described by Dr. Philippi, does not depart as widely from the 

 type as many of the Polynesian forms. 



None of the figures in Lister, referred to by Klein, represent 

 this species as supposed by Mr. Revee.

 Having received a number of specimens since my description 



was published, I add that the outer lip is finely denticulated 

 within and sinuated above. It is variable in color, being not 

 only marked by transverse opaque white spots, as described by 

 Mr. Reeve, but with few exceptions encircled by two or three 

 rows of brown spots, and occasionally its whole surface is closely 

 reticulated with fine brown lines. 



Sagitta, Gask., is a much thicker shell and may be distin- 

 guished from the above by its strong labial varix.

The name nana, originally attached to this species by Duclos, 

 and adopted by Kiener, was preoccupied by Dillwyn. Mr. Des- 

 hayes consequently changed it to pallida. The same year, how- 

 ever, it was described by Mr. Sowerby in his monograph as 

 poecila, which we adopt. The pale variety, well represented by 

 M. Kiener, is common at localities in Central Polynesia, and 

 does not vary from the type excepting in color. Poecila is 

 usually the largest in size and varies much in its color. It is 

 occasionally wholly black, with a narrow transverse white band 

 or whitish with transverse rows of black or brownish spots, and 

 sometimes variegated with white, brown and black.
