called “‘ SteypireySr” by the Icelanders. 337 
the same finger, of the skeleton formerly belonging to Lidth de 
Jeude, is only a consequence of an injury ; and the number of 
the phalanges of the four fingers in Balenoptera Sibbaldit 
may be stated to be either 4, 7, 5, 4 or (perhaps) 4, 7, 6, 4. 
When, now, we compare with these the number of the pha- 
langes in the pectoral fin of the “ Tunnolik,” I must first 
remark that the figure of the latter given by Eschricht is not 
quite correct; nor is his statement in the text of the number 
of the phalanges* perfectly accurate or quite in accord- 
ance either with the actual conditions or with the figureyt. It 
is much to be regretted that this pectoral fin, which, at 
the time when Eschricht received it, was quite complete, has 
afterwards suffered some damage: the tips of the fourth and 
fifth fingers are lost, and there are now only four phalanges 
in the first, and two in the second, of these two fingers. 
It is therefore impossible to state exactly how great the 
error in Eschricht’s figure really is; but there are certainly 
only four phalanges in the second finger (the index), and 
but six in the third; and though the fourth finger, as I have 
said, is incomplete now, and the original number of the pha- 
langes cannot be stated, yet it may at any rate be positively 
inferred, from the form and length of the remaining part, that 
it was never so long as the third: therefore the woodcut in 
Eschricht’s memoir is incorrect in representing it as being 
even a little longer than the latter; but what the cause of the 
mistake really is, whether the artist has drawn too many pha- 
langes, or made the phalanges really existing too long, must be 
left undecided. The formula for the number of the phalanges 
in the hand of the ‘ Tunnolik”’ will therefore be 4, 6, 6 (?), 
3(?); and as the woodcut cannot be thoroughly depended 
upon as to the comparative size of the single phalanges, I 
here add the measurements of the hand in Danish inches :—
