islets of the south-west group in the great Eastern Archi- 

 pelago — contains examples of 70 species, which are now 

 catalogued, with explanatory notes. Four new subspecies 

 are denominated Ninox boobook cinnamomina, Muscicapula 

 hyperythra audacis, Orthnocichla subulata advena, and Pachy- 

 cephala melanura tepa. 



Dr. Hartert points out that the Ornis of Babber " differs 

 considerably from that of the more western islands," being 

 in many respects the same as, or closely allied to, that of the 

 Tenimber group.

[On the Birds of Luang. By Dr. Ernst Hartert. T. c. pp. 302-304.] 



On leaving Babber Mr. Kiihn's taxidermists visited the 

 islet of Luang, near Sermatta, of the same group, and 

 obtained examples of 41 species of birds, of which the names 

 are now recorded, accompanied by a few remarks. One 

 example of the Australian Grallina picata is among them, 

 shewing that this species occasionally strays far northwards. 



114. Hartert' s 'Miscellanea Ornithological 



[Miscellanea Ornithologica. Critical, Nomenclatorial, arid other Notes, 

 mostly on Paloearctic Birds and their Allies. By Ernst Hartert, Ph.D. 

 Part III. T. c. pp. 386-405.] 



Dr. Hartert continues his valuable notes (see ' Ibis/ 1905, 

 p. 123), and discourses on Anthoscopus, Panurus, Colceus, the 

 Palaearctic Muscicapidse, the African Pycnonoti, and the 

 Pahearctic forms of Lanius, Avhich last form one of the most 

 thorny problems in Ornithology. He criticizes Mr. Ogilvie- 

 Grant's treatment of the Lanii (Nov. Zool. ix. p. 449, 1902) 

 pretty severely, and utterly refuses to agree with many of his 

 conclusions. 



Dr. Hartert maintains that Lanius excubitor and the allied 

 form usually called Lanius major arc specifically inseparable. 

 " Both varieties occur in the same area, and both have been 

 found in the same nest. It is thus perfectly clear that 

 only one form of Grey Shrike inhabits Northern Europe,
