Mr. O. Thomas on the Genua Cliirodeiuna. 187 



known to zoolo<^ist3 in connexion with tiic foundation of the 

 Trinidad Field Naturalists' Club, of which he is president. 



Again, in 1891 I had the opportunity of descnbin.:^* a 

 Stenodermatous bat, this time of the genus Ckiroderma itself. 

 That description was based on the Minas Geraes specimen 

 called in Dobson's Catalogue Ckiroderma villosum, Peters ; 

 and reasons were shown why it should be looked u])on as 

 distinct, and the name Ch. Dorice was given to it. In the 

 contrasted descriptions of the teeth of the two forms on p. 882 

 two important misprints have crejjt in, which, although they 

 might be detected on a careful reading of the whole paper, 

 yet, placed in so prominent a position, might easily deceive 

 any one working on the subject. The mistake consists of the 

 transposition of the dimensions of the posterior teeth of 

 Ch. Dorioe and Ch. villosum, so that each is made out to have 

 the dimensions of the other. The erroneous lines should 

 therefore read : — 



Ch. Dorice. Ch. villosum. 



Posterior upper premolar I Larger, combined Smaller, combined 

 and two molars ( length 7'4 mm. length 60 mm. 



Posterior lower premolar ( Combined length Combined length 

 and two molars ( 8' 2 mm. 6'3 mm. 



Thnnks to the kindness of Dr. H. Winge, t:ie National 

 Collection has now obtained from the Copenhagen Museum a 

 number of the specimens from Lagoa Santa described by him 

 in the valuable paper quoted above. Among these there is a 

 specimen called by him Cliiroderma villosum^ apparently in 

 ignorance of my paper, for on examination this proves, as 

 might be expected from its locality, to be an example of 

 Ch. Vorue^ agreeing in every respect with the type, except 

 that its outer incisors are rather shorter, perhaps owing to 

 greater wear. This very species, according to Dr. Winge, 

 was the one termed by Lund " Phyllostoma dorsale^'' but 

 without description ; so that my own much later name will still 

 have to stand for it. 



The full synonymy of the Minas Geraes species will 

 therefore be : — 



Chiroderma Dorice.
