PARTULA, LOUISIADE ISLANDS. 



"P. elongata Pease, and P. gracilis of the same author, from 

 the Tahiti group, closely resemble this species. The former 

 is rather larger and broader, not so strongly spirally striated, 

 and more or less striped with pale brown. The latter has a 

 longer aperture, rather more convex apical whorls, and a pecu- 

 liar bulging at the lower part of the body-whorl. P. minuta, 

 Pfr., also from the Admiralty Islands, is similarly sculptured, 

 but of a totally distinct form." (E. A. Smith}. 



Mr. Smith's description and figure (fig. 7) are copied. 

 One of the specimens from Wild Island before me is smaller, 

 length 141/2, diam. 7, aperture 7.2 mm., with 5 whorls. The 

 aperture of this example is quite oblique (pi. 37, fig. 6). In 

 a larger specimen the aperture is almost vertical. The peri- 

 pheral cord common to other species of the group is visible 

 above the suture, which is also very distinctly marginate be- 

 low, on the last half whorl. Spiral striation is very dis- 

 tinctly developed throughout.

"Shell dextral, oblong-ovate, thin and translucent; whorls 

 5, convex, spire half the length, oblique lines fine and de- 

 cussated by coarse spiral stria?, umbilicus compressed; aper- 

 ture rounded ovate ; lip white. Color yellowish white, with the 

 apex very pale rose. Length 17 mm., diameter 9 mm. ; length 

 of aperture 6 mm., diameter 4 mm." (Hartman).

'For size and contour this shell is near P. carteriensis, 

 Pfr. ; it is thinner and less solid, with a more rounded aper- 

 ture, and concave lip." (Hartm.)
