*Mr. J. A. <',. Rehn in his Monograph of the genus Otopterus, Proc. Acad. 

 Nat. Scien. Phil., 1904, p. 437 (erroneously called by him Macrotus'), makes 

 Dobson 's species a synonym of O. mexicanus, and retains O. bulleri as a race 

 of the last named. Dr. J. A. Allen, in a "Note on Mexican Species of Otop- 

 ti-rus," Hull. Am. Mus. Nat. Hist. N. Y., 1904, p. 235, after a careful examina- 

 tion, di-eides that O. bocourtianus is a good species, and that O. bulleri should 

 become a syipnivm of O. mexicanus. Here we have two diametrically opposed 

 opinions entertained by two naturalists working independently of each other, 

 and in view of the impasse thus created, it seems best to consider the two 

 MIS distinct species, as they have heretofore been by most investigators, 

 especially as the specimens in this Museum appear to sustain that view of 

 the case. Although not a matter of supreme importance, it will, however, 

 probably re<iuin-. al'ii-r the decisions mentioned above, a consensus of opin- 

 ions among inaiimialogists before the question at issue shall be satisfactorily 

 settled.
