7. Meriila, "Leach, 1816" (type, Turdus merula, Linn.)- 



The ]iroi)pr fjeneric division of the typical thrushes is a matter of considerable difficulty. 

 Of the North American generic groups, Hylocichla and Henperocichla of Baird are suffici- 

 ently isolated, the latter being represented by a single species only, the former by all the 

 smaller spotted species, besides the Song Thrush (Turdus musicus, Linn.) of Europe. I find 

 no American species agreeing at all closely -with Turdus viscivorus (the type of Turdus) in 

 form ; and a generic divisiou based wholly or chiefly on coloration being out of the question, 

 I find no other alternative than to adopt for the Kobin ajid other American thrushes usually 

 referred to "Plancsticus' of Bonaparte (1804) the name Merula, Leach (181(i), there Ijciug no 

 essential difference in form between the tyjie of the latter. Tardus merula, l.iun. (Meritla 

 nigra, Leach) and our Kobin (T. migratorius, Linn.) ; while a number of the Neotropical 

 species exhibit the same sexual difference in coloration as T. merula. I would also refer to 

 Merula the following Old World forms: Turdus pilaris, Linn. (ty\)e ot Arceuthornls, Kaup, 

 1829), Turdus atrogularis, Temm. (type of Ciehloides, Kaup, 1829), Turdus torquatuf:, Linn, 

 (type of Thoraeocincla, Kcich., 1850), with perhaps some others.

*It is exceedingly doubtful whether Wilsonia, Bp., should displace Myiodioctes, Aud. Bonaparte's 

 name occurs first in a mere list, is used only as a heading for a subgeneric groiiji, and is unaccom- 

 panied either by a diagnosis or an indicatiou of type. Audubon, however, only a year later, in desig- 

 nating ihe same group of birds by the new generic term Myiodioctes, gave au excellent diagnosis of the 

 generic charnct'ers. It appears to us that the sRght difierence of date in favor of Bonaparte's name is 

 greatly overbalanced by the pains which Audubon took to duly characterize his genus, thus conform- 

 ing to the recjuirements of nomenolatural laws, which Bonapaite tViiled to do.
