Arr. XX.—Notes on the Anatomy of the Bitentaculate Slugs of New 
Zealand. By Professor F. W. Hutton, of Canterbury College. 
[Read before the Philosophical Institute of Canterbury, 3rd March, 1881.] 
Plate V. 
In the ‘ Transactions of the New Zealand Institute,” vol. xi., p. 332, I 
described a new genus of bitentaculate slugs under the name of Konophora. 
This year, through the kindness of Professor Parker, I have been enabled 
to examine another specimen, and find that after having been in spirit 
for some time a lateral groove appears dividing the body from the foot, 
as in Janella, and that the anatomy is so like that of J. bitentaculata that 4 
new genus seems hardly necessary for its reception. I therefore propos? 
_ to regard Konophora marmorea as a species of Janella, distinguished from 
the other two species by not tapering rapidly to the tail, by its conical bodes 
peduncles, and by the form of the central row of teeth, as 
further on,
