THE MEDITERRANEAN NATURALIST 
close examination, yet the L. melitensis is not 
only a species well distinct from others, but that 
a particular section ought to be made for it in the 
Genus Malacolimax where it should find its place. 
“ I establish then, he says, for this species the 
subgenus Melitolimax, which preserving the radula 
of the other Malacolimaces — central tooth triacu- 
leate, median teeth biaculeate — has a generative 
system similar to that of the Lekmannia , viz the 
very short, with a Jatero-terminal flagellum. 
The digestive tube has six circumvolutions the 
last of which is provided with a caecum of smaller 
dimensions than that observed by me in M. Va- 
lentinus Ferf 
The subgenus Melitolimax is according to his 
opinion a connective link between the Lehmannia 
and the true Malacolimax. 
Prof. Simroth on his part regards this species 
I have met with this slug under moist stones in 
many other places in Malta, besides the locality 
mentioned by Issel e. g. Makluba, Uied Encita, 
Fort Manoel, Imtahleb; but it is never abundant. 
I have never found it in Gozo. 
I must also note a forma pallidissima of it, of 
a very pale colour, which I found with the type 
at Makluba.

has the penis

does not ap- 
pear to be at 
all common. 
There is a 
forma con- 
color of this 
slug, which 
has nopoints 
whatever, 
and is shield 
and all of an 
that the L. melitensis might as well be considered 
as another marked variety of the L. arborum. 
He therefore does not acknowledge the necessity 
of creating a new subgenus for it. 
Whether it be considered as a distinct species 
by itself or a variety of L. arborum , its affinities 
with L. vcdentianus are certainly very marked, 
and the question as to under what section it must 
fall depends from the greater or less extension 
which is given to these, what is important for us 
to state is thad specifically regarded, I. melitensis 
is a well defined local form, 
uniform tint, I collected it at Migiarro, Gozo. 
In alcohol this species looks like a small A. 
agrestis from which it differs principally in the 
blackish carina which shows itself in dark relief 
on the back. The living animal differs from the 
A agrestis much more, because besides the above 
mentioned character it differs in its general gela- 
tinous appearance, in having a 'transparent and 
watery mucus instead of a milky and opaque one; 
in the length of the shield and in its rugosities 
which are rougher and less numerous than those 
of A. agrestis approaching it to A. brunneus .
