On the Lizards of the Genus Eremias, Section Boulengeria. By G. A. BOULENGER, F.R.S. [Received October 9, 1896.] Since the publication of F. Lataste's paper in the ' Annali' of the Genoa Museum, in 1885-in which he did m e the honour of connecting m y name with a division of the large genus Eremias, characterized by a divided lower nasal shield, ventral shields in straight series, and strongly compressed toes-our acquaintance with these Lizards has made very great progress. The numerous collections made within the last few years by Revoil, Ragazzi, Robeccbi, Ruspoli, Bottego, Donaldson Smith, and Lort Phillips in Abyssinia, Somaliland, and Gallaland, the headquarters of the group, have added greatly to our knowledge of them, not only in showing the doubtful species and variety previously described, and which I had placed in the synonymy of Eremias brennerl, Peters, to. be entitled to specific rank, but in bringing to light two more species, thus raising their number to five. Having lately received, through the kindness of the Marquis Doria and Dr. Gestro, large numbers of these Lizards, I have availed myself of the opportunity to recast detailed descriptions of all the species. The whole of the material I have worked from is either in the British Museum (specimens marked *) or in the Museo Civico of Genoa. |
