Saunders, Howard. On the Stercorariince or Skua Gulls. P. Z. S. 
1876, p. 317. 
A monograph of the genus Stercorarius, in which the complex syno- 
nymy of each species is fully discussed, and the range given. Several 
changes are made in names usually adopted, but Mr. Saunders gives 
good reasons for the conclusions he has come to on these points. One 
South American species, long ago alluded to by Bonaparte under the 
name of Lestris cMlensis, but since lost sight of, is here fully recognized.

. On the Sternince^ or Terns, with Descriptions of three new 
Species. Tom. cit. pp. 638-672. 
Five genera of SternincB are recognized, out of upwards of 30 that 
have at various times been proposed in this sub-family. The intri- 
cate synonymy of the Terns seems to have been successfully investi- 
gated by the author, who has been enabled to assign to their proper 
species most of the doubtful names that have haunted their nomencla- 
ture. As this has been achieved mainly by an examination of type and 
typical specimens, there is reason to hope that a considerable number 
of the author’s determinations in this paper will be final. {^Laridce.']

In this translation of De Filippi’s “ Viaggio,” Herr Schalow has added

Mr. Blanford’s papers published in the Ibis for 1874.
