In the R. Natural History Museum in Stockholm a con- 

 siderable number of skeletons of whales from different seas 

 are kept, and among them are to be found several more or 

 less rare specimens in a very complete state, also provided 

 with the pelvic bones which otherwise very often are missing 

 in the specimens of the museums. T have had the intention 

 to publish an osteological description of some of these skele- 

 tons but have not vet had time to get it ready. For certain 

 reasons I am compelled to let the following notes appear 

 in advance, and although they are not very complete, they 

 give information about the pelvic rudiments of some species 

 in which the stage of development of these bones was 

 unknown, and they may thus serve as a complement to 

 Abel's paper^ on »Die Morphologie der Hiiftbeinrudimente 

 der Cetaceen». 



The pelvic bones of Bältena anstralis Desmoul. 



Through the courtesy of Captain C. A. Larsen a skeieton 

 of the Southern Right Whale was obtained at South Georgia 

 some years ago by Mr. E. Sörling then assistant taxidermist
