" As an addition to Mr Kirby'.s note specifying didactylus as the 

 type of PteropJwrus, I would add — but as * didactylus, Geofifr. 

 (nee L.) = JHOJiodactyla, L., the type of PtcropJioriis, Geoffr. is of 

 course Alucita vionodactyla, L. {=* didactylus, Geoffr.)."] 



132. Fern ALL) (C. H.). 



" I have heretofore regarded mofiodactyla as the type of A lucita, 

 as it is the first species given under it by Linnaeus, but if Poda in 

 his work, which I have never seen, constituted pentadactyla the type 

 oi Alucita, as stated by Lord Walsingham*, I see no reason for not 

 adopting it, unless there be good reasons for rejecting Poda, as inti- 

 mated by Mr Meyrick**. I wish Mr Me}'rick had given his reasons."

Professor Fernald, in T/ie Pteroplioridae of North America 

 (January 1898), has d.do^t&d pcjitadactyla as the type.]

" I am quite agreed with Lord Walsingham on this point."

"Alucita, L. type hexadactylus (vide above)" i.e. 



[If the characters of a genus are better or in a higher degree 

 developed in one species or in one group of species than in others, 

 I think that species or that group must be held as typical. Linne 

 gives Syst. Nat. X. p. 496 as characters of Alucita 'alis digitatis, 

 fissis ad basin.' The first species vwnodactyla cannot be taken as 

 type as not wholly agreeing with the description, but in the last 

 s^&ci&s,hexadactyla, the characters given by Linne are best developed, 

 and I therefore agree with Zeller, Herrich-Schaefifer, Wallengren 

 and others in taking that species as the type o^ Alucita, L.' [Auri- 

 villius 81 § rt'.]. 



Pteropkorus, which name was first introduced in the binomial 

 nomenclature by Fabricius (1773), is nothing more than a synonym of 

 Alucita, L. Geoffroy never used the binomial system before 1783.'" 



[Aurivillius subsequently adopted pentadactyla as the type; vide

"I believe pentadactyla to be the type, as shown b>' Lord 

 Walsingham*."
