 blunt, conical, the posterior one 8 mm. in diameter and project- 

 ing 8 mm. above the dried gum. 



(2) Pelorus Sound. — Figured by Waite. It is strange that, 

 the famous cetacean known as "Pelorus Jack" should not have 

 been mentioned in scientific literature until Waite in a short

 published a photograph showing the contour of the dorsal fin 

 and flukes. It has an extensive litei'ature in newspapers and 

 magazines. A special booklet by J. Cpwan has been devoted to / 

 it, while an article on " Pelorus Jack— Tuni-Rangi," by W. T. 

 Downes, appears in the Journal of the Polynesian Society, 



vol. xxiii. p. 176, 1914. Both these give the Maori legend
