rest of the skeleton is nearly entire. The slab with de- 

 tached bones from the Muschelkalk of Silesia figured by 

 Meyer in the 'Saurier des Muschelkalk,' pi. lxvi. fig. 1,

Purchased, 1881. 



R. 54. Slab exhibiting the ventral aspect of a skeleton wanting the 

 (Fig.) skull and anterior cervical region, the left pelvic limb, the 

 termination of the caudal region, and the distal portions 

 of the other limbs. The second type ; portions figured by 

 Fraas, op. cit. figs. 2-4, and the entire specimen by Seeley, 

 op. cit. pi. xiii. fig. 2. Same history. 



Note on Macromerosatjrtjs plush, Gurioni \ 



This reptile from the Italian Trias is referred by Baur, in the 

 * Zool. Anzeiger,' vol. ix. p. 247 2 (1886), to the present family ; but 

 Deecke, ' Zeitschr. deutsch. geol. Ges. vol. xxxviii. pp. 190, 191, con- 

 siders it to be more nearly allied to the Rhynchocephalia or Protero- 

 sauria. The pectoral girdle appears to be of a Sauropterygian type.
