1 6 Mathews and Iredale, " Perry's Arcana." [ V oi ct 'xxix 



Papilio phillis, Fabricius, from Mexico ; the lower, Plmlcena 

 corollaria, from North America. 



Plate XLVI. figures a Papilio of the division Arcuatus, which 

 Perry then called Arcuatus cceruleus. In the text Perry pro- 

 poses a new classification of the Papilionidae, naming the 

 divisions from the shape of the wings. His six divisions are 

 named — Arcuati, Orbati, Caudati, Excelsi, Cuspidati, and 

 Muscarii. Though noting these are divisional names only, 

 and using them as such, in a few cases, as the one under notice, 

 he omits the prefixation of the generic Papilio. 



Plate LI. is of a Phalcena of the division Arcuata, species 

 name vitrea, from South America. 



Plate LX. represents a Papilio which Perry called Arcuatus 

 catenarius, from the Brazils. 



Plate LXIX. is a beautiful figure of Sphynx castaneus, said 

 to have arrived from Port Jackson. 



Plate LXXIV. represents a Phalcena of the division Arcuatus, 

 but here called P. fenestra. 



Plate LXXXI. is of Papilio volcanica, from Rio de la Plata 

 and Peru. 



Paleontology. 



Plate XLII. illustrates a fossil Trilobite, which Perry called 

 Monoculithos gigantea, a generic introduction previously un- 

 noticed. 



Plate XLVIII. contains two more species of Perry's genus 

 Monoculithos, the specific names used being polymorphus and 

 hexamorphus. 



Botany. 



Plate III. in the first part is headed " Botany, PI. I.," and is 

 noteworthy as being the first and last to deal with a botanical 

 subject, the plate representing the Ceroxylon, or Palm-tree.
