Lower side of head and breast of female sperm whale. There is considerable difference in the shape 

 of the head of the male and female of this species, a fact which has not been widely recognized by cetolo- 

 gists 



The porpoises were of great interest. 

 Ten specimens were secured comprising 

 four different genera and five species. 

 One proved to be a very extraordinary 

 specimen representing a new genus 

 which differs in many respects from all 

 other members of the family. 



While in Japan it was learned that a 

 whale called the " devilfish" by the Japa-

 the California gray whale, was taken off 



The tongue of the sp3rm whale contrasts strongly with 

 that of the humpback shown in a preceding photograph

 This information was exceedingly in- 

 teresting because, since 1880, this species 

 had been lost to science and naturalists 

 believed it to be extinct. It was im- 

 possible to secure specimens of it at 

 this time, but in the following year I 

 returned to Japan to investigate the 

 so-called "devilfish." As suspected, 

 it was found to be the lost California 

 gray whale and two complete skeletons 

 were secured as well as photo- 

 graphs, measurements and 

 descriptions of over thirty 

 individuals. A very large 

 humpback whale was also 

 taken, and a third killer, to-

 amount of alcoholic material 

 for embryological and histo- 

 logical study. The humpback 

 skeleton was unfortunately 

 destroyed by fire in the sum- 

 mer of 1918 after it had beea
