BY ARTHUR LOVERIDGE. In their recently published paper on "The Land Vertebrates of Pemba, Zanzibar, and Mafia," Moreau and Pakenham (1940, Proc. Zool. Soc. London, p. 107) invite attention to a suggestion of Parker's that the Phelsuma of Pemba Island may be an endemic form of madagsacariensis Gray, of which other color forms occur on Aldabra and the Seychelle Islands. With the object of settling the point, Mr. R. H. W. Pakenham collected a series of these geckos, which, under normal conditions, would have been submitted to Mr. H. W. Parker. The latter, however, is serving his country, and so I take pleasure in naming the new insular race after him; paratypes of this and the other races described below, will be reserved for the British Museum. Undoubtedly Pemba Island has been separated from the mainland sufficiently long to permit of the stabilization of certain color-pattern forms, and I now take the opportunity of stating that Mahuya maculila-bris albotaeniata Boettger, of which Mr. Pakenham has now submitted a good series from various parts of the island, is a perfectly valid race, though 1 synonymized it in 1928. Phelsuma madagascariensis parkeri, subsp. nov. Type. — Museum of Comparative Zoology, No. 46,086, a gravid 9 from Kinowe, Pemba Island, collected by R. H. W. Pakenham, December 3, 1940. Parnhjpes. — Museum of Comparative Zoology, Nos. 46,087-46,092, being four males, a female, and a young gecko, from near Kinazini, Pemba Island, collected by R. H. W. Pakenham, September 9, 1940. Diagnosis. — Agrees with madagascariensis Gray in proportions and scale counts, but differs in color pattern. Description. — (Paratype variations in parenthesis.) Snout (1% to) 2 times as long as the di.stance between the eye and the ear-opening, vertical diameter of the latter C^ of, or) equal to, that of the former; rostral without (rarely with) a median cleft above; centre of nostril above the 30— Pboc.
