THE OSPREY. 41 



suits of his work were published in an elaborate paper, by M. E. Oustalet 

 entitled "Les mammiferes et les oiseaux des iles Mariannes", in the 3rd Series 

 of Nouvelles Archives du Museum d'Histoire Naturelle de Paris"', Vols, vii 

 and viii. (1895-1896). 



In the mean time, wliile M. Oustalet was working up M. Marche's material, 

 two Japanese collectors wtie sent to the islands by Mr. Alan Ovvston of 

 Yokohama, at the request of Mr. Walter Rothschild of the Tring Museum. 

 They arrived in Guam in December, 1894, and remained until the following 

 winter. Among the birds sent home by them were three specimens of a Rail, 

 shot during the months of May, June and July, 1895, on the Island of Guam, 

 six years after M. Marche had collected the same species. This was described 

 by Mr. Rothschild as a new species, Ilpotaenid'm oiDstvni, and by M. Oustalet as 

 Hypotaenidia marchei. Mr. Rothschild's description was published in Vol. ii 

 of Novitates Zoologicae, the journal of zoology of the Tring Museum, in 1895. 

 During the latter part of the same year M. Oustalet's first paper on the 

 Marianne fauna appeared, but the second paper, in which the description of the 

 Jlijjwtaenidia was given, did not appear until the following year. Mr. 

 Oustalet's paper had probably been handed in for publication before the ap- 

 pearance of Rothschild's description, as he docs not refer to the latter. After 

 stating that the bird had been collected by Quoy and Gaimard, who wrongly 

 referred it to Ealfm j^^^iUpj^tm^is, and giving a description of it in which he 

 points out the peculiarities which distinguishe the birds collected by Marche 

 from that species, M. Oustalet says: "Je me crois done pleinement autoris^ a 

 les attribuer a une espece inedite que je designerai sous le nom (P Ili/jy/facni- 

 diamarchci'\ In 1898 Mr. Ernst Hartert published a paper "on the birds 

 of the Marianne Islands", in which he gives^a resume of all that was known 

 regarding the bird fauna of the group. He recognizes Mr. Rothschild's name 

 for the Hypotaenidia, and expresses doubt as to the occurrence of a distinct 

 species of Zosterops on the island of Saipan and of an Acrocephaius on Pagan 

 differing from the Guam species. 



The last collection made in the Mariannes was in the summer of 1900, by 

 Mr. Alvin Soale, of the Bernice Pauahi Bishop Museum of Honolulu. His 

 labors were confined to the Island of Guam. The Director's Report for 1900, 

 which has recently appeared, contains an acount of his "Mission to Guam," in 

 which he describes a new bittern, heretofore believed to be Ardetta sinensis 

 (Gmel.), besides a number of new fishes. As Mr. Scale makes me responsible 

 for the vernacular names cited by him, and as several inaccuracies occur 

 in them, as they appear in the report, I have ventured in the following list to 

 give them correctly. I have also added a few notes taken while in Guam, and 

 I refer to allied species occurring in Samoa. 



In comparing the reports of the various explorers and collectors who have
