 Physeter simus, Owen, Trans. Zool. Soc. vol. vi. p. 30, t. 10, 11, 12, 

 13, $ (not skeleton, t. 11. f. 2). 



Inhab. Australia, India. Length 10 feet, young. 



The difference between Kogia and Euphysetes does not depend on 

 the sex of the animals. Mr. Krefft described a male, and Professor 

 Owen a female specimen ; the latter mistook the two drawings of 

 the same specimen for the two sexes, deceived by certain additions 

 surreptitiously made to Mr. Elliot's drawings ; but the additions, 

 especially the penis, are not represented on the plates, and the artist 

 (Mr. Willis) says he received no directions to leave out any part of 

 the drawing, and accurately copied them. The measurements given 

 in the paper do not agree with those in Mr. Elliot's notes made from 

 the living animal ; and reference to them would have prevented aU 

 this confusion.
