310 Synojysis of the Genus Achatinella. 



I am sorry to be obliged to place so many synonyms nnder 

 this species. The very short description and unsatisfactory 

 figure given by Swainson, have doubtless contributed to this 

 result. A complete series to connect the extremes of these 

 varieties will demonstrate the necessity of making at least a 

 dozen more species, or to include them all under one. Mr. 

 Griiliek is mistaken in supposing that the variety figured by 

 Mr. Reeve is not found on the Island of Oahu. 



This and all the other varieties are met with in the District 

 of Waialua, and it is an interesting fact, that all the species 

 described by Mr. Swainson are from the same district.

The type of A. oomorpha Gul. is this species; but specimens 

 furnished to Mr. Cuming of London under that name are the 

 true glabra Kewc. The beautiful reversed variety called by 

 Mr. Gulick A. obliqua is widely known, and almost uniformly 

 admitted by Conchologists as A. bulimoides.

Animal light flesh colored, tentacles, tentacular sheath and 

 front above, dark brown ; outer margin of mantle grey ; tenta- 

 cles wide apart, short, moderately clubbed ; foot rather broad 

 and thin, when extended as long as the shell. 



A. ventrosa of Pfeiffer forms a very striking variety, with 

 the whorls rounded, aperture contracted, and the whole shell 

 pressed together. 



The figure referring to A. lorata in Reeve's Monograph is a
