178 MR. G. A. BOULENGER ON THE 
Italian specimens ; whilst in only one case (¢ from Pelagosa Grande) have I observed 
the rostral entering the nostril in the specimens referred to the var. serpa. 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, 0, f, of Werner* are referable to the var. campestris, 
d & e to the var. serpa, whilst ¢ embraces both.

+ Non ZL. merremii Risso (=L. muralis typ.). L. merremii Fitzinger is a nomen nudum which has been 
used by Erber (Verh, zool.-bot. Ges. Wien, xvii. 1867, p. 855), Bedriaga, Werner, and others for this variety 
as well as for the vars. fiwmana and serpa. L. merremii Schinz (Eur. Faun. ii. p. 25, 1846) is no doubt based 
on a young L, viridis, var. major.
