' * The two Partulae described 'by Lesson have, -as Tapparone 

 remarks, a doubtful claim to Papuan soil, and, omitting these, 

 the above species is the first described from New Guinea 

 proper. ' ' ( Hedley. ) 



S'amarai is a small island lying off the eastern extremity

This species is more lengthened and thinner than any other 

 known to me. The penultimate whorl is longer than in the 

 species already mentioned [P. otaheitana, rufa, lineata, luted] . 

 The last whorl, finally, is but little dilated, little swollen. 

 The aperture is directed to the right. It is higher than wide, 

 with the peristome thick, a little dilated in front of the um- 

 bilical chink. The surface of the shell is very finely striate 

 longitudinally and transversely, hence covered with a fine 

 and granulose network. The 'aperture is white. All the 

 rest is uniform light gray. Length 8, diam. 3% lines
