248 BIRDS OF TUNISIA 



killed by one of my father's " cacciatori," and its skin was prepared 

 and preserved in our house until a few years ago. 



" I am unaware of any Francolin having been subsequently obtained 

 on the estate, as recorded by Doderlein, but this is quite possible." 



Francolimis bicalcaratus, the Double-spurred Francolin, appears 

 to occur on the west coast of Marocco as far north as Rabat, and is 

 said to be not uncommon in those districts, living examples of the bird 

 being sometimes sent from Mogador to England. 



CACCABIS PETROSA SPATZI (Reichenow). 

 DESERT BARBARY PARTRIDGE.

 Caccabis petrosa spatzi, Erlanger, J. f. 0. 1900, p. 27. 



Description. — Adult male, spring, from Meretba, South Tunisia. 



Differs from C. petrosa in its paler and more sandy coloration. 



Adult female resembles the male, but is rather smaller and has no spurs. 



The Barbary Partridge found in the more desert districts south of 

 the Atlas is somewhat paler in coloration than that met with in 

 Northern and North-central Tunisia, and has been distinguished by 

 Prof. Reichenow under the name of Caccabis spatzi (J. f. 0. 1895, p. 

 110). The difference from what may be considered typically coloured 

 examples is slight, and apparently, variable, but is perhaps just suffi- 

 ciently marked to call for subspecific separation. The two forms 

 naturally do not differ in their habits, notes, food and nidification.
