ME. G-. A. BOULENGEE ON THE 



Italian specimens ; whilst in only one case ( d from Pelagosa Grande) have I observed 

 the rostral entering the nostril in the specimens referred to the var. ser^a. Size 

 and markings are no safe guides to the determination any more than in those parts 

 of Italy (the Roman province) where the two forms seem to intermingle. I will only 

 observe that the subvars. a, b,f, of Werner* are referable to the var. camjpestris, 

 d 8c e to the var. serpa, whilst c embraces both. 



Var. CAMPESTEIS.

t Non L. merremii B.isso ( = L. muralis typ.). L. merremii Fitzinger is a nomen nudum which has been 

 used hy Erber (Verh. zool.-bot. Ges. Wien, xvii. 1867, p. 855), Bedriaga, Werner, and others for this variety 

 as well as for fclie va,Ts.Jiumana and serjja. L. merremii Sohinz (Eur. Faun. ii. p. 25, 1846) is no doubt based 

 on a young L. viridis, var. major.
