APPENDIX 1. 



ADDITIONAL NOTES, AND NEW SPECIES OF ACHATINELLID^E. 

 Genus NEWCOMBIA Pfr. 



This volume, page 1. The word sinistral should be added to 

 the generic diagnosis. 



N. pfeifferi and cinnamomea live chiefly on the bark of 

 small trees where they stick twig-like, often in a fork, and are 

 hard to see. N. plicata has the same habit. 



N. sulcata and gemma live on leaves, according to Mr. Thaa- 

 num. N. canaliculata lives on lehue and lantana. 



NEWCOMBIA PLICATA (Migh). Page 3. Add the localities: 

 Waialue (Thaanum) ; small trees overhanging the pali at top 

 of Leper Settlement trail (Cooke & Pilsbry). 



NEWCOMBIA PFEIFFERI (Newcomb). Page 13. This form 

 does not occur at or near Puu Kolekole (a locality for cinna- 

 momea), and that locality should therefore be deleted. Dr. 

 Cooke and Mr. Thaanum hold that pfeifferi and cinnamomea 

 are extremes of one species ; a view which their collections sup- 

 port. The subspecies called ualapuensis Pils. belongs to 

 pfeifferi rather than to cinnamomea. The distribution of the 

 forms is rather peculiar. Beginning at the eastern valleys 

 and going westward, the forms are encountered thus: 



Honomuni honomuniensis. 



Ahaino decorata. 



Kupeke decorata. 



Pukoo fossil cinnamomea (Thaanum) . 



Mapulehu cinnamomea. 



Kaluaaha pfeifferi. 



Ualapue ualapuensis. 



Kahaanui ualapuensis. 



(Several valleys wanting.) 



Makolelau cinnamomea. 



Makakupaia cinnamomea.
