:268 SIR c. ELIOT on nudibranchs [Nov. 29, 



What induces me to this belief is the inconsolable behaviour of the 

 remaining one of a pair should the other be killed, no matter 

 whether the survivor be the male or female. It is really touching. 

 I shall never forget the moaning sobs of the mate of the Lion 

 killed N.W. of Kibwezi dviring the entire succeeding night, nor 

 the continuous melancholy roaring of the mate of thf* Lioness 

 killed in Henga in December 1893.
