M. de Betta has published a paper on the Italian species, in which the 
synonymy and description of three species and their varieties are given, 
viz. T. natrixj T. tessellatus and 2\ viperinus. As regards the second (which 
is the T. hydrus), the author was not acquainted with Peters’s remarks 
in Monatsber. Ak. Wiss. Berl. 1863, p. 370. The paper is instructive, inas- 
much as it contains critical references to some publications which are almost 
unknown or inaccessible to herpetologists not living in Italy. Atti Istit.
