320 Notes on Mr. R B. Sharpe's (Catalogue of Aocipitres. 



dissection to be a female^, and is in my opinion an undoubted 

 specimen of F. punicus. It is marked U in my list of 

 examples of that species. The coloration of the upper surface 

 in this female much resembles that of the medium-coloured 

 males as regards intensity of tint ; the position of the rufous 

 on the nape is very much as in D, but it is less extended 

 upwards and is more mingled with slaty black ; the ground- 

 colour of the underparts is richly tinged with rufous, and 

 more so on the cheeks, throat, crop, breast, and flanks than in 

 any of the males that I have examined ; the feathers of the 

 crop exhibit conspicuous black shaft-marks, broadest on those 

 feathers which are nearest to the chest ; the underparts below 

 the crop are strongly cross-barred with black, except on the 

 under tail-coverts, where the transverse bars are faint, and on 

 the centre of the breast, where they are broken up into bar- 

 shaped spots. 



Mr. Salvin (/. c.) also mentions two Algerian Falcons which 

 were brought to England as nestlings by Canon Tristram, 

 and which I had for some time alive. One of these unfor- 

 tunately escaped. The other died in bad plumage; but its 

 skeleton is preserved in the Norwich Museum. On dissection 

 it proved to be a female ; and the measurements of the tarsus 

 and middle toe indicate that the specimen was likewise 

 referable to F. punicus. 



R, from Cape Spartel, much resembles U ; but it has more 

 rufous on the nape, where this colour may almost be said to 

 form a nuchal collar, though less regular and complete than 

 in F. barbarus. 



P, from Morocco (probably Mogador), died whilst changing 

 from immature to adult dress. It has to a considerable extent 

 attained the latter ; and so far as it has done so it much 

 resembles R. 



T, from Tangier, is very similar to R as regards the upper 

 surface and the amount of rufous on the nape ; but on the 

 underparts the rufous tints, though conspicuous, are paler, 

 and on the abdomen the cross bars are replaced by small and 

 somewhat faintly marked dark spots ; the crop is also entirely 

 destitute of dark shaft-marks.
