Partula Tryoni, nol>i.<. 



Shell acuminately oblong, dextral, moderate!}' thick, rimate 

 perforate ; whorls 5, rounded, body-whorl equal to the 

 spire, oblique lines of growth coarse, spiral striae 

 almost obsolete; color pale fawn, with white oblong, 

 interrupted, lime-like dots, in oblique rows, in the sub- 

 stance of the shell; aperture perpendicular, ovate, with 

 a nacreous deposit connecting the margins of the peri- 

 treme, lip white, flat, and broadly expanded. 

 Length 21, width 12 mill.; aperture, length 9, width 4 mill. 

 Hub. — Solomon Islands. 



Obs. — For one example of this fine species I am indebted to 

 Mr. Garrett, who received it from our mutual friend, Dr. Cox, of 

 Sydney, Australia. Like P. actor Albers, = zebrina Gould, it 

 possesses the lime-like deposit in the substance of the shell. It 

 is a larger and more oblong shell than the latter, but like it, has 

 a broadly reflected flat lip. 



Partula flexuosa, n 



Shell acuminately oblong, flexuose, dextral, umbilicate, thin 

 and semi-transparent; whorls 5, slightly rounded, spiral 

 striae numerous and very fine ; body-whorl half the 

 length, slightly compressed at base ; color light brown 

 or ash ; aperture oval, slightl}" oblique, lip concave and 

 reflected, with a very thin deposit connecting the mar- 

 gins of the peritreme. 



Length 15 to 20, width 8 to 9 mill. ; aperture, length 

 7 to 8, width 4 mill. 



Hab. — St. George's and Kd<l\ stone Islands, Solomon Islands. 

 Obs. — Several examples of this shell, from Dr. Cox and Mr. 

 Garrett, have been in my possession for a long time, and I hesi- 

 tate to describe them, supposing they might be P. cinerea 

 Albers. Dr. Cox having kindly sent me all Ins collection of 

 Partula, for examination, I found the same shell amongst others 

 from Eddystone and St. George's Islands. Some examples are 

 thin and quite flexuose, while others are stouter and more 

 direct.
