sary alteration of the generally accepted nomenclature to pass without 

 protest. The common viviparous species of New South Wales is un- 

 doubtedly the typical Peripafus leuckarti ofSaenger. Saenger's 

 specific name must he preserved in the original sense, and the name 

 Orientalis must be allowed to drop altogether. The correct nomenclature 

 of the Australian species of Onychophoi^a is therefore as follows. 



1) Pcripatoides leuckarti Saenger (with 15 pairs of walking legs; vivi- 

 parous; characteristic of New South Wales, with a Yârieiy occidentalis 

 Fletcher, in Western Australia). 



2) Ooperipatus oviparus Dendy (with 15 pairs of walking legs-; ovi- 

 parous; characteristic of Victoria but extending northwards to Queens- 

 land). 



3) Ooperipatus insignis Dendy (with 14 pairs of walkings legs; 

 oviparous; characteristic of Tasmania and Victoria).

Since these notes were written I have learned for the first time of the 

 publication of the first instalments of M. Bouvier' s long expected 

 Monograph of the Onychophora^. In the introductory portions of this 

 magnificent work M. Bouvier refers in several places to the Austral- 

 asian species of the group, and does me the honour to accept my genus 

 Ooperipatus^ though, by a series of very unfortunate misprints, this name 

 is in many places confounded with the name Eoperipatus given by 

 Mr, Evans to a totally distinct genus. M. Bouvier appears, however, 

 to be still undecided as to the nomenclature of the Australian forms. 

 Ooperipatus insignis is in one place (description of plates) called Eoperi- 

 patus insignis, and in another place Eoperip. leuckarti, while Saenger's 

 original type (which is really, as shewn above, Peripatoides leuckarti) is, 

 on p. 17, designated Ooperipatus leuckarti. Judging from these inconsis- 

 tencies I venture to hope that the author has not yet irrevocably made 

 an his mind to adopt up erroneous nomenclature , and that he may still 

 he willing to reconsider the question in the systematic portion of his 

 monograph.
