assistants have accomplished a most meritorious piece of 

 work, of Avhich Mr. Ridgway now gives us the results. 



The new species described are : — Nesomimus macdonaldi, 

 from Hood I. ; N. personatus, from Abingdon I. ; Geospiza 

 conirostris and G. media, from Hood I. ; Cactornis brevi- 

 rostris, from Chatham I. ; C. hypoleuca (if not C. pallida, 

 Scl. et Salv.), from James I. ; Camarhynchus townsendi, from 

 Charles I.; C. pauper, from Charles I.; Pyocephalus mini- 

 mus, from Chatham I. Besides these the form of Pcecilo- 

 nelta bahamensis of the Galapagos is separated as P. galapa- 

 goensis. The Galapagan Mimi are constituted a new genus, 

 Nesomimus, distinguished by their longer and more com- 

 pressed bill and longer tarsus. Two specimens of the rare 

 Gull Creagrus furcatus, an adult male and an adult female in 

 perfect summer plumage, were obtained on Dalrymple Rock, 

 Chatham I., and are fully described by Mr. Ridgway. A 

 table, showing the different islands of the group in which 

 the 69 species now known to occur in the Galapagos have 

 been found, is added, and is followed by lists of the species 

 met with on each island. " It is very evident," says Mr. 

 Ridgway in his concluding remarks, with which we quite agree, 

 " that the avifauna of the Galapagos is by no means yet 

 exhausted as a field for promising research in the problem of 

 derivative origin of species." Albemarle Island, the largest 

 of the group, is still almost untouched, two others (Wen- 

 man and Culpepper) have not been explored at all, whilst 

 " it can safely be said that on none of the islands has any- 

 thing like a thorough investigation yet been made."

Seven years are past since the third and last volume of Count 

 Salvador's ' Ornitologia della Papuasia e delle Molucche ' 

 was published. The author now proposes to issue a supple- 

 ment to his former excellent piece of work, in order to bring 

 our knowledge of the subject up to the present period. Of
