Plate LVIII. is lettered Buccinum dilatum, but the text is 

 headed Buccinum orbiculare. It is a good figure of the shell 

 later named Dolium maculatum by Lamarck (An. s. Vert., 

 vol. x., p. 140, 1844), and, as both Perry's names have priority, 

 we prefer the text name, and therefore Tonna orbicularis, Perry, 

 must be used for the shell now called Tonna maculata, Lamarck. 



Plate LXIL, named Trochus zebra, is a fair figure of Trochus 

 niloticus, Linne. 



Plate LXVI. is called Buccinum distentum, and of which Perry 

 writes : — " It differs from others chiefly in the shortness of the 

 rostrum or beak, and more especially from that which we have 

 described formerly in No. XV. of the ' Arcana.' " The figure 

 is indeterminable, but seems to have been drawn from a specimen 

 of Turbo petholatus, Linne, and, the mouth having been 

 damaged, the artist has imagined a canal. No. XV. of the 

 " Arcana," above referred to, would contain Plate LVIII. , 

 where the other dissimilar Buccinum is figured, and it would 

 follow that four plates to each number had been adhered to. 



Plate LXXL, of Pecten sanguineum, from the Red Sea, is 

 another indeterminable figure. 



Plate LXXV. is a figure of Strombus chiragra, Linne, which 

 Perry named on the plate Strombus diver gens and in the text 

 Strombus nigricans. 



Plate LXXX., giving a splendid figure of a Cone which Perry 

 called Conus bandatus, is another of his puzzles. It is quite 

 indeterminable, but may have been drawn from a specimen 

 of Conns miles, Linne, to which has been added a little imagina- 

 tion by the artist. 



Plate LXXXIV. is entitled Pinus. The text is headed 

 " Class Fossilia, Order Univalvia, Species Rostellaria." This 

 last would seem to have meant genus, and the text bears this 

 out, but " appears to belong to the genus Rostellaria." 



ECHINODERMA. 



Plate XXXIV. is of Echinus castaneus, a native of the South 

 Seas and of the coasts of New Holland. 



Plate XXXVIII. represents Echinus stellar is, from the 

 South Seas, and in the text another species is mentioned as 

 Echinus sceptriferus. None of these names appear to have been 

 noticed before in literature. 



Mammalia. 



Plate I. figures the Tiger, Felis tigris, Linn. 



Plate X. is of the Platypus, or Ornithorinxus paradoxus, from 

 New Holland. The text contains the following : — " A second 

 animal of the same genus, and which may be called the Platypus 

 longirostra, has lately been shot in Adventure Bay, at Van 

 Dieman's Land." Then follows the description, which seems
