Wagler (1830), is considered available. Perry's Guanaco seems 

 to claim usage, being nineteen years earlier than Wagler' s 

 name. 



Plate LXXII. is a skull of the fossil Elk, Cervus fossilis. 



Plate LXXIII is of Dipus tridactylus, or Kangaroo. 



Plate LXXVI. figures Equus zebra. 



Plate LXXVI I. illustrates Ovis aries. 



Plate LXXXIII. is of the Hyaena. 



Reptilia. 



Plate V. is a picture of the Rattlesnake, Crotalus horridus, 

 Linne. 



Plate XXV. is a new Chameleon, called Chamceleo pallida, 

 from Egypt. 



Plate XXXIII. figures a tortoise from Panama, which Perry 

 calls Testudo panama. 



Pisces. 



Plate VIII. is of Spams bandatus. 



Plate XVIII. is of the Sea Horse, genus Syngnathus, or 

 Hippocampus, species foliatus, a native of Botany Bay. In the 

 text is written : — " The Hippocampus, or Sea Horse, has been 

 always placed by the most eminent naturalists with Syngnathus 

 and .... The fish called Syngnathus, or 

 Pipe Fish, we cannot help considering as decidedly distinct 

 from the proper Hippocampus, to be divided into a separate 

 form, and we regard the different form of the tail already 

 described as quite sufficient reason." This is the first use of 

 Hippocampus generically, and as type must be quoted H. 

 foliatus. 



Plate XXVI. purports to figure a new species of Stromateus 

 — viz., depressus. 



Plate XLV. represents Hippocampus erectus, and in the text 

 we again note : — "In a former number of the ' Arcana ' (for 

 May) we imparted to our readers a new species of this curious 

 genus. . . '. The Hippocampus erectus is a native of the 

 American Seas." Plate XVIII. is here referred to, confirming 

 the conclusion that four plates were regularly issued monthly. 



Plate LV., figuring Congiopodus percatv.s, appears to intro- 

 duce a new generic name which has not hitherto been noticed. 



Plate LXIV. is of Esox niloticus, from the Nile. 



Plate LXXIX. figures Zeus faber, or John Dory. 



Insecta. 

 Plate IV. gives figures of two species of Fulgora — F. pyro- 

 rhynchus, from " Bengal," and F. candelaria, a native of China. 

 Plate XXIV. figures Mantis foliaceus. 

 Plate XXXI. is of Papilio demosthencs, from the Brazils. 

 Plate XXXVII. contains two figures — the upper one of
