and has given me the following account of his investigations 
and their results : — 
“Those specimens are a very important acquisition for 
American ichthyology as far as the study of species is con- 
cerned, and I have been enabled to investigate more closely 
the history of what is recorded under the name of ‘two spined 
Stickleback’ (G. biaculeatus.) 
* John Reynold Forster published, in 1771, * A Catalogue 
of the Animals'of North America, &c.,’ in which we find a 
two spined Stickleback, without any special indication of the 
locality whence it came. 
* In 1792, Pennant, in his * Arctic Zoólogy also records a 
two spined Stickleback on the authority of Forster, and men- 
tions New York as the place where specimens were obtained. 
* In 1803 appeared, * Shaw's General Zoology, in which 
the two spined Stickleback is cited on the authority of Pen- 
nant, the author not having seen the species; yet he gives 
the systematic name of biaculeatus, which was not hitherto 
one. 
“In 1815 Mitchill found the two spined Stickleback (G. 
biaculeatus) in the salt waters about New York, and gave a 
figure of it. There is no real description, and the figure, 
though perhaps good at that time, is very deficierit to-day. 
The author says that this seems to be the species d 
by Shaw. But Shaw himself had not seen it and cites Pen- 
nant, who does not describe it, mentioning it indeed only on 
the authority of Forster. 
“In 1829 was published the fourth volume of Cuvier and 
Valenciennes’s ‘ Histoire Naturelle des Poissons,’ where it is 
stated that a two spined Stickleback had been sent to Cuvier 
from Newfoundland. The description given in that work is 
very short, and insufficient to decide the species had we not 
specimens in our hands. Cuvier thought it to be the species 
figured by Mitchill, and probably, he says, ‘the one mentioned 
under the same name by Pennant and Shaw.’ 
“In 1836 that fish reappears in Dr. Richardson’s ‘ Fauna
