NELLA, AND OTHER REMARKS. 
By Dr. Newcoms. 
ACHATINELLA VIRIDANS, Mighels. Colour light grey, with two 
stripes of dark slate, extending back from the base of the superior 
tentacles. Tentacles strongly clubbed, rather short and robust ; 
mantle thick, of a yellowish-brown colour. When in motion longer 
than the shell. 
(Shell always dextral. Had. E. end of Oahu.) 
ACHATINELLA DECIPIENS, Nob. Animal slate colour; upper 
portion of tentacles intensely black ; mantle and bottom of foot light 
slate. 
(Shell often reversed. Hab. S.W. side of Oahu.) 
ACHATINELLA RUTILA, Nob. Animal small for the size of the 
shell, with long filiform tentacles, but slightly clubbed; colour light 
fresh. 
ACHATINELLA SUBVIRENS. Animal not observed. 
ACHATINELLA RADIATA, Gould. Resides more than 100 miles 
from A. grisea, and on a different island. The former is terrestrial, 
the latter arboreal in its habits. The first is usually dextral, the 
latter always sinistral. No comparison of the animals was made. 
ACHATINELLA RUBIGINOSA, Nob. Has the mantle uniformly of 
a light flesh colour, &c. A. teniolata, Pfeiffer, has the mantle 
always of a dark brown or black. 
ACHATINELLA GLABRA. No description, but is a very distinct 
species from A. elegans, never being found associated in the same 
localities ; the first is always dextral, the latter as often sinistral as 
dextral. 
ACHATINELLA RUBENS, Gould. Animal slate-coloured, traversed
