146 Mr. J. H. Gumey's Notes on 



species in which there are no differentiating characteristics in 

 the corresponding females. 



Pldegcenas Johannes rests on a female collected by Lient. 

 Richards. On examining the specimens in the British 

 Museum and in the collection of Capt. Wardlaw-Ramsay, I 

 find that a mistake has been made with some of the British- 

 Museum specimens, and that a bird labelled P. Johanna ranst 

 belong to P. margaretha. Possibly, therefore, the Phlegcsnas 

 of the Solomons may be another species of which we have 

 not yet obtained the male. 



Though Mr. Ramsay gives Chalcophaps chrysochlora as 

 from the Solomons, based on a female specimen, yet I have 

 ventured to doubt the identification, believing that it will be 

 found to be G. stephani, which is the indigenous species of the 

 neighbouring islands.

 British Museum' hj R. Bowdler Sharpe (1874). By

I HAVE now to refer to the two species which constitute the 

 subgenus Eryihropus, and which seem to me to form a 

 distinct natural group intermediate between tlie true Kestrels 

 and the Hobbies. 



The two species of Erythropus are both of them gregarious 

 and migratory ; but their ordinary geographical ranges^ except 

 perhaps in South-west Africa, are very distinct. 



The western species, E. vespertinus, is an inhabitant, 

 during the summer months, of Europe and Western Asia, 

 arriving in the spring, and migrating in the autumn to Africa; 

 it has, however, been recorded as also nesting in Algeria^. 



]\Ir. Sharpe, in his summary of the habitat of this species, 



does not refer to its occurrence either in Northern Europe or 



in Asia ; but examples from Archangel are preserved in the 



British Museum (as noted by Mr. Sharpe in his list of the 



* Loche, Expl. cle I'Algerie, Ois., vol. i. p. 70.
