 This species presents two extreme forms, graduating into each 

 other^ — the typical {L. hosHana of Daudin and Audouin) with 

 smaller dorsal scales, hitherto found only in Egj'pt ; and the var. 

 asper, Aud., with larger scales, having a wide geographical range. 

 Through the typical form this species is connected with A. syriams, 

 which leads to A. schreiberi, A. microjpholis, and A. savignyi. 

 Besides, the transition from A. hoslcianus to A. cantoris is so com- 

 plete as to render ilie naming of certain specimens almost arbitrary.

 consequence, the frontonasal and prefrontal shields more elongate.
