Lataste has distinguished three varieties, which do not seem to 

 me to deserve special denominations : the typical form (var. scutel- 

 Jata), of which measurements are given above, from Egypt and 

 Syria; a smaller variety, var. exigua, Lat. ( = inornata, Gray), 

 apparently restricted to the Sahara ; and var. diimerilii, M.-Edw., 

 from Senegambia.
