Globicephalus melas ( Pilot Whale). 
In my previous memoir on Mesoplodon,* so frequently referred to, I gave 
a short description of the carpus of Globicephalus melas. I have again 
studied this specimen, compared it with the descriptions which were 
subsequently published by Max Weber and by Kilkenthal, and have been 
led to modify the opinion which I had previously expressed on the 
morphology of certain of its disto-carpalia. 
In the two hands of my specimen the radial and ulnar epiphyses were 
ossified, but not fused with the shafts. The bony elements of the carpus 
were well formed and dominated the cartilaginous matrix. The radiale 
was 47 mm. in transverse diameter, the intermedium 40 mm. and the ulnare 
24 mm. 
The bone on the radial border of the carpus, which I had previously 
spoken of as carpale 2 , I now regard as carpale x , which necessarily modifies 
the numerical order of the other disto-carpalia, so that the former carpale 3 
now becomes C 2 , and the former C 4 becomes carpale 3 . Again, the bone 
situated in the plane of the proximal ends of the metacar pals, which from 
its rounded form and roughened surface I had regarded as distal carpal C x , 
is now described as the metacarpal of the pollex. This change in opinion of 
the morphology of these bones is based on a fuller recognition of the position 
of the os cent rale, which in the original description was regarded as placed 
between carpalia 2 and 3 , whereas its true position is between carpale 1? C 2 , 
the radiale and the intermedium. The present description follows, there- 
fore, the amended view of the morphology of the bones.
