2. A. horten'sis"^^ Ferussac. 



A. hortensis, Fer. Hist. Moll. p. 65, pi. ii. f. 4-6 ; F. & H. iv. p. 10, 

 pi. E.F.F. f. 1. 



Body longer than that of the last species in proportion to 

 its size, and of nearly an equal breadth throughout, brown, 

 red, yellow, grey, greenish, or black, usually more or less di- 

 stinctly marked on the back and sides with stripes or longitu- 

 dinal bands, and covered with coarse oblong tubercles : shield 

 having usually a dark stripe down the middle and another on 

 each side : tentacles not much swollen at their tips • foot nar- 

 I'owly bordered with grey, yellow, reddish, or orange : slkne 

 yellowish or whitish. L. 1-5. B. 0-35. 



Shell of an ii-regular shape, composed of grains like those 

 in the last species, but cemented together by a calcareous 

 matrix, so as to resemble tiny lumps of the conglomerate 

 which is called by geologists " breccia." 



Habitat : Under stones and dead leaves in gardens, 

 fields, and damp spots everywhere. Its foreign distri- 

 bution is also perhaps equally extensive with that of 

 A. ater. 



According to Bouchard-Chantereaux, the eggs of A. 

 hortensis are phosphorescent during the first fifteen days 

 after they have been laid. They take from twenty to 

 forty days to arrive at maturity, and the young become 

 adult towards the end of the first year. 



This species differs from A. ater in being much smaller 

 and more slender, as well as in usually having longitu- 

 dinal lines or stripes. The substitute for a shell is also 

 more compact, and making some approach to a definite 

 form, in the present species. Dr. Gray describes the 

 shell to be '^ distinct, oval, concave ;" but tliis description 

 does not agree with the generic character of this part of 

 the animal. 



It is the A. fasciatus of Nilsson. Miiller described
