ANADENUS GIGANTEUS (type species). 
From original description, Length of spirit-specimen 80 to 100 mm. 
bes the mantle 30 to 40. ,, 
Colour isabelline, brownish. 
Internal shell 20 mill. long, 12 broad; flat, very thick. Jaw 
with fourteen ribs, distinct from each other; the last are grown 
together. 
Radula: 110 cross rows; the middle tooth slender, long-necked, 
with long point and signs of side points ; the side teeth not differing 
much, inclining inward, with still longer points, and likewise signs 
of side points, and in the less developed teeth towards the edge the 
points are still much longer with no side points. The upright position 
of the points (vide orig. fig. 1d, e, f), and which is most prominent 
in the side teeth, is also peculiar to Avion. From the size of the 
contracted median and from the circumference of the inner shell 
and the size of the teeth-plates we can conclude with some certainty 
that this species is of extraordinary length. Limax dorie of Bour- 
euignat, who says it is 360 to 450 mm. long (or 13 to 17 inches), 
has hardly from the plate (in Revue et Mag. pl. viii. June 1861) so 
large a shell. I do not maintain that this extraordinary length 
could be reached in giganteus. Equally interesting may it be in a 
living state from its bright colour, which certainly does not differ 
much in the spirit-specimen.

“This Zimax is rather variable in colour, and large specimens, 
when in motion and extended, exceed 9 inches in length, though 
their ordinary dimensions is about 6. It feeds on fungi.” 
This species is evidently the same as that described by F. D. 
Heynemann in 1863 under the title giganteus and the type of his 
genus Anadenus. The length of specimens contracted in spirit
