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



Testa minuta, subulata, pellueida, punetis fuscis irregulariter 

 notdta, nitida ; spira acuminata, apice mediocriter acuta, con- 

 voluto ; anfractus 9, tres apicales co7ivexi, ereteri subplani, elon- 

 gati, sutura obliqua sejuficti ; apertura elongata, ovata, stcperne 

 anguste acuminata, longit. totius ^ paulo supernns ; columella 

 obliqua, leviter incrassata et 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. 



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



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

 convexi, ad suturamprofunde canaliculati, Iteves ; apertura ovata, 

 paulo obliqua, longit. totius 3 cequans ; peristoma teiiue, mar- 

 gine columellari leviter dilatato, inferneque subeffuso. 

 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 distini>uish this species. In describing 

 the genus Amaurella, Adams states incorrectly that it is '■'■ imperforata,'^ 

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

 more narrowly than that now described. 



CiONiscus uNicus (Montagu). 



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, cteteri superne oblique declives, in medio acute 

 carina to-angulati, infra unguium contracti, lineis incrementi 

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

 ultimus ad periplieriam obtusissime rotunde angulatus; apertura 

 obliqua, irregulariter ovata ; peristoma continuum, haud incras- 

 satum, supra angulum, 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. 2y.) 



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

 convexiusculi, sutura obliqua profutide sejuncti ; nucleus mugnus, 

 convolutus, elevatus ; apertura lata, inverse subauriformis ;
