IV. On the Occurrence of the Argentine, Anchovy, and other Fishes, on 
the Coast of Caithness ; with a Note on the Termination of the Vertebral 
Column in the Tails of the Salmon tribe. Bj Charles W. Peach, 
Esq., Wick. 
(MuUer's Topknot was exhibited, and also specimens of 
the tails of salmon, smolt, and trout, showing the upward 
terminal turn of the vertebral column.) 
1. Scopelus Humboldtii. (Cuvier.) The Argentine. 
A fine specimen of this really handsome little fish was 
picked up on Shaltigo beach. Wick, on the 15th January 
last, by Mr William M'Leod, pilot. He had kept it in his 
pocket for a day or two before giving it to me, and shown it 
to many as the young of the herring. It is somewhat in- 
jured in the fins by the handling, but, on the whole, is in 
pretty good condition. The spots on the lower part of the 
body are very distinct ; the row above these not so clear ; 
those on the head and gills perfect. Its length about 1| 
inch, depth nearly half an inch. When examining it to 
observe the fins, a great deal of oil oozed out of it, covering 
large spaces on my fingers. In the second edition of Yar- 
reirs " British Fishes," 1851, pp. 161 to 168, I find that it 
has been taken at Orkney, Firth of Forth, Yorkshire, and 
Devonshire, also in the Mediterranean ; and, although not 
abundant, it has a wide range. The dates of its capture are 
recorded in Yarrell,— viz., Firth of Forth, April 1833 ; 
Eedcar, May and March 1841 ; " now, in Caithness in Jan- 
uary 1861. Thus it has been taken in the British islands, 
from midwinter to near midsummer. Mr Couch of Polperro, 
Cornwall, informs me that he has had four specimens sent 
him from a gentleman in Somersetshire, which he intends 
to publish coloured figures of in his new work on the British 
Fishes, now coming out in numbers.
