t P. mucida Pfr., P. Z. S., p. 98, 1855. The type of this shell in the Britisb 

 Museum = a large dark specimen of P. varia. 



P. MINUTA Pfr., P. Z. S., p. 384, 1856. Admiralty Island. This species is 

 more globose than any other described Partula.

t P. nitens Pfr., P. Z. S., p. 293, 1854. New Hebrides, Taylor coll. This 

 shell only differs from specimens of P. affinis in possessing a broad, light band, 

 beginning at the base, and becoming narrower towards the apex ; it has the form, 

 button-like pillar tooth, and polished surface of P. affinis. A similar specimen 

 occurred amongst the Pease duplicates of P. affinis from Tahiti. 



t P. NODOSA Pfr., P. Z. S., p. 262, 1851. Tahiti, Samoa, Garr. Specimens of 

 this shell in A. N. S. Phila. ex auctore from Tahiti^ dark specimens of P. tri- 

 lineata Pse. Some have a broad white band beneath the suture, which is ex- 

 tended to the base of the shell ; others are dark fuscous, with a narrow white line 

 beneath the suture ; the latter agree with the figure of P. nodosa in Chemnitz. 



t P. nucleola Pse. Mss., Mus. Godeff. Cat., v. p. 92, 1874. Coll. Pse. Moorea, 

 Garr. This shell equals short depauperated specimens of P. spadicea. 



P. OBESA Pse., A. J. C, iii. p. 223, pi. 15, f. 12, 1867. Islands Fortuna and 

 Vavao, Graff. The figure of Mr. Pease resembles a Bulimus ; the type specimen 

 in the Pease collection is lost. 



t P. Otaheitana Brug., Ency. Method., i. p. 347, No. 84, 1792. Tahiti. The 

 original description of this shell calls for " a heavy brown sinistral shell, oblong, 

 ovate, perforate, aperture semiovate, unidentate." Mr. Garrett informs me that 

 this variety occurs near the old anchorage, and is probably the original type. 

 Large quantities of this shell exhibit all the varieties merging into each other. 

 Small dextral specimens are often confounded with P. affinis. On the other hand, 

 large, well-developed sinistral specimens, with or without a dentile, as P. Reeve-
