Dr. J. E. Gray, F.R.S., in the Chair. 
The Secretary read the following letter, addressed by Dr. H. Bur- 
meister, of Buenos Ayres (Foreign Member), to Dr. J. E. Gray, con- 
taining the description of a new species of Whale, proposed to be 
called Balenoptera patachonica, together with some particulars as to 
specimens of certain other Cetacea in the Museum of Buenos Ayres. 
Dr. Gray stated, in reference to the new Whale, that it was of 
much interest as being the first well-described Fin-Whale from the 
southern hemisphere. Dr. Gray considered it evidently a typical 
species of the genus Physalus, distinguishable from all the northern 
species by the shortness of the lateral rings compared with the dia- 
meter of the bodies of the cervical vertebree.
