This species presents two extreme forms, graduating into each 
other—the typical (L. boskiana of Daudin and Audouin) with 
smaller dorsal scales, hitherto found only in Egypt; and the var. 
asper, Aud., with larger scales, having a wide geographical range. 
Through the typical form this species is connected with A. syriacus, 
which leads to A. schreiberi, A. micropholis, and A. savignyt. 
Besides, the transition from A. boskianus to A. cantoris is so com- 
plete as to render the naming of certain specimens almost arbitrary.

Snout usually longer than in A. boskianus, acutely pointed; in 
consequence, the frontonasal and preefrontal shields more elongate.
