Hoplophoms meyeri, Lund '. 



Syn. Glyptodon gracilis, Nodot -. 



Hoplophorus gracilis, H. Gerv^ais and Ameghino ^. 



This may be regarded as the type species ; and it will be 

 advisable to take as the type specimen the imperfect cranium 

 figured by Lund in the ' K. Danske Yid. Selsk. Skr. ' vol. xii. pi. li., 

 under the name of H. euiDhractus, which is different from that of 

 H. ornatus, although of the same generic type. The teeth figured 

 by the same writer in vol. ix. pi. xxxv. figs. 2, 4, are also referred 

 by Eeinhardt to this species, but the specimens figured in Lund's 

 earlier memoirs under the name of H. eiiphractus are referred by the 

 former writer to Glyptodon {Scliistopleurum). The characters of the 

 species are too imperfectly known to admit of diagnosis. 



Hah. South America (Brazil). 



M. 3617. A small fragment of the terminal tube of a caudal sheath 

 provisionally referred to this species ; from a cavern in 

 Minas Geraes, Brazil. The central disk in each scute is 

 smaller and more rugose than in the caudal sheath of 

 H. ornatus. Claussen Collection. Purchased, 1845. 



M. 3618. Two fragments from the anterior lateral portion of the 

 carapace, not improbably belonging to the present species ; 

 from Minas Geraes. The central disk of each scute is 

 relatively smaller than in the corresponding portion of the 

 carapace of H. ornatus. 



Claussen Collection. PurcTiased, 1845.

 phorus in the caves of Minas Geraes, and some of them may 

 prohahly he referred to the present form. All of them were 

 ohtained from Minas Geraes, and helong to the Claussen 

 Collection. 



18936 a. The nearly complete right humerus, showing the entepi- 

 condylar foramen. The proximal portion of this specimen 

 differs from the imperfect humerus from Brazil (No. 

 40675) provisionally referred to E. ornatus.
