The intei'est of the relationship of this Madagascar Bat to 

 pui-ely American groups is obvious, as adding one more to the 

 forms of that island which show the same affinity. 



But the alliance of the Myzopodidae to either the Natalid^e 

 or the Mormoopidse is by no means close, and there can be no 

 question that the Family is quite a distinct one. As a diagnostic 

 point, the coalescence of the tragus with the ear-conch is note- 

 worthy, for almost every Family of Chiroptera can be diagnosed 

 by the development and structure of this organ, and its unique 

 condition in Myzopoda is an index to the special peculiarity of 

 the group. 



Still more interesting will it be, as bearing on the question of 

 a southern connection between the faunas of the Old and ISTew 

 "Worlds, if the New Zealand Mystacops should prove to be a 

 member of the same series of forms. Its three- jointed middle 

 finger and the general structure of its skull and dentition point 

 in this direction, while its exserted tail and warty lower lip 

 suggest the Mormoopidse quite as much as the Emballonuridae, to 

 which it has been usually referred. Pending the publication of 

 Mr. Miller's researches on the classification of Bats, however, I 

 do not wish to do more than suggest a possibility that Mystacops, 

 like Myzopoda, may prove to have Ameiican affinities.
