and three other species was one of the precursors 
ISTORY.—A rion ater (ater, black), is the 
largest of our native species, and was first 
made known by Dr. Martin Lister, in 
1674, under the’ descriptive epithet of 
Limax ater, and he afterwards, in 1678, 
gave a good figure in Hist. Anim. Angl. ; 
considerable confusion and uncertainty 
has, however, arisen owing to the wide 
range of colour mutations to which it 1s 
subject, and many species have been 
created to receive them. 
The name empiricorum (in allusion to 
its former use in medicine), bestowed 
on this species by Baron Férussac, was 
intended not to separate any particular 
form, but to unite under one denomina- 
tion all the different varieties and so- 
called species into which this protean 
slug had been divided. It has in other 
parts of its range also received many 
distinct names, based upon the shght 
external modifications it has undergone. 
With this species is associated the late 
Mr. Thomas Nunneley, F'.R.C.S., of Leeds, 
whose careful and conscientious memoir 
of 1837 upon the anatomy of the present 
of the modern scientific 
study of slugs, and it is to be regretted that his professional career as a 
distinguished and skilful surgeon did not leave him leisure to follow up his 
anatomical studies of the mollusca.
