is allied to Vinata and Devadanda, and by the structure of 

 the antennae more to Vinatn ; the position of their insertion, 

 the structure ot" the face, and the single series of transverse 

 veins to the apical areas of the te«!;niina will, however, prevent 

 any confusion. It is more nearly allied to the Australian 

 genus Kuranda, Dist.

[Plate IX.] 



In 1892, when studying Devonian fishes in the University 

 Museum of Dorpat, I observed a large, ovoid, convex dermal 

 plate exhibiting the characteristic texture and ornament of 

 Fsammosleus paradoxus *. On returning to London I 

 identified a rough papier-machd copy of this plate which 

 had been presented to the British Museum by Sir Iloderick 

 Murchison in 1842, but had not previously been determined f- 

 Some time afterwards Mr. William Taylor discovered in the 

 Upper Old Eed Sandstone of Newton Quarry, Elgin, a nearly 

 similar plate, which he presented to the Royal Scottish 

 Museum ; and the close resemblance of this plate to the 

 Russian specimen was soon recognized by Dr. Traquair when 

 he examined the British Museum cast for comparison.
