3. Guppya hallucinata, n. sp. (fig. 7). 



Testa angustissime perforata, conoidea, ad apicem obtusa, corneo-fusces- 

 cens, nitida ; anfr actus 5 convexi, sutura profunda sefuncti, lineis incre- 

 menti confertis microscopicis striati, lente accrescentes; ultimus postice ad 

 peripheriam leviter angulatus, subtus concentrice tenuiter striatus ; 

 apertura oblique lunata ; peristoma tenue, margine columellari supeme 

 leviter reflexo. Dia?n. maj. 3 ?um., alt. 3. 



Very like G. semen-lini, but rather more elevated in the spire and 

 with the upper surface of the whorls merely microscopically striated 

 with lines of growth and not cancellated. The body-whorl also is less 

 sharply keeled. 



Luntia, n. g. 



Testa elongata, gracilis, imperforata, columella tortuosa, antice oblique 

 truncata, callo reflexo induta, labro supeme prope suturam conspicue 

 sinuato, infra sinum leviter incrassato. 



This genus of Stenogyridae is allied to Subuliua, but is dis- 

 tinguished by the sinus at the upper part of the labrum. The following 

 is the only species at present known. 



4. Luntia insignis, n. sp. (fig. 8). 



Testa parva, elongata, gracilis, imperforata, alba, ad apicem mam- 

 millata; anfractus 7, supremi duo magni, Iceves, cceteri convexi, costellis 

 tenuibus arcuatis inferne plus minus desinentibus, supra, ad suturam 

 productis, instructi ; apertura parva, inverse aurifor?nis ; columella 

 arcuaia, inferne torta, oblique truncata, callo albo crassiusculo, supeme 

 labro juncto, induta ; labium in medio prominens, supra valde sinuatum, 

 infra sinum leviter incrassatum. Longit. 5^ ;;/;//., diam. 1^; apertura 

 1 A longa, 1 lata. 



The slender cost^e, being produced above, give the suture a crenu- 

 lated appearance, and below, as a rule, they do not extend quite 

 across the whorls. The columella!" callus is very thick, the upper part 

 almost forming a tubercle.
