DESCRIPTIONS OF FOUR SPECIES OF LAND SEELLS IN- 

 HABITING THE PAPUAN ISLANDS. 



BY THE LATE W. HARPER PEASE. 



* 



Partula turricula, Pse. 



T. elongata, turricula, solida, sinistror.sa, rimato-perforata, 

 nitida, laevigata, striis incrcmentis tenuiter notata, lutescens, 

 strigis saturatioribus indistincte radiata ; spira turricula, acutius- 

 cula|anfr. 5J, plano-convexi, ultimus spira brevior, oblique pro- 

 ductus ; columella verticalis, valde callosa, superne late dilatata, 

 prsecipue supra umbilicum, transverse subsulcata ; apertura ob- 

 liqua, oblonga, postice oblique truncata ; perist album, callosum, 

 expansum et reflexum, postice vix sinuatum. 



Long. 20, diam. 10 mill. Hab. (?) N. Hebrides. 



The habitat of the above species is doubtful. From its ap- 

 proaching P. Macgillivrayi, Pfr., and Caledoniea, Pfr., inhabiting 

 the New Hebrides, and having lately received specimens from 

 Dr. Jas. C Cox, with other species from that group of islands, 

 there is little doubt but that locality is the correct one. 



It differs from the species mentioned above in being smaller, 

 more slender, "sinistral," smooth, without any trace of trans- 

 verse striae, and last whorl produced. 



Partula concinna. Pse. 



T. compresse umbilicata, conico-ovata, tenuiscula, conferte et 

 distincte spiraliter striata, pallide fulvescens, aut albescente, 

 strigis saturatioribus radiata, apicem interdum rufescente; spira 

 acutiuscula, brevis, conica ; anfr. 5, convexiusculi ; ultimus spiram 

 sequans ; sutura interdum submarginata, columella fere verticalis, 

 nodosa, superne dilatata ; apertura subverticalis, ovalis ; perist 

 album, incrassatum, convexum, expansum vix reflexum.
