No. 4. — The Anoles. II. The Mainland Species from Mexico Southward By Thomas Barbour Introduction This list is in no sense final. The author is under no delusions as to its unsatisfactory nature. The final arrangement of Anolis, especially the indicating of phyla, of "Formen kreisen," the probable division of this unwieldy genus into several genera and a complete list of the species will not be written for many, many years. Nevertheless our knowledge of Anolis has advanced enormously since the appearance of the second volume of the Catalogue of Lizards in the British Mu-seum from the pen of Dr. G. A. Boulenger in 1885, This list then is simply an attempt to set forth our present state of knowledge. I list those forms of which the validity and status is well established and all others concerning which there is no information to counter-indicate their validity. The synonymy is not complete nor intended so to be. It contains the important references since the work of Boulenger which I have just mentioned. For convenience, however, the original description is given and the type locality is likewise re-corded as well as the place where the types are preserved. The last information, however, is not complete for some cotypes have no doubt been distributed of which I know not, while in other cases they appear to be lost. Where species have been originally proposed under some generic name other than Anolis this name appears within parentheses. Boulenger's Catalogue of 1885 gives full details concerning this synonymy of years ago and this stands except where his conclu-sions are counter-indicated herein. This little paper is the complement to one which I published in the Bulletin of the Museum of Comparative Zoology, Vol. 70, 1930, p. 103-144, in which I listed all of the Insular Anoles known to that year. I have added occasional notes as to seasonal appearance or abun-dance where I have information worth recording. It is a pleasure to record the assistance which I have had from my old friend and student Professor E. R. Dunn, who has read the whole manuscript and added many valuable notes and suggestions, as well as from my other friends, Mrs. Frederick M. Gaige, Miss Doris Cochran, and needless to say I have never written a paper which
