Guadeloupe. 2. O n some Specimens of Lizards in the Zoological Museum of Halle (Saale). By G. A. B O U L E N G E R. [Received March 6, 1889.] (Plate XV.) Having, at the request of Dr. O.

PLATYDACTYLUS ALBOMACULATUS, Giebel, Zeitschr. ges. Naturw. xvii. 1861, p. 59, from Banka, = Gecko stentor, Cantor. 3. PLATYDACTYLUS BURMEISTERI, id. ibid., from the same locality, = G. monarchus, Schleg. 4. PLATYDACTYLUS DEISSNERI, id. ibid. p. 60, from the same locality, = G. monarchus, Schleg.
