The forearm measures about 62 of the skull is necessary in order to distinguish thisbat with certainty from Artibeus planirostris planirostris. It lacksthe tiny third upper molar present at the posterior end of the seriesin the latter Fig. 16.—Artibeus jamaicensis 203082, U. S. Nat. Mus. About nat. size. Dr. Knud Andersen (1908) in a revision of the genus states(p. 266) that to prevent wrong identification it is important toemphasize that Central America is inhabited by two races, whichought not to be (but hitherto have always been) confused, viz., thesmaller (truly indigenous) A. j. jamaicensis and the larger A. (an immigrant from south). In similar language hereiterates (p. 278) that in Central America and S. Mexico A. meets the considerably smaller A. j. jamaicensis. Thereis no doubt whatever that the latter race is the truly indigenous formin the region north of Panama, and that A. j. palmarum is a lateintruder from the south into the same region. Dr. Andersenspositive assertions, made after a careful study of the group, shouldbe given considerable weight; but since the forms as recognized byhim appear to be characterized by average
