PARTULA, SOLOMON ISLANDS. 295 



This species has not been figured. Hartman's statement 

 that it occurs on the Fiji Islands was 'based upon an erroneous 

 identification. 



Group of P. micans. 



Small, ovate, thin forms, with corneous, pellucid cuticle 

 and usually very distinct spiral stria? ; whorls 5 or less. 



88. P. MICANS Pfeiffer. PI. 36, figs. 10, 11, 13, 14. 



Shell deeply rimate, subperforate, ovate-conic, thin, dis- 

 tinctly decussated with close growth-stria? and spiral lines, 

 diaphanous, slightly glossy, pale corneous ; spire conic, rather 

 acute, the suture deep. Whorls nearly 5, convex, the last as 

 long as the spire, rounded at base. Columella lightly arcuate. 

 Aperture slightly oblique, oblong-oval; peristome whitish, ex- 

 panded, acute, the margins converging, columellar margin di- 

 lated, spreading. Length 15, diam. 8, aperture with peris- 

 tome 8 1/2 x 6 mm. (P/V.).

Partula micaits PFR., P. Z. S. 1852, p. 138; Monographia 

 iii, 451 ; Conchyl. Cab., p. 276, pi. 66, f . 12, 13. 



The shell is larger than P. pellucida, with a half whorl more. 



Pfeiffer's figures of the type are copied, pi. 36, figs. 10, 11. 



Specimens from Shortland I. are figured, pi. 36, figs. 13, 

 14, for comparison with P. similaris and other related forms. 

 The spire is shorter than that of P. similaris, with not quite 

 5 whorls, the last one convex, shaped about as in similaris, 

 being much less compressed laterally than P. coxi. The lip 

 is only very slightly thickened within, much less than in 

 coxi, similaris etc. The spiral striation is weaker on the 

 last whorl than in the allied species. Color very pale honey 

 yellow, slightly transparent. The suture is marked with a 

 whitish line. Sometimes a margining thread may be seen 

 above it on the last whorl, but in other shells this is con- 

 cealed. The last half whorl is impressed just below the 

 suture, forming a sort of margination there. 



Length 15^, diam. 8%, aperture 8 x 5% mm.
