Dr. Van Oort is engaged in the praiseworthy task of 
forming a collection of the birds of Holland for the Leyden 
Museum. In this memoir he reports a year’s progress, 
during which he has acquired 675 skins. Among these there 
are examples of two species new to the Collection— Megalestris 
skua and Serinus serinus. Fourteen other important species 
are stated to have received additional representatives.

A “ subspecies” of Psephotus chrysopterygius , described 
as P. c. blaauwi, is based on a specimen received from 
Mr. Blaauw, who has other living examples of the same 
form in his Aviaries. They are believed to have come from 
Port Darwin, North Australia.

This interesting memoir gives us an account of the col¬ 
lection of birds recently made by Mr. Koch and Dr. H. 
A. Lorentz on the coast of southern and south-western New 
Guinea. In 1907, Dr. Lorentz obtained a good series of 
about 480 skins, principally at various stations on the Noord 
River, which was ascended to a height of more than 2,500 
metres. He also visited Merauke, near the southern¬ 
most point of Dutch New Guinea. Both these localities are 
shown in Stanford’s map of New Guinea (Compendium of
