APPENDIX.— November 23, 1872. 



In drawing up the Historical Sketch of Cuvier's Hollow-beaked Ziphius 

 and of Sowerby's Whale, I omitted to refer to a brief description by Pro- 

 fessor A. W. Malm, in a memoir, entitled " Hvaldjur i Sveriges Museer 

 ar 1869,"* of the skeleton of a specimen of each of these rare Cetaceans 

 preserved in the Natural History Museum in Goteborg, Sweden. Although I 

 possessed, through Professor Malm's great courtesy, a copy of his elaborate 

 memoir, yet I had not, owing to its being written in the Swedish language, 

 mastered its contents. My friend, Professor Flower, having within the last 

 few days referred me to Malm's description of these specimens, Dr Charles 

 Wilson has very kindly translated for me the passages in which they are 

 described, and as a knowledge of Swedish is by no means general amongst 

 British zoologists, I think it desirable to append a statement of the more im- 

 portant particulars which Malm has recorded. 



The specimen of Ziphius cavirostris was found stranded at Holma, near 

 Gullmarsfjard, Sweden, on 22d April, 1867. It was supposed to have been 

 suffocated by getting under the ice which had formed about Christmas, and 

 was so putrid that only a hand's breadth of dark-grey skin remained. It 

 was a female, and measured 22 feet 2 inches (Swedish) in length. 75 kanns 

 (7500 cubic inches) of oil were obtained from it. In the stomach a tangled 

 mass of a transparent worm, 3 feet long, was found, which apparently belonged 

 to the genus Echinorhynchus. The total length of the skeleton, including the 

 cranium, was 6140mm., to which an additional 34mm. must be added for 

 the projection of the lower jaw beyond the beak : — 



Length, of cranium ........ . 1015mm. 



„ „ mandible ......... 887 „ 



„ „ symphysis 205 „ 



„ „ greatest breadth of skull . . . . . . . 570 „ 



Two teeth, similar in size and shape, were in the lower jaw, but only the point 

 of each was tipped with enamel. The epiphyses were anchylosed to the 

 vertebral bodies. The vertebral formula was — C 7 D 10 L 10 Cd 19 = 46. The 

 four upper cervical vertebrae were anchylosed together. The sternum was 

 subdivided into five pieces, only the two posterior of which were completely
