Aldrich {loc. cit.) saj-s of this ''suba7tgulatus'' var.: "Shell 

 small, depressed, whorls five, rapidly increasing in size; surface 

 covered with fine revolving lines, umbilicus deep; aperture ap- 

 proaching quadrate, suture distindl. 



"This agrees with Meyer's description and figure. If new, 

 however, it may be called S. liniferus. Type [of subangtilatus\ 

 was obtained at Jackson, Miss."

Adeorbis sylvaerupis n. sp. PI. 12, fig's. 3, 4. 



Specific characterization. — Size and general features as indicated 

 by the figures; whorls about five; surface depressed just exterior 

 to the suture; spiral lines, raised, sharp, increasing in strength 

 from suture to the peripheral, the eighth line, which carinates the 

 whorl; below a sub-carina and between it and the umbilicus 

 three more small spirals; umbilicus large, 'smooth. Between the 

 carinal and sub-carinal lines there is generally a more or less con- 

 spicuous revolving line, though no trace of it is to be seen on 

 the type specimen. 



Differs from A. exacuus Con. by (i) the presence of two raised 

 spirals in the subsutural depression in place of a large number of 

 fine hair lines, (2) the entire absence of hair line spirals between 

 the high raised lines, by (3) the lack of the broad, flattened base 

 of the body whorl of exacuus, (4) the presence of three well-de- 

 veloped spirals and a sub-carina beneath.
