SiMROTH (336) has made a detailed anatomical and biological investi¬ 
gation of the slugs of Germany. They may be arranged thus :— 
I.— Limax. Slugs with 6 intestinal loops. 
1. With 6 intestimal loops, but no csecum ( Limax proper). 
L. maximus ( cinereo-niger , L tenellus. 
cinereus, unicolor , trans- L. nyctelius. 
sylvanicus,corsicus,subg. L. cosrulans. 
Dorice, var. simplex, var. 
rubronotatus , montanus ). 
2. With 6 intestinal loops and a caecum ( Lehmannia or Simrothia ?). 
L. variegatus (ecarinatus). L. arborum (var. tigrina, 
var. diance). 
II.— Agriolimax. 
A. agrestis (var. florentinus, 
var. panormitamus). 
A. Icevis. 
A. melanocephalus . 
III.— Amalia. 
A. dymczeiuiczi. 
A. berytensis. 
A. maltzani , sp. n. 
J.. marginata. 
A. carinata var. sowerbyi. 
A. carinata . 
J.. gracilis (buclapestensis ). 
IV.— Paralimax. 
P. intermittens. 
A. gagates (raymondiana). 
A. robici, sp. n. 
-4. cretica , sp. n. 
V.—^4 now. 
4. empiricorum. A. minimus , sp. n. 
4. brunneus (subfuscus ). 4. hortensis. 
A. bourguignati. 
Definitions of the genera based on the anatomy are drawn up in a tabular 
form (pp. 252 & 253). In Agriolimax, a phylogenetic arrangement based 
on the extent of variation and geographical distribution would indicate 
4. agrestis and 4. Icevis as the most primitive forms, while anatomical 
considerations would point out 4. melanocephalus and 4. dymczewiczi. 
Agriolimax and Amalia originated in countries surrounding the Medi¬ 
terranean ; if they came thither from Asia it was probably by the south, 
from one peninsula to another. The best marked species of the latter 
appear to be A. gagates, A. marginata , 4. robici, and 4. cretica', the 
others may be regarded as merely local forms. The two last belong 
to the section Malinastrum , adopted for those forms which have no keel. 
Limax yields different classificatory results, according as these are based
