Animal as long as the shell, anterior superior portion a dark 

 brown, with tentacles of same color, posteriorly cut up into 

 squares and other geometrical figures by light-colored lines. 

 Mantle light flesh color, bottom of foot light green. 



The type of Dr. Pfeiffer's species is a large sized A. sangui- 

 nea, with the black markings carefully removed by design or 

 accident. This specimen is in the magnificent museum of Mr. 

 Cuming.

 " macrostoma Pfr. Zool. Proc. 1855, pi. 30, fig. 6. 



Animal small in proportion to the shell, of a uniform yel- 

 lowish white, retractile part of upper tentacles of a light 

 brown ; — tentacles filiform and slightly clubbed ; foot very 

 broad, long as the shell ; mantle same color as the animal. 



It will be seen by comparing the animal of this species with 

 that of A. viridans, that they are clearly distinct ; and Dr. 

 Pfeiffer, by taking an extreme variety of this species for his 

 A. macrostoma, thus gives evidence in its favor. This last- 

 named is in the collection of Mr. Cuming.
