their varieties. (Read October 17, 1817.) Transactions Amer. Philos. Society, New Series, 
vol. I, 4to, Philadelphia, 1818, pp. 383-394, pi. 12. (Contains the original figure and descrip- 
tions of two varieties of H. rafticttfidHS or Lake Sturgeon; describes H . 6rei)iros/ris for the first 
time, with three varieties, and A. maciilosus. A. oxyrhynchus Mitch, mentioned.) 
18. Monro, Alexander. The structure and physiology of fishes explained and compared with those 
of man and other animals. Polio, Edinburgh, mdcclxxxv. (A beautiful work, illustrated with 
copper plates, of which those numbered viii, ix*, and xl contain illustrations of the visceral 
anatomy of the Sturgeon, which have not been much improved upon since.) 
19. Mitciiill, Samuel L. The fishes of New York arranged and described. Transactions of the Lit- 
erary and Philosophical Society of New York, vol. i, 4to, New York, 1815, pp. 355-492, jils. i- 
VI. (It is assumed, pp. 461-462, that the Sturgeon of the Hudson River is the same as Acipen- 
ser stario of Europe. The A. oxyrhynchus is first mentioned on pp. 462, 463, and it is stated that 
it is seldom over 5 feet in length. This statement and extracts from a letter by a Mr. De 
Witt, quoted by Mitchill, render it almost certain that the oxyrhynchus of this first American 
ichthyologist was founded upon the young of the common species. 
20. Owen, Richard. On the Anatomy of the Vertebrates. Vol. i, Fishes and Reptiles, 8vo, London, 
1866. (Contains considerable information on the anatomy of the Sturgeon.)

ear of the Sturgeon is very accurately figured in this great work.)

ports from the laboratory of the Zoological Museum of the University of Moscow, 4to, tome 
III, third series, Moscow, 1887 (Russian). (Some of the new results recorded in the above are 
contained in the two xireceding papers by the same author. The outlines showing variations in 
the forms of the heads of the \ arious species of Sturgeons found in Russian waters and the care- 
fully prepared tables of measurements are doubtless an important contribution to the natural 
history of these fishes ; but, unfortunately, the language in which the work is printed makes it 
inaccessible to naturalists and students speaking other languages.)
