Vol. XVI, pp. 129-132 November 12, 1903 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON A NEW SPECIES OF LARGE IGUANA FROM THE BAHAMA ISLANDS. BY LEONHARD STEJNEGEK, [By permission of the Secretary of the Smithsonian Institution.] Mr. J. H. Riley, of the United States National Museum, while attached to the Bahama Expedition of the Baltimore Geo-graphical Society, during the summer of 1903, collected a goad series of a large iguana belonging to the genus Cyclura on Watlings Island. He also secured a fine specimen of Cyclura bceolopha Cope on Andros Island, the type locality of this well-defined species. Two specimens collected by Mr, William Palmer in 1900 on the Isle of Pines, which I have regarded as typical of Cyclura cyclura, have furnished material for com-parison, with the result that the Watlings Island specimens are here described as a new species. It will be noted that a large ip-uana from Cat Island has been recorded under the name of the Cuban species (Cope, Proc. U. S, Nat. Mus., 1887, p. 43V), but in view of the close proximity of Cat Island to Watlings, it is probably nearer to the iguana described below, if not actually identical with it, than to the form inhabiting Cuba. The third species peculiar to the Bahamas is Cyclura carinata from Turk's Island, the most peculiar of them all. 35— PROC. BIOL. SOC. WASH. VOL. XVI, 1903. (129}
