* According to Camerano (Mon. Saur. Ital. p. 64) the lower parts may be of a “rosso deciso” in females. 
‘’he colour of the lower parts is of very little importance for the definition of varieties (see Tr. 1905, p. 383, 
and pl. xxii.), and is not always a guide for the distinction of the sexes, as the so-called var. rubriventris 
of the typical form may be found in both sexes (Bedriaga, Bull. Soc. Zool. France, 1879, p. 215). Kammerer 
is mistaken when he says of the female (Arch. Entwickm. xxix. 1910, p. 459), “ Ventralseite des normalen.
