HANKS to Dr. Giuseppe Zanandrea, Istituto di Anatomia Comparata della Universita di Bologna, we received two wellpreserved samples of Italian lampreys, one of which consists chiefly of transformed individuals and the other of ammocoetes. Careful study showed these specimens to be so different in comparison with Lampetra planeri (Bloch), obtained from various European countries, that I regard them as a distinct species. This new species is named in honor of Dr. G. Zanandrea, who made several interesting biometrical and biological studies of lampreys from northern Italy (Zanandrea, 1940a, 1940b, 1947, and 1951).
