 Figure 6 represents the ventral side of the throat in a Finback 

 whale {Balmiopteraphysahis). The folds are seen to start from 

 the border of the lips as single plications, but as the expanse of 

 the throat increases posteriorly they fork dichotomously in a 

 fairly definite manner, so that the number of folds at a given 

 part of the center of the throat is greater than that at either 

 end of the corrugated area. Posteriorly the folds run together 

 m reverse order, so that a reduction is effected similar to that 

 found at the anterior region of the throat. Curiously, however, 

 forkmg may take place in either direction, so that the two new 

 branches may point either anteriorly or posteriorly, but the lat- 

 ter mode of branching was not noticed in the posterior part of 

 the area covered by the folds. Sometimes, also, two folds run- 

 nmg parallel to each other may be connected by a short cross- 

 fold, which aids in binding all together. 



Up to the time of my visit the whaling steamer Puma, oper- 

 atmg at Chaleur Bay and at Placentia Bay, had taken in 1903 

 107 Sulphur-bottoms, 66 Finbacks, 14 Humpbacks, and i Pol- 

 lack whale i^B. borealts). The last named was captured in Pla- 

 centia Bay, as were the four taken in 1902.
