the St Andrews and 1885 specimens. Owing to its small transverse 
diameter the internal carpale articulated by its distal border only with Mrv, 
whilst My was jointed to its ulnar border and to the ulnare in the proxi- 
mal row through an intermediate band of pisiform cartilage. The internal 
carpale represented perhaps only C 4 , whilst C 5 was not differentiated in the 
carpal cartilage, nor was a pisiform bone ossified in the cartilaginous inner 
border of the carpus. 
Digits . — Each of the five digits of the St Andrews animal consisted of 
a metacarpal bone M, and one or more phalanges, Ph. The metacarpal of 
the pollex Mi was a slender cylindriform bone 26 mm. long ; at the free end 
was a nodule of cartilage which represented the phalanx. The metacarpals 
of the other digits were flattened ; M m was the longest, 51 mm., My was only 
25 mm. long, and was set at an angle to and articulated with the distal 
border of the carpale, which represented C 5 . As some of the phalanges had 
been lost their exact number cannot be stated, but they were probably the 
same as in the 1885 specimen, viz.: D n , five phalanges; Dm, four; D IV , 
three ; Dy, two, and the longest digit was the index. 
In the Dalgety Bay specimen, however, D m had five phalanges in one 
manus though only four in the other, and Diy had four phalanges, of which 
the terminal was no bigger than a small shot. 
The constitution of the manus in the St Andrews and Dalgety 
Mesoplodons may be expressed by the following formulae, the number of 
phalanges in the St Andrews specimen being taken from the 1885 specimen: —

In addition to the specimens of Sowerby’s whale found on the coast of 
Scotland described in this communication, we owe to Mr Wm. Taylor of 
Lhanbryde notes of other examples. In 1897 he obtained the skull with 
other bones of a male, about 15 feet long, stranded about 1J mile east of 
the harbour of Nairn.* In September 1899 two females, mother and a

Literary and Scientific Societies at Nairn, July 1898, p. 4.
