GENERAL NOTES. 



Note on the name Rhopocichla. 



Rhopocichla was first used by Gates in 1889 (Fauna Brit. India, Birds, 

 I, 159) for an Indian Timeline bird. Two years later Dr. Allen em 

 ployed the same term (Bull. Am. Mus. Nat. Hist., Ill, 199, 1891) for 

 a South American Ant Thrush. As the use of the same name in two 

 families of birds is liable to lead to some confusion it is proposed to re 

 place Dr. Allen's Rhopocichla by Rhopornis (type Myiothera ardesiaca 

 Wied). Charles W. Richmond. 



The technical names of two Dogbanes from the 

 District of Columbia. 



In his recently published Manual of the Flora of the Northern States 

 and Canada, Dr. N. L. Britton transfers the name Apocynum medium 

 Greene to the Dogbane which, in my paper on the species occurring in 

 the District of Columbia,* I described as A. speciosum. For the Apocy 

 num medium as there denned, he proposes the new name A. milleri. 

 Beyond the brief citation of synonyms no reason is given for these alter 

 ations; and after a careful examination of the facts I am forced to regard 

 the change as quite unwarranted. 



At the time of my revision of the species Professor Greene informed 

 me that he had based the name medium on a plant growing at a well- 

 known locality in Brookland, D. C. At this station there is found only 

 one species of Apocynum, living and fresh specimens of which furnished 

 the material for my description. Since the publication of Doctor
