ftfiangiiia magnoliana, n. sp., Plate 2, Fig. 11 



Shell large, slender, with the body -whorl more than one- 

 half the length of the shell; protoconch of about 3 whorls, the 

 1st smooth, soon followed by curved riblets and later with the 

 addition of 3-4 spirals; post-nuclear whorls 5; the spire-whorls 

 are strongly angulated a little above the middle; riblets 12-14 

 straight, on the whorls of the spire extending from the lower 

 suture upward and across the shoulder but soon disappearing, 

 the appressed suture being bordered by a broad band free from 

 transverse sculpturing; on the body-whorl, the spirals are fair- 

 ly regular and finely and closely frosted by transverse lines; a- 

 perture with a thin moderately expanded outer lip; canal some- 

 what bent. 



Length 7.5 y diameter 1.75 mm. 



The frosting of the spirals is fine and requires a lens to be 

 seen. They are easily destroyed by weathering and erosion, but 

 generally some portion of the shell surface will reveal them when 

 examined.

Mangilia emissaria, n. sp., Plate 2, Fig.6 



Shell large, with the body-whorl more than one-half the total 

 length of the shell ; whorl angulated ; nucleus — ; post-nuclear 

 whorls 5; suture distinct, not impressed; riblets about 8; on the 

 whorls of the spire, the riblets are strongest below the angulated 

 periphery, weaker above; spirals even, of narrow, flat bands, sim- 

 iliar over all and are not frosted; canal long and slender, slightly 

 bent ; anal sinus not evident ; aperture elongate with a thin out- 

 er lip. 



Length 10, breadth 3, aperture 4.5, body -whorl y mm. 



Characterized by its large size and few riblets. It appears 

 to be a rare species, the above description being based on a single 

 imperfect specimen.
