The first of these papers, which is chiefly in Japanese 

 though the names and descriptions are also in English, con- 

 tains an account of a collection of birds made by Mr. Teraoka 

 from the island groups of the western Pacific, formerly 

 belonging to Germany but now occupied by Japan. These 

 are the Marianne, Pelew, Caroline, and Marshall groups. 

 A number of species are listed and two new forms 

 described — Halcyon chloris teraohai from the Pelew Islands, 

 and Collocalia fucifacja rukensis from Ruk Island in the 

 Caroline group. Both are figured in colour. 



The second paper (wholly in English) deals with a col- 

 lection made by Mr. S. Tsuchiza on the Red river in French 

 Tonkin. It contains representatives of 130 species. There 

 are no field-notes, but one new species is described, Gecinus 

 rubripectus, and some taxonomic notes are given in the case 

 of the more interesting forms. 



The collection described in the third paper was to a large 

 extent made by Mr. Kuroda himself during a visit to 

 Formosa in 1916. To the number of species and subspecies 

 given by Mr. Uchida our author has added 30, bringing 

 the total number of forms in the Formosan avifauna to 331. 

 One of these is a new Bullfinch allied to Pyrrhula nipalensis 

 of the Himalayas, but distinguished by the white areas in 

 some of the tail-feathers ; it is named P. uchidai. There are 

 interesting field-notes and critical remarks on many of the 

 other species obtained, among which are two pairs of the fine
