Mr. Jenyns doubts whether these three Species should be 
considered as distinct; but having kept the first and third 
alive in glass vessels, and finding them to manifest very dif- 
ferent habits, I have no hesitation in believing Mr. Yarrcll to 
be correct in his opinion of their being specifically different. 
FIFTEEN SPINED STICKLEBACK. G. Spinachia . 
Jenyns, p. 352. YarrelFs Br. F., vol. 1, p. 87. Common. 
MAIGRE. Sciama Aquila . Jenyns, p. 352. Yarrell’s Br. 
F., vol. 1, p. 90. Having had an opportunity of inspecting 
a Specimen of this Fish in company with my friend Mr. 
Yarrell, I am able to refer with confidence to two indivi- 
duals that were taken in Cornwall. The colours of the 
latter were far more splendid than those of the former, and 
it is to be remembered that the serrations of the gillcovers, 
as represented in Mr. Yarrell’s figure, disappear with age. 
SEA BREAMS. 
BECKER. Squints Pagrvs. Jenyns, p. 354. Yarrcll's Br. 
F., vol. 1, p. 102. Common in Summer and Autumn. 
SPANISH BREAM. N. Erythrinus. Jenyns, p. 355. Yar- 
rell’s Br. F., vol. 1, p. 104. In Summer, not common. I 
have also known it taken at Christmas. 
BREAM. S. Cenlrodontus. Jenyns, p. 356. Yarrell’s Br. 
F., vol. 1, p. 107. The young Fish of the year, being 
without the lateral spot, is termed a Chad. Abundant, but 
most so in Summer. I have known it with developed Roe 
at opposite seasons of the year. 
OLD WIFE. Cantharus Griseus. Jenyns, p. 358. Yar- 
rell’s Br. F., vol. 1, p. 114. Common in Summer and 
Autumn ; I have also seen it in Spring, but in a meagre 
condition. 
RAY’S BREAM. Brama Raii. Jenyns, p. 359. Yar- 
rell’s Br. F., vol. 1, p. 117. I have considered the kindred 
Fish referred to in the transactions of the Linnean Society, 
vol. 14, p. 78, as a different Species; but the sketch of 
its figure, having been presented to Mr. Bewick, the cele- 
brated engraver, cannot now be referred to. 
THE MACKAREL TRIBE. 
MACKA11EL. Scomber Scombrus. Jenyns, p. 300. Yar- 
rell's Br. F., vol. I, p. 121. This Fish can scarcely be said 
to disappear from the Cornish Coast through the year ; but 
according to the observations which I have made for a few 
years, the males precede the females in their migrations in 
Spring: thus in 1834, March 24, out of 8 taken indiscrimi- 
nately, 7 were males ; on the 28th, of 8, 6 were males ; 
April 1st, of 4, 3 were males. In 1835, March 25, from a 
capture of 7,000, 17 out of 20 were males. In 1836, April
