No. 5. — Observations on the Species of the Genus Partula F^r., 

 ivith a BiUiographical Catalogue of all the Species. By Wil- 

 liam Dell Hartman, M. D. 



The genus Partula, proposed by Baron F^russac, in 1819, at the 

 present time embraces numerous species, encumbered by synonyms and 

 manuscript names. This catalogue has been prepared with a view to 

 indicate the former, as well as to eliminate and define the status of the 

 latter, hoping in the future to be enabled to indicate a full and correct 

 synonymical catalogue of the genus, together with a new arrangement 

 of the species. Prior to his decease, the late William Harper Pease was 

 engaged in the preparation of a monograph of the genus Partula, in 

 which he designed describing and figuring all his new species. In an- 

 ticipation of this work, he freely distributed his manuscript and pub- 

 lished species amongst institutions and private collections. Since that 

 time the names of many of the former have been incorporated into 

 printed catalogues, thereby creating confusion in synonymy, and hence 

 it was deemed proper to notice all such in these pages. The large col- 

 lection of Mr. Pease having, by purchase, passed into the possession of 

 the Museum of Comparative Zoology, Cambridge, through the favor of 

 Professor Agassiz of that institution I have been enabled to trace his 

 published and manuscript species with a considerable degree of accuracy. 

 I have also been favored by Andrew Garrett, Esq., of Huaheine, (who 

 collected for Mr. Pease, and was familiar with all his species,) with all 

 the species and varieties of Mr. Pease from the islands the maps of 

 which accompany this paper. In the year 1864, the Rev. P. P. Car- 

 penter published in the proceedings of the Zoological Society a catalogue 

 of Partulse with synonyms, chiefly those of IMr. Pease, which contains 

 numerous incorrect determinations. Mr. Gloyne has also published a 

 partial list of Partulse in the Quarterly Journal of Conchology, which 

 contains several synonymical inaccuracies. In the proceedings of the 

 Zoological Society for 1871, the late William H. Pease published a cata- 

 logue of the Polynesian Partulse, numbering over sixty species. In this 

 list he has omitted twenty-seven species, which embraced*.all his manu- 

 script, together with a few of his published species. These omissions, it
