552 Recently published Ornithological Works. [Ibis, 
Part xv. is occupied with the Alcse, the Alectorides (with 
families Otidse, Gruidse, and Rallidse), the Hemipodii 
or Turnices, and the Galli. This leaves only the rest of 
the Galli and the Ostrich to finish, but we understand a 
formidable supplement and indexes are to follow to com¬ 
plete the work and bring it up to date. 
We have found a few points which appear to require 
comment. The type of Podiceps is stated to be P. fluviatilis. 
This must surely be a slip of the pen for P. cristatus ; 
moreover, the Little Grebe is called P. ruficollis in the main 
text and not P. fluviatilis. We note also that the genus Morus 
is admitted for the Solan Goose. Although the generic name 
of the Cranes is rightly given as Megalornis , the family 
itself is named Gruidse; surely according to nomenclatural 
rules the family name should be taken from the earliest- 
described genus within its limits. Anyhow, as Grus has 
been shown to be a synonym of Psophia , it seems illogical 
to use the term Gruidse as a family name. 
It will be, perhaps, useful to mention the new forms 
described in the three parts now under notice. They are 
as follows :— Podiceps ruficollis japonicus, p. 1455 ; (Enopo- 
pelia tranquebarica murmensis from the Himalayas, p. 1499; 
Cursorius gallicus exul from the Cape Verde Islands, 
p. 1526; Sterna maxima albididorsatis from west African 
coasts, p. 1698 ; Gallinula chloropus seychellarum , p. 1843; 
and Lagopus mutus pyrenaicus, p. 1869. 
With regard to the Seychelle Moorhen, a race from the 
island of St. Denys to the north of the main group of 
the Seychelles appears to have been named by the late 
Prof. Newton (Diet. Bds. p. 590, footnote) Gallinula 
dionysiana, though the description is not very adequate 
and the diagnostic character relied on is the extreme 
reduction of the size of the wings. This does not appear 
to be the case with the bird described by Dr. Hartert, but 
comparison of the two forms would be of interest.
