very much foreshortened : as Dr. Hector remarks, it is not like the macerated 
bone, which has all the characters of the scapula of B. musculus. So that, 
on examinalion, there seem to be positively no definite characters upon 
which the Port Underwood whale ean be separated from B. musculus. This 
is evidently Dr. Hector's opinion,* although he still adheres to the name 
B. australis. 
In Haast's New Brightont specimen the position and form of the dorsal 
fin were unfortunately not ascertained; in every other respect the agree- 
ment with B. musculus is quite close. 
There seems therefore to be, as far as the information at my disposal 
goes, complete specific identity between at least two well-authenticated 
Specimens of the Southern Rorqual and its northern representative. And 
it would further appear that in every respect in which the Nelson specimen 
differs from B. musculus, it also differs, and in the same manner, from the 
so-called B. australis. 
On the whole it seems to me that one is justified in assigning the 
present specimen, as well as the Port Underwood and New Brighton speci- 
mens, to Balenoptera musculus, at least until the accurate examination of 
both externa] and internal characters in the same individual has definitely 
proved the existence of a distinct species of Southern Rorqual. 
In the skeleton as mounted the intervertebral ligaments are represented 
by pads of felt, and the following missing bones by wooden models :—

The three posterior chevron bones (14th-16th). 
Both pelvic bones (modelled from Haast’s figure of the pelvis of 
the New Brighton specimen).
