Obs. — I agree with Mr. Garrett in combining all these variable 

 shells from Moorea under one species, but I doubt if they = 

 lineata Lesson. Suturalis and strigosa, in the Cumingian Collec- 

 tion, are only varieties of the Moorea shell; stenostoma and 

 suturalis were described by Pfeiffer from examples in the British 

 Museum, which are only varieties of alternata and vexillum 

 Pease.

Obs. — Mr. Garrett very properly remarks, " this is truly a 

 protean species." Of this fact I have been cognizant since I 

 examined the duplicate collection of the late Mr. Pease. In six 

 pints of duplicates from Moorea the connection between the 

 varieties was readily traceable ; on comparison " there is no 

 difference between examples of these shells and those of spadicea 

 in the British Museum, except that some are a trifle shorter." 

 Morch's habitat, Fiji Isles, for taeniata, is probably an error, as 

 his examples " were purchased of a whale fisher." Pfeiffer, in 

 the last edition of his Catalogue of- Partula, says peraffinis Pse. 

 MS. = elongata Pse.
