274 PARTULA, ROTUMA, FIJI. 



No. 4285 Carnegie Mus., four specimens labelled "Tu- 

 tuila. " Smaller than the preceding, the spiral striation not 

 so strong on the last whorl, lip flesh-tinted. Length 14 1 /^, 

 diam. 9, aperture 8y mm., whorls 4% 



P. gonochila Pfr. is no doubt closely related to subgono- 

 chila. In both the spiral striation of the embryonic whorls 

 is very fine and distinct, and the pitting is conspicuous. 

 P. gonochila is a more solid shell, darker colored, with the 

 lip more thickened within, and the upper part of the spire 

 more narrowly conic.

"Shell dextral, small, ovate, umbilicate, yellow-olivacous, 

 pale below the suture and towards the 'apex; spire moder- 

 ately produced, rounded at the apex. Whorls 5, a little con- 

 vex, closely sculptured with delicate growth lines and very 

 fine spiral striae, more or less obsolete on the last whorl; last

The single Fijian Partula, P. lirata, is very distinct by the 

 coarse spiral sculpture of the post-embryonic whorls and the 

 tubercular callus or tooth on the parietal wall near the 

 columella. 



P. lirata has no near relatives among known forms, and for
