XXII. — On Straucli's Triton longipe?. 

 By G. A. Boulenger. 



In my revision of the newts, published in 1882'*, I expressed 

 the opinion that Straticii's Triton longipes f from Astrabad, 

 N. Persia, should probably be considered a variety of 

 Molge criatata^ agreeing with var. Karelinii, Strauch, except 

 in the more elongate digits. This view was endorsed shortly 

 afterwards by Camerano +, who referred some Italian speci- 

 mens (from tiie Gran Sasso) to subsp. longipes, not, however, 

 without some hesitation. I am now in a position, thanks to 

 the kindness of Dr. F. S. Monticelli, who sent me numerous 

 specimens of M. cristata from near Naples, to state that 

 T. longipes represents merely an individual variation Qi Mvlge 

 cristata, var. Karelinii. Among the Naples specimens there 

 is one, a male post nnptias, which is in every respect 

 referable to T. longipes ; its digits are extremely slender and 

 elongate, all the lingers except the first extending beyond the 

 snout when the lore limb is stretched forwards, and the 

 longest toe reaching the elbow when the limbs are pressed 

 against the body. As there exists in the same locality every 

 passage between such a specimen and a normal M. cristata,
