INDIAN CYPRINIDZ. 223 
food, I found, as might be expected, the greatest development of intestinal 
canal; in these the mouth is invariably either horizontal or directed down- 
wards, as in the Cirrhins; all such types I have included under the head of 
Peonomine or herbivorous Carps, of which the Gudgeons and Gonorhynchs 
are the most remarkable. 
5. In the last mentioned genera the mouth is situated completely under 
the head, and is constructed in the Gudgeons for bruising soft vegetable 
“Of birds, I observed about sixty species of Falconide, about 150 Insessores, and about 74 
Gralle, including many rare Tantalide, and the species of Czconza recently described as C. cristata, 
which appears to have been named nearly 30 years ago by Buchanan Ardea crinita ; all which, in 
addition to the fishes, are drawn in duplicate, thus amounting to about 900 drawings.” Although 
Buchanan was professedly a botanist, his researches appear to have extended to all branches of 
natural history except entomology. His volumes on Gangetic Fishes, published at his own expense, 
under the disadvantage of being deprived of the greater part of his figures, are the only part of his 
zoological labours that are known, yet his inquiries in other branches of zoology were equally exten- 
sive, and equally intitled to publicity. It now appears that two quarto volumes of MSS. written with 
his usual erudition, have been retained in the Library of the Botanic Garden since 1815, while every 
periodical that has since appeared deprived him of some portion of those claims to priority which his 
papers ought to have secured to him had they been placed in proper hands, or deposited in an institu- 
tion where their existence could have been known or appreciated. 
Had such an injury to the advancement of information anid from an oversight in an ordinary 
public office, the circumstance would excite less surprise ; but that the works of a naturalist should 
be so treated in a public Institution expressly intended for the promotion of science, is so 
unaccountable to me, that I cannot presume to express an opinion on the subject. But as the case 
stands, perhaps the best remedy that can now be applied in justice to Buchanan, as well as to 
others who are still engaged in scientific pursuits, would be to give a complete edition of his labours, 
botanical and zoological, to the public, at the same time it is right to say that no atonement can now 
make amends for the injury that has been inflicted on Buchanan as a naturalist, or for the time that 
has been lost in allowing others to go over unnecessarily the ground which he investigated, instead of 
beginning where he left off.
