Africa, as 60 ft. Scammon states that in the Pacific the females frequenting the neighbourhood of Tongataboo, Friendly Islands, are usually of large size, and that This, how- the largest of them captured in 1871 was adjudged to be 75 ft. long. ever, is far behind that huge cow which was captured at Bermuda in 1665, and which is stated to have been 88 ft. long (Phil. Trans., vol. 1, p. 11, 1885): both Van Beneden and True were inclined to regard this remarkable record as substantially truthful (True, Whalebone Whales of Western North Atlantic, 1904, p. 214).
BODILY PROPORTIONS.
Major Barrett-Hamilton recorded, whenever practicable, each of the following dimensions of the humpbacks examined the dimensions are numbered so as to cor- respond with those taken from finners and blue whales :--
1. Total length from tip of mandible to notch of flukes in a straight line.
2. Projection of tip of mandible beyond tip of snout.
3. Length from tip of snout to notch of flukes in a straight line (dimension
1 less dimension 2).
4. Greatest width at flippers.
6. Tip of snout to centre of eye.
7. Tip of snout to centre of blowhole.
8. Tip of snout to axilla.
9. Centre of eye to centre of ear.
10. Tip of mandible to gape.
11. Notch of flukes to centre of anus.
12. Notch of flukes to centre of penis or clitoris.
13. Notch of flukes to centre of navel.
14. Notch of flukes to posterior insertion of dorsal fin.
15. Notch of flukes to insertion of flukes.
16. Vertical height of dorsal fin.
17. Greatest length of pectoral fin to head of humerus.
18. Greatest width of pectoral fin.
19. Median length of severed head from plane of condyles.
20. Greatest width of head.
These measurements are given in full in the tables which accompany this report.
Dimensions 2 to 20 have been reduced to percentages of the total length, and in the following table a summary of these percentages is given. For comparison, corresponding percentages relating to the humpbacks of the North Atlantic and the Pacific have been added where possible. For the North Atlantic the data collected by True have been used, together with the measurements made in 1913, by Mr. J. E. Hamilton, of a male humpback captured at Belmullet on the west coast of Ireland. The figures relating to the Pacific are derived from the measure- ments published by Scammon.
