The very elegant Helix. Shell rather largely umbi- 

 licatcd, flatly orbicular, very depressed, rather trans- 

 parent, pale straw-coloui', obli(iucly very finely pli- 

 cately striated ; whorls seven, flattened, last whorl 

 very sharply keeled, keel white, peculiarly finely ser-

 gularly ovate ; lip rather thickened, reflected, white, 

 margins approximating.

This very delicate species is characterized in a manner 

 extremcily curious. The finely plicated stria^ become deve- 

 loped at their extremity ou the keel into a fine serrated 

 fringe, which is seen in the place of the suture throughout 

 the spire.

The New Ireland Helix. Shell umbilicated, globoscly 

 depressed, keeled, obliquely striated in a wrinkled 

 manner, thin, fulvous, encircled with a red line at 

 the keel ; whorls six, rather convex, the last more 

 convex and smoother at the base, obsoletely decus- 

 sated with concentric lines ; aperture lunar, shining 

 within ; lip straight, obtuse, columellar margin rather 

 thickened.

The red-brown line which encircles this species at the 

 periphery, is faintly seen in the sutures of the spire.

The resplendent Helix. Shell slightly iimbilicated, 

 depressed, very smooth, shining, thin, pellucid, yel- 

 lowish-homy ; spire but little prominent ; whorls six 

 to seven, rather convex, increasing slowly, the last 

 regularly enlarged, convex at the base, deeply im- 

 pressed in the middle ; aperture almost vertical, de- 

 pressed, broad, lunar : lip simple, acute, columellar 

 margin descending very oliliqucly.
