148 Recently published Ornithological Works. 
We trust that tliis useful piece of work, once started, may- 
be brought to a speedy conclusion. No reason is given for 
the long delay of ten years which has taken place since the 
MS. was prepared. 
9. Finsch on the Birds of the Sildwest Islands. 
[Systematisclie UebersicLt der Vogel der Siidwest-Insein von T)r. O. 
Finsch. Notes Leyden Miis. xxii. pp. 225-309.] 
The ^' Sildwest ^' are a chain of volcanic islands in the 
Banda Sea, some 27 in number, Avhich extend eastwards 
from Timor to the Tenimber Islands. After an elaborate 
disquisition on what has been already done with regard to 
ornithology in this group by the collectors and naturalists 
of Holland, Germany, and England, Dr. Finsch calls special 
attention to the large collections recently made there for the 
Leyden Museum by Karl Schadler, who had previously- 
worked in New Guinea and Amboina. Some of these have 
already been described (see Notes Leyd. Mus. xx. p. 129), 
but their interest is such that Dr. Finsch has been induced 
to put together a complete account of them, to which are 
added references to all the previous authorities on the 
subject. We have thus before us an excellent memoir on the 
Ornis of this interesting island-group, which, so far as it has 
yet been explored, is shown to be the home of 123 species. 
Of these, 21 are peculiar to the group. One species 
[Rhipidura reichenowi) is now described as new, the other 
novelties having been already characterized. On three plates 
appended to this memoir some of the more remarkable 
species of the Siidwest group are depicted — Sphecotheres 
hypoleucus, Gerygone Hsserensis, G. wetterensis, Rhipidura 
reichenowi, Stigmatops notabilis, and Alopecoenas hoedti. 
The last-named is a very curious form of • Ground-Dove 
discovered by Hoedt in Wetter in 1866, and is known only 
from the typical pair at Leyden.
