PARTULA, NEW HEBRIDES. 283 



engraved with distinct spiral lines which are somewhat separ- 

 ated on the penultimate whorl and front of the last one, but 

 on the latter half of the last whorl the spiral striae are close, 

 with deeper lines at short intervals. The later whorls are 

 strongly convex, but the last becomes compressed laterally, 

 towards the aperture, and is sack-like below. The umbilical 

 chink is deep and wide. The color is a slightly bluish milky 

 white, without markings. Length 21.8, diam. 12.2, length of 

 aperture 11.2 mm.; whorls 5%. 



While it is closely related to P. caledonica, macgillivrayi, 

 eximia etc., this species is distinct by the absence of color 

 streaks and the persistence of spiral striae over the whole 

 last whorl. 



I have been unable to find an Aura Island in the New 

 Hebrides. Probably Arag is intended. Sitova is also un- 

 known to me. 



72. P. TURRICULA Pease. 



Shell elongate, 'turriculate, solid, sinistral, rimate-p erf orate, 

 glossy, smooth, delicately marked with growth-lines; buff, 

 indistinctly rayed with darker streaks. Spire turriculate, 

 rather acute. Whorls 5%, plano-convex, the last shorter than 

 the spire, obliquely produced. Columella vertical, heavily 

 calloused, broadly dilated above, especially over the umbilicus, 

 transversely subsuloate. Aperture oblique, oblong, obliquely 

 truncate behind. Peristome white, calloused, expanded and 

 reflexed, slightly sinuated posteriorly. Length 20, diam. 10 

 mm. (Pease).

"The habitat of -the above species is doubtful. From its 

 approaching P. macgillivrayi, Pfr., and caledonica, Pfr., in- 

 habiting the New Hebrides, and having lately received speci- 

 mens from Dr. Jas. C. Cox, with other species from that group 

 of islands, there is little doubt but that locality is -the correct 

 one. It differs from the species mentioned above in being
