no. 53 Finback ♀ July 24/10 Aibawa a dark whale. Total length snout to notch along side = 6 31' 6" Flukes to post. mast. Fectural = 45' " " dorsal (port.) = 15' 5" Snout to eye = 14' 6" These measurements were taken by myself with the cutter's line no. 54 Finback ♀ July 25/10 Aibawa a rather dark whale. Behind the anus the gray of the sides covers all but a very narrow strip on the ventral edge of the peduncle (it comes down further than usual on the sides). The white ventral line in its widest place behind the anus is only 18" wide. The points extending toward anus are well marked. Where the gray portion of the side of throat & breast shade into the white ventral region they had turned to a light sepia by the time it was brought to the station having been in the sea for a considerable time. I have seen the same thing present in many other finbacks where they had been for some hours in a strong sun. This will explain
