nipalensis Hodgson).' It may be replaced by Dyspetornis, from 
dvenetys, difficilis, and ¢pytc, avis. The type and only species, 
Hydrornis natator Milne-Edwards, should therefore now be called: 
Dyspetornis natator (Milne-Edwards). 
NENIA Boie 
The name Nenia Boie® is untenable by reason of Nenia Stephens,‘ 
employed for a genus of Lepidoptera. The next available name is 
apparently Larosterna Blyth;* but the book in which this was pub- 
lished, though bearing on its title page the date 1849, contains in- 
ternal evidence to show that it did not appear until at least 1852. 
This gives priority to /nca Jardine,’ which has the same species, 
Sterna inca Lesson, as its type. The only species of this group, 
therefore, now becomes: 
Inca inca (Lesson). 
GNATHOSITTACA Cabanis 
An earlier name for Gnathosittaca Cabanis? which is based on 
Gnathosittaca heinet Cabanis (== Conurus icterotis Massena and 
Souancé) is found in Ognorhynchus Gray,* type Conurus icterotis 
Massena and Souancé. 
The sole species is: 
Ognorhynchus icterotis (Massena and Souancé). 
DASYPTILUS Wagler 
The generic name commonly applied to Psittacus pecquetu Lesson 
is Dasyptilus Wagler ;° but this is, however, antedated by Psittrichas 
Lesson,'°used for the same bird. 
This species should therefore stand as: 
Psittrichas pecquetw (Lesson.)
