Mr. R. B. Sharpens Catalogue 0/ Accipitres. 437 



Mr. Swinhoe in 'The Ibis' for 1875, p. 448. This was 

 based on a skin which is now in Mr. Seebohm's possession, 

 and which he has been so good as to allow me to examine. 

 This specimen is merely an adult male of the Common Hobby 

 {Hypotriorchis subbuteo), and is not referable to any phase 

 of Erythropus amurensis. 



I also mentioned {supra, p. 158) that I had not seen any 

 specimen of Hypotriorchis concolor which corresponded with 

 Mr. Sharpens statement that " very old examples " of that 

 species *' become leaden black. '^ This statement I may now 

 modify, as, during a recent visit to the British Museum, I 

 there saw a skin of this species from the province of Betsileo, 

 in Madagascar, which appeared to me to be decidedly mela- 

 nistic, the entire plumage being dark brown slightly tinged 

 with grey on the lower back and on the upper surface of the 

 tail, and greatly resembling in colour the fuliginous plumage 

 of H. eleonorce. This specimen seems, however, not to be a 

 very old bird, as the inner webs of the lateral rectrices are 

 perceptibly cross-barred with bands of a darker brown. 



I have also, since my last paper, examined the female 

 Falcon shot by Mr. Blanford in the Anseba valley, Abys- 

 sinia, and to which I referred [supra, p. 308) ; and having 

 tested the measurements given by me in a note at that page, 

 I find them correct, except that of the middle toe s. u., 

 which I now make 1*90 instead of 2"20. This Falcon is 

 hardly sufficiently adult to admit of a thoroughly satisfactory 

 identification ; but I incline to the opinion that it is referable 

 to F. punicus rather than to the southern F. minor. 



Of the latter species I measured, at the British Museum, 

 a South-African male, which I had not previously examined, 

 w^ith the following results — wing 10*85, tarsus 1'70, middle 

 toe s. u. 1"80. On remeasuring the South- African female in 

 the British Museum, to which I have referred at p. 313, I 

 find the length of the tarsus is not 2'00, as there given, but 

 1-80. 



I have given, at p. 312, the measurements of a female of 

 F. barbarus from Granada, which is preserved in the British 

 Museum ; and I have now had the opportunity of measuring a
