arated by the costate surface of Mr. Anthony's species and 

 the uniformly smooth surface of trilineatus. Mr. Reeve's fig- 

 ure of trilineatus is very poor ; the bands are so represented 

 as to appear like ribs. It is by no means certain that trilin- 

 eata is an Anculosa. Its small size and smooth surface and 

 general outline suggest its pertinence to the Amiiicolidce, to 

 which family several small species, hitherto considered to be 

 Anculosce have been recently removed. It differs from all 

 the Avmicolidce, however, in possessing colored bands. The 

 figure of trilineata is from Mr. Say's type in possession of Mr. 

 Anthony. Viridis is a copy of Mr. Lea's excellent figure.
