outer convexity there was a small rough fibrous mass, about the 
size of a pea, in which were imbedded a number of very small carti- 
laginous plates,” which he thought evidently represented the femur, 
I examined with care the corresponding part of the bone in this 
animal. I found several minute nodules about the size of small 
shot, which had been cut across in the process of removing the pelvic 
bone. They were attached to the convex border by fibrous bands. 
To the naked eye they ha,d a cartilaginous appearance, but when 
examined microscopically they were seen to consist of fibrous tissue. 
In all probability the apparent nodules were the ends of small 
tendons, which had been cut across transversely close to their 
attachment to the pelvic bone. I may mention that many of the 
tendons in this animal have a dense homogeneous character, and in 
section look to the naked eye somewhat like cartilage. 
In the following table the dates, localities, and other particulars 
of the properly authenticated Scottish specimens of Balcenoptera 
rostrata are summarised.
