MOLLUSCA 307 
The variation is, as usual in the group, very great. A long series collected by 
Mr Hutchison, added to those of Mr Perkins, has led me to be unable to form any 
definite break between the various described species which are here placed as varieties. 
A, pulcherrima appears to be a large race in which the colouring has been broken into 
bands. A. multicolor and A. recta are, | think, only dwarf varieties. The sinistral 
shell figured by Pfeiffer (oc. cz¢. pl. xxx. fig. 11a) as a variety of A. multicolor 
belongs really to A. ovtformis. A. nympha seems a small, elongate, almost colourless 
variety, with a white lip.

I cannot trace this species in the Brit. Mus. ; it seems not to have been recognized 
by any recent author.

Only two dead specimens. I think A. frick?, which Newcomb placed with 
Al. ovata, really belongs here ; fig. 7 a, however, belongs to A. ovata. The determina- 
tion of A. wheatleyi is from specimens so named in the Brit. Mus.
