Melampus pallescens, Sowerby. 
SCARABUS, De Montford. 
Testa ovata, spira subobtusa, anfractibus depressis, varice obsoleto utrin- 
que notatis, ultimo interdum angulatim plicato ; apertura ovali, intro 
utrinque dentata, marginibus superné disjunctis, labro simplici, sub- 
expanso. 
Amongst the many new genera that were proposed by De Montford in 
his ‘Conchiliologie Systématique,’ there are, perhaps, few more entitled 
to notice than that which we have here ventured to adopt ; it was highly 
esteemed both by Lesson and De Férussac, and is for the most part ac- 
knowledged by modern authors. Without reference to the important cha- 
racters in the anatomy of the Scarabi recorded by the first of these authors, 
there is a peculiarity attached to the shell by which it can never fail to be 
recognised ; like the Ranelle, they form half a whorl between every period 
of rest, leaving an obsolete varix on each side ; and this is a character which 
we find in the shell of no other land mollusk. The typical species, which 
Linnzus included with the Helices, was amongst the number of those that 
were separated by Bruguiére for the formation of his genus Bulimus ; and 
it was subsequently removed by Lamarck to the genus Auricula. 
The shell of Scarabus may be described as being ovate, and obtuse at 
the spire, with the whorls peculiarly depressed, the last being sometimes 
turned very abruptly to the form of an angle; the aperture is oval, and
