 gdgates." Ann. Sci. Nat., Porto, vol. ii., 1895, PP- 89-96. 



The author points out that the colouration of young slugs represents an 

 ancestral condition such as is seen in the lion-cub which is spotted. In 

 Limax maximus the young ones of all the colour-forms— c/HiTfOH/^^r, unkolor, 

 etc., etc. — are alike ; very young individuals of the genus Avion belonging to 

 the same species are of a colour peculiar to that species, but later on variations 

 come in ; in Amalia the young are usually like the parents, which vary 

 geographically. 



All the young of a black specimen of Amalia gagates were in the first place 

 white with a semi-circular band of black on thn mantle, one turned a reddish 

 colour with a greenish tint on the sides, and of three others reared together, 

 two became black, while the remaining one took upon itself a grayish tint 

 with a suspicion of ochre.

 This continuation of the bivalves contains figures and descriptions of a 



number of new varieties. The exhaustive synonymy is strongly to be 



commended.
