1889.] SPECIES OF LAND-SHELLS. 



79 



Var. y. Hand malleata, fusco sparsim radiata, sed non maculata ; 

 striis conspicuis, rugosis. 



Long. 86, maj. diatn. 44 7nill. 



Hab. Catamarca, Ancles Peruvise. 



The typical shell has a peculiarly malleated surface, and the 

 indentations are rendered conspicuous by the brown markings. The 

 variety, wanting these characters, presents so different an appearance 

 that it might be taken for a distinct species. There is, however, but 

 little difference in the form, the colouring of the mouth is the same, 

 the brown ravs also are similar in colour and disposition. The 

 longitudinal striae are closer and more regular, taking the place of 

 the irregular indentations characteristic of the typical form. 



The two shells form part of the collection of Mr. S. J. Da Costa, 

 and there is a specimen of each variety in the National Collection at 

 South Kensington. 



6. AcHATiNA BARRiANA, u. sp. (Plate LVI. fig. 2.) 



A. testa ovato-conivn, tenuis, cornea, maculis parvis fuscis ad 

 siituram et ad peripheriam tceniata, maculis parvis alivlis hie 

 iUicfloccata ; spira conica, apice ohtusa ; anfr. G, convexiuscu/i, 

 supremi Iteves, sequentes confer tissime lirati, liris rugosis, 

 ultimus spiram superans, infiatus ; apertura ampla, vix obliqua ; 

 peristoma simp/ex, tenue ; columella leviter infiexa, oblique 

 truncata. 

 Long. 43, diam. 23; apert. longa 24, lata 14 mill. 

 Hah. Calabar, Africa ? 



A light shell of elegant form, sculptured with very fine close 

 corrugated ridges. The body-whorl is sprinkled with small white 

 flake-like spots. 



I have only seen two specimens of this species ; they were found 

 in company with Perideris auripic/mentum, and are probably from 

 the same locality. 



7. AcHATiNA SMiTHi, n. sp. (Plate LVI. fig. 3.) 



A. testa ovato-turriia, tenuis, pellucida, cornea, nitida, strigis 

 longitudinalibus numerosis undulatis pallidis pieta ; spira 

 elatiuscula, turrita, apice oltusa ; anfracivs 6, convexi, spiraliter 

 minutissime sed densissime striati, sutura impressa, haud crenu- 

 lata ; anfr. ultimus spiram paiilo superans, leviter inflatus ; 

 apertura verticalis, sinuato-ovalis ; peristoma simplex ; colu- 

 mella recta, oblique truncata. 

 Long. 30, diam. 1.5; apert. longa 14, lata 7 mill. 

 Hab. Calabar, Africa? 



A delicate pellucid species ; a true Achatina, but approaching in 

 form and texture some of the species of Glandina. The longitudinal 

 streaks are faint, but numerous and pretty regular ; the spiral striae 

 seen through a lens are exceedingly fine and close. 



Of this species I have only seen a single specimen ; its habitat is 

 uncertain, but it is probably from the same locality as A. barriana.
