an anterior and a posterior buckler with several movable

 Although referred to the Dasypoda, the genus is recognized 

 as in many ways intermediate between the armadillos and 

 the glyptodonts. 



The presence of the genus Ghlamytherium in the late 

 Cenozoic deposits of Florida was first made known by Joseph

The canal, the location of which is seen below the specimen number, is apparently a 

 character of generic, or more than generic value, as it is observed not only on this species 

 but also on C. humboldtii and C. paranense.

 collected on Peace Creek by Mr. Joseph Willcox in 1888. 

 These plates were at first described b} r Leidy as Glyptodon 

 septentrionalis sp. n. Afterwards, however, all of the plates, 

 including the types of Glyptodon septentrionalis, were referred 

 to Ghlamytherium {Ghlamydotherium) humboldtii Lund. 

 Subsequently additional scutes were obtained from other 

 localities in Florida, all which were referred to G. humboldtii. 

 By the fortunate discovery of additional material of the genus,
