may appear scarcely credible, yet, I have noticed, in other 

 species of birds, during the breeding season, a temporary as- 

 sumption of habits much more incongruous and unaccounta- 

 ble than the one abovementioned. 



Alterations, such as have just been suggested, even when 

 based upon incontrovertible evidence, are attended, I am 

 aware, with serious inconveniences. Independently of an ac- 

 cumulation of synonymes, from which the student turns away 

 in disgust, persons who have discovered, accurately described, 

 and, probably, with no little toil, obtained almost all the infor- 

 mation which science possesses of certain species, are thus 

 liable to be deprived, in a great measure, of the credit justly 

 due them, by some other person, whose sole claim to notice 

 may consist in the mere rectification of some error respecting 

 the position of the objects. 



The preceding information has not been communicated 

 from any desire of connecting a name with a species which 

 has been long, though very imperfectly, known ; but from a 

 sense of the importance of accuracy of arrangement. Let the 

 real position of the bird be acknowledged, and the person, by 

 whom the alteration has been suggested, will be perfectly sat- 

 isfied, though his name should never be mentioned in connec- 

 tion with the species. Those who love science, for its own 

 sake, will feel but little regret, provided its progress be ac- 

 celerated, should their claims to notice be occasionally over- 

 looked, even in cases which are really of importance.

The peculiar characters of the most common slug of our

 Carolinensis, induced Dr. Binney, in his memoir on the
