EuLiMA (Subtjlaria) fuscopunctata. (Plate XXI. fig. 18.) 



Testa minuta, subulate, pellucida, punctis fuscis irregulariter 

 notata, nitida ; spira acuminata, apice mediocriter acuto, con- 

 voluto ; anfractus 9, tres apicales convexi,ceeteri subplani, elon- 

 gati, sutura obliqua sejuncti ; apertura elongata, ovatu, superne 

 anguste acuminata, longit. totius 5 paulo supernns ; columella 

 ■ obliqua, leviter incrassata at reflexa. 

 Longit. 2| millim., diam. | ; apertura | longa, \ lata. 

 This minute shining little species is remarkable for the minute 

 brownish scattered dots, which do not appear to be arranged in 

 regular series. 



Amaurella canaliculata. (Plate XXIII. fig. 27.) 



Testa parva, tenuis, hijalina, umbilicata, ovato-turrita ; anfr. 7, 

 convexi, ad sutur am profunda canaliculati, leaves ; apertura ovata, 

 paulo obliqua, longit. totius 3 (equans ; peristoma tenue, mur- 

 gine columellari leviter dilatato, inferneque suheffuso. 

 Longit. 3 millim., diam. If. 



This remarkable shell has the first three or four whorls narrow in 

 proportion to the others, so that the spire has a suddenly contracted 

 appearance towards the top. The umbilicated base, smooth surface, 

 and channelled suture well distin^^uish this species. In describing 

 the genus Amaurella, Adams states incorrectly that it is " imperforata," 

 for the typical species A. japonica is distinctly perforate, although 

 more narrowly than that now described. 



CioNiscus TjNicus (Moutagu). 



Hab. British Islands, west coasts of France, and some parts of 

 the Mediterranean. 



The three specimens of this beautiful shell from St. Helena have 

 the whorls the least trifle shorter than British specimens with which 

 they have been compared, but agree in all other respects. 



AcLis angulata. (Plate XXIII. fig. 28.) 



Testa minuta, elongata, turrita, alba ; anfr. 6, primi duo magni, 

 convexi, Iceves, cceteri superne oblique declives, in medio acute 

 carinato-angulati, infra unguium contracti, lineis incrementi 

 conspicuis, elevatis, confertissimis, regularibus, sculpti ; anfr. 

 ultimus ad peripheriam obtusissime rotunda angulatus ; apertura 

 obliqua, irregulariter ovata ; peristoma continuum, haud incras- 

 satum, supra unguium, prope suturam, leviter sinuatum. 



Longit. 2 millim., diam. |. 



This little species is remarkable for its angular whorls, the regular 

 close-set raised lines of growth, and large apex. 



AcLis siMiLLiMA. (Plate XXIII. fig. 29.) 



Testa minuta, gracilis, alba, nitida, pellucida; anfractus normales 7, 

 convexiusculi, sutura obliqua profunde sejuncti ; iiucleus magnus, 

 convolutus, elevatus ; apertura lata, inverse subauriformis ;
