discovered by Strickland, three years ago, in Zante, one of the Ioni- 
an islands. It belongs to that division of the Salicarig, in which 
the tail is but slightly rounded, and the colouring sombre and uni- 
form. Probably destined to form, with other nearly-allied species, a 
new genus. JVidification: not mentioned. One figure.
