and must also be allied to N. lupinus, Desh. The whorls are 

 closely appressed at the suture, and the network coloring is much 

 like that on the bands of Conus ammiralis.

Allied to S. maculata, Quoy, but the spire is less elevated, the 

 aperture is more rounded, and above all, it is characterized by 

 the plain white lunate area adjacent to the columella. 



Stomatella tumida. Testa subglobosa, ampullacea, tenuis, 

 nitida, cinereo-olivacea, prope suturam albido et rufo seriatim 

 maculata et lineolis sagittatis vittata, subtus flavescens, sulcis 

 remotis cincta, sulcis basalibus fusco-articulatis : spira anfr. 

 4 tumidis : apertura circularis intus margaritacea ; labro acuto, 

 albo ; columella revoluta, callo copioso, erecto, albo-striato mar- 

 ginata. Long. Lg- ; lat. £•; alt. | poll. Hab. China Seas, 

 Moluccas. 



Distinguished by its globular form, shining surface, peculiar 

 coffee-colored ground with delicately painted feathery ridges and 

 the large white erect columellar callus. It accords with the 

 figure in Chemnitz, named Turbo papyracea, but that shell is 

 described as perfectly smooth. 



Ampullaria columellaris. Testa ponderosa, imperforata, 

 rhomboidali-ovalis, nitida, sed sub lente argute reticulata, flavo-

 lari, prselonga, cylindrica, contorta ; labro fiavido, evaso ; fauce 

 castaneo. Long. 2^ ; lat. 2 poll. Hab. Province of Maynas, 

 Peru. 



Remarkable for its solidity, its elongated form, its want of 

 umbilicus, and the presence of a columella like that of the buli- 

 moid helices. 



Amnicola badia. Testa minuta, elongata, ovato-turrita, badia : 

 spira acuta, apice erosa, anfr. 5 convexiusculis, ultimo vix angu-
