notes by the members of the expedition which add much to our knowledge 

 of the habits of the birds of this wonderful country. 



Many new forms have already been described from these collections, but 

 others, recognized as the critical study of the material progressed, are here 

 described for the first time. These are: Cicinnurus regius claudii (p. 16) 

 Lophorhina superba fetninina (p. 27); Ptilotis salvadorii utakwensis (p. 71) 

 Pachycephala soror klossi (p. 88); Lalage karu microrhyncha (p. 118) 

 and Pseudogerygone conspicillata mimikae (p. 168). New forms described 

 from other parts of New Guinea or elsewhere are as follows: Diphyllodes 

 rothschildi (p. 24), Salawatti; Pachycephala soror bartoni (p. 88), British 

 New Guinea; Rhipidura harterti (p. 149), Rendova, Solomon Isls.; Poecilo- 

 dryas brachyura duniasi (p. 162), Northern New Guinea; Microeca grisei- 

 ceps bartoni (p. 174), Mt. Manacao; Alcyone richardsi aolae (p. 206), 

 Aola, Guadalcanar, Solomon Isls.; A. r. bougainvillei (p. 207), Bougainville, 

 Solomon Isls. 



Mr. Ogilvie-Grant has evidently spared no pains to make his report as 

 full and accurate as possible and he has succeeded in producing one of the 

 most valuable contributions to the ornithology of New Guinea that has 

 yet appeared. With so many points of excellence to its credit it is regret- 

 table to find the old custom perpetuated of designating two types — a male 

 and female. In case these should eventually prove to belong to different 

 forms — and such things have occurred ! — we immediately have an 

 opportunity for a nomenclatural entanglement, which would have been 

 entirely avoided by designating but one type specimen. — W. S. 



Chapin on New Birds from the Belgian Congo. » — Continuing the 

 critical study of the collection obtained by the American Museum Congo 

 Expedition, Mr. Chapin describes four new species. These are a Starling, 

 Stilbopsar leucothorax (p. 23), from the Ituri District; Paludipasser uelensis 

 (p. 24), from the Upper Uele District, a curious Weaver Finch, apparently 

 congeneric with Mr. S. A. Neave's Paludipasser locustella from Lake Bang- 

 weolo; another Weaver, Malimbus flavipes, (p. 27), Ituri District and a 

 warbler, Bradypterus carpalis (p. 27), from the papyrus swamps of the 

 Upper Uele. Drawings of head and feet accompany the excellent descrip- 

 tions and a few remarks on habits are added, forming a welcome relief 

 from the all too prevalent meagre diagnoses which characterize many 

 present day systematic papers. — W. S.
