The author describes a number of cases of variation in Agr. l<C7ns and many 

 other molluscs. 



Such observations as these only emphasise how important it is to establish 

 really sound anatomical features for purposes of classification, and the absurdity 

 of making new species upon slight variations. — W. E.G.

^"■Janella maculata, sp. nov. 



Animal much flatter thany^. hitentaailata. Dorso-median groove distinct and 

 continuous to the tip of the tail. Ground-colour dirty yellow, with numerous 

 irregular black spots and dashes ; a large, black, oval-shaped mark immediately 

 behind the pulmonary orifice. Head slightly lighter than the rest of the body. 

 Foot dirty yellow, marginal portions distinct from median plane. Pulmonary 

 orifice small and inconspicuous. Length in alcohol 33 millim. 



Habitat.— Forty Mile Bush, North Island, New Zealand (H. Suter)." 



This species differs from J. bitentaculata in the form and length of the free 

 oviduct and penis, the shortness of the common duct, the form and divisions of 

 the hermaphrodite gland, the distinct form of the albumen-gland, and the minor 

 differences in the liver, colour of the animal, and general flattened form of the 

 whole of the body.

 C. asteiiDi, Bgt., C. elegans. Mill!., and C. sulcatum, Drap. [C astcum appears
