In addition to these I have examined a female 

 and a huge bill from the Gambia, and a male from 

 Museum, the latter with black wings, but tlie back is steel black, not metallic green 

 or purple. Further material will probably prove these to belong to a new sub- 

 species of magnificens. 



There is also in the British Museum a i Frigate Bird from the Hume 

 collection, which is labelled as coming from the Malay Peninsula. This specimen 

 IS indistinguishable from the Ascension Island males. It is either a stray bird blown 

 out of its course or the label has been erroneously transferred. 



Mr. Mathews' contention that Fregata minor ridgwayi breeds only on Culpepper 

 and Wonmaa Island, while magnificens occurs only on the other islands, is disproved 

 by Beck's photographs (California Academy), which show both species breeding on 

 Hood Island.
