18945. Several teeth, agreeing with those figured by Lund in the 

 ' K. Danske Vid. Selsk. Skr.' voL ix. pi. xxxiv. figs. 1-8. 

 Glaussen Collection. Purchased, 1845, 



The following specimens are also from Minas Oeraes, and 

 belong to the Claussen Collection. 



18937. The distal portion of the left humerus. In characters this 

 specimen agrees very closely with the corresponding bone 

 of Basypns sexcinctus ; the transverse diameter of the 

 distal articular surface is 0,057, against 0,016 in the 

 latter species. 



18943. An imperfect scapula. This specimen is apparently very 

 similar in structure to the corresponding bone of Dasypus. 



18643. Several phalangeals. 



18948. The nearly complete pelvis. In general structure this 

 specimen agrees very closely with the pelvis of Dasypus 

 sexcinctus ; but the sacral vacuity is less elongated, and the 

 ischial tuberosity produced laterally instead of vertically. 

 The diameter across the acetabula is 0,238 against 0,054 

 in the latter. 



18941. The centrum of the conjoint axis and third cervical vertebrae. 

 This specimen closely agrees with the corresponding bone 

 of D. sexcinctus ; the transverse diameter across the 

 anterior articular surface being 0,063 against 0,020. 



18941 a-42. Several imperfect vertebrae and ribs. 



Genus TOLYPEUTES, Illiger \ 



Teeth ^-^^ • Carapace with large scapular and pelvic bucklers, and 

 only three movable bands, the sculpture consisting of subconccntricall} 

 arranged granulations ; tail covered with large bony tubercles. Five 

 complete digits in the manus, the third being much the largest ; in 

 the pes there are also the same number of digits, the three middle 

 ones having broad flat nails. In the structure of the carapace this 

 genus makes the nearest approach of any of the living forms to the 

 Olyptodontidce.
