 

 being rather shorter and more swollen. The latter is nearly regu- 

 larly oblong, and very convex at the upper part, with a somewhat 

 liemispherical outline, and rather wider below.
