The above may be distinguished from P. gibba (Terr.), which 

 occurs at the same locality, in being of smaller size, last whorl 

 not inflated, and in its color. 



Partula Brazieri, Pse. Plate 9. fig. 5. 



T. dextrorsa, umbilicata, conico-elongata, recta, solidiuscula, 

 striis confertis transversim distincta notata, nitida, pallide stra- 

 minea, prope basin, pallide fusco obsolete bifasciata ; anfr. 5 

 convexis, ultimus J longitudinis testae fere aequans ; sutura im- 

 pressa,. simplici ; apertura vix obliqua, ovalis ; perist. album, in- 

 crassatum, convexum, breviter et sequaliter expansum ; columella 

 superne late dilatata. 



Alt. 22J, diam. 12 mill. ; ap. 9 mill, longa, G mill. lata. 



Hab. in Insula Tutuila (Brazier). 



This species was collected by Mr. Brazier at the above locality. 

 It is of the type of P. conica, (Gld.) and canalis, Mouss. The 

 shell is straight, elongate dextral, whorls convex, marked trans- 

 versely by the usual fine striae and longitudinally by lines of 

 growth. The color is pale yellow, with two indistinct bands of 

 pale brown encircling the last whorl near its base. The lip is 

 callous and but slightly expanded ; columella widely dilated 

 above, its callosity extending some distance over the wall of the 

 aperture. 



Genus HYALOPSIS, Pse. 



Testa purpaeformis, callo nitido obducta ; perist. simplex, vix 

 incra"ssatum, margine columellari integro, canali verticalis ad in- 

 sertionum marginis dextri. Apertura circularis. 



The above genus is another link connecting the several genera 

 Pupina, Registoma and Ottilia. 



I quite agree with Mr. Dohrn that they should be united, but 

 that the several groups should retain their names as subgenera. 



Hyalopsis tumida, Pse. Plate 9, fig. 6. 



T. dextrorsa, oblique ovata, nitida, pellucida, laevigata, fulvo- 

 cornea ; anfr. 5, rotundato-convexis tumidis; apice vix obtusa ; 

 sutura filo-marginata ; perist. circularis, vix incrassatum, album. 



Alt. 7J, diam. 5 mill. Hab. Insulis Salomonis. 



Shell dextral, obliquely ovate, shining, smooth, pellucid, yel- 

 lowish horn color ; whorls five, roundly convex, somewhat swol- 

 len ; apex obtuse, suture narrowly marginate ; peristome circular, 

 slightly callous, white. 



Collected at the above locality by Mr. John Brazier.
