Note by Dr. J. E. Gray, F.E.S. &c. 



This is evidently not only a whale that has not yet been 

 described, but it is also the type of a new genus, peculiar for 

 the shortness of its pectoral fins, its plaited belly, and low 

 recurved and pointed fin placed over the vent, and very 

 peculiar among all whalebone-whales for the form of its 

 bladebone (see figure). 



The sulphur-bottom of New-Zealand is very distinct from 

 the sulphur-bottom of California, which is named Sibbaldius 

 sulphureus by Cope. It is evidently the type of a new genus, 

 and may be entered in the catalogues as Stenobalaina xantho- 

 gaster.
