The future developiueiit of our knowledge of this genus will be 

 watched with much interest by cetologists. At present tliere is noth- 

 ing- to add to Gray's original description, and no additional specimens 

 have been discovered. 



I concur in Gray's opinion that the two typical skulls are clearly 

 allied to Lagcnorhynchus electra, and it may be found necessary event- 

 ually to include Fcresa in thut genus.
