number of teeth, but has two of them on the transverse lip, in- 

 stead of on the columella. 



Pupa peponubi. Testa minuta, variabilis, ovata, plus minusve 

 elongata, tenuis, lucida, nitida, fulvo-cornea, perforata : spira 

 anfr. 6 convexis leviter striatis : apertura ovato-rotundata, pos- 

 tice lamellam volventem gerens ; labro simplici, ad columellam 

 plerumque late revoluto ; columella vel nuda vel lamellis trans- 

 versis 1-3 instructa. Long. / a , lat. ^ poll. Hab. Sandwich 

 Islands ; very abundant on pumpkin vines. 



This interesting little shell is of somewhat doubtful genus. It 

 may prove to be of the genus Tornatellina or Elasmatina. Its 

 very variable characters render a decision difficult. But it be- 

 longs to the old genus Pupa, where I at present place it. 



Pupa (Megaspira) elata. Testa sub-cylindrica, elevata, tenuis, 

 nitida, striis conspicuis lirata, cornea, lituris parvis sparsis prope 

 suturam notata, vix perforata: spira obtusa, anfr. 19 angustis 

 sub-planulatis : apertura parva, obliqua, lunata, antice sub-effusa 

 postice lamellam volventem gerens ; plica columellari modica, 

 bilamellata. Long. 1^, lat. ^ poll. Hab. Brazil. 



Compared with P. elalior it is smaller, more cylindrical, more 

 delicately striated, more shining, the whorls more crowded, be- 

 incr as 19 to 16 in the same space, the columella smaller and 

 with one fold less, the lip effuse and the umbilicus much smaller. 



Balea peregrina. Testa parva, sinistrorsa, elongata, sub-fu- 

 siformis, solida, opaca, rufo-cinerea, vix striata, perforata : spira 

 ad apicem mamillata ; anfr. 8, planulatis, sub-tabulatis ; sutura 

 lineari, profunda : apertura sub-quadrata ; peristomate continuo, 

 sequato, leviter refkxo. Long, §, lat. T \y poll. Hab. New 

 Zealand. 



I have referred this shell to the genus Balea with much hesi- 

 tation, on account of its locality. It is remarkable for its fusi- 

 form, turreted shape, and for the high walls of its aperture, 

 which rise to a level with the surface of the shell. 



Achatinella marmorata. Testa oblongo-ovata, coloribus 

 castaneis, cinereis, et albidis marmorata, leviter striata, imperfo- 

 rata : spira acuta, anfr. 6 convexis, superne sub-tabulatis, ultimo 

 ma°-no, ventricoso: apertura ovata; peristomate simplici, mo-
