SMOLTS 25 
University are two examples, 23°5 and 28°0 cm., 
which Professor Collete informed him had been 
found in Christiania fish market amongst some 
young mackerel. 
In 1904 there came into my hands a young sal- 
monid, 14 inches long and 154 ounces in weight, 
which had been captured by Mr. Milne, salmon 
tacksman, at the mouth of the Galway river, in 
Ireland, and who was kind enough to send the 
specimen for my inspection. I submitted the fish 
to Mr. Boulenger, of the British Museum, who, along 
with his colleague, Mr. Regan, agreed that it was a 
specimen of salmo salar. I described and figured 
the fish as such,* but pointed out the rather notice- 
able depth of the caudal peduncle, and that in this 
particular the fish resembled the condition commonly 
found in sea trout. In the total length the small of 
the tail (caudal peduncle) was contained 112 times, 
instead of from 15 to 15:9 times as in the smallest 
grilse I have been able to collect in recent years. In 
other respects the characteristics of the fish are 
clearly those of salmon. In the way of hearsay 
evidence one might mention a few similar occur- 
rences of apparently stray specimens linking the 
smolt and grilse. I may mention only one, which 
the late Mr. Anderson, salmon tacksman in the Firth 
of Forth and fishmonger in Edinburgh, communi- 
cated to me, In his father’s time, he informed me, 
a fixed net used to be worked at Queensferry, and 
while he was present, in June 1863, two small grilse 
were caught each weighing # lb. Instances like
