54 FULTON : LAND SHELLS I'KO.M GELI ISLAND. 



5.— Albersia subsphoeriea, n. sp. 

 Fl. i\', figs. 8, g. 



Shell subglobose, moderntely solid, imperforate, medium dark brown widi 

 a darker narrow spiral band bordered below by a similar one of a yellowish 

 colour situated a little above the periphery of last whorl and continued for a 

 short distance at the suture; covered throughout I y oblique rows <'f close- 

 set hair-scars ; whorls 4)5, moderately convex, rapidly increasing, last shortly 

 descending ; aperture subcircular, outer band showing faintly through : peris- 

 tome slightly expanded, broadened at point of insertion, a cir(um-uml)ilical 

 dark patch, inner columellar edge white, ending abruptly below with a rather 

 acute angular projection. 



Maj. diam. 24; alt. 17 millim. 



Near .-1. ji^i-iphji-oni^ia, Strul)ell, but slighll)' more globose, the whorls 

 are more clo.sely coiled and the h lir-scars are more numerous. I'he lines of 

 growth in jiseiu/oruras-ia are rather conspicuous at the suture, giving it a some- 

 what crenulated appearance, whereas in subxjthorn'rn the suture is simple. 



Of the three specimens before me one cU)es not show the tooth-like 

 jjrojection noted in the description of the type, and the third specimen only 

 shows it \ery faintly. 



6.— Leptopoma gebiensis, n. sp. 



ri. iv, figs. 10, II. 



.Shell umbilicated, subconic, moderately thick, colouration variable, generally 

 whitish ground with reddish-brown spiral bands which are (jften more or less 

 interrupted, last whorl with eight white striae, (jne at the peripher\', four 

 above and three below, between these are numerous much finer striae ; 

 whorls 5^,, moderately convex, last rather acutely keeled in front : a|K'rture 

 circular, spiral striae showing through the interior ; peristome expanded, 

 double (in adult specimens), inner edge more or less exserted, white, colum- 

 ellar portion narrow, broadening at lower part : operculum normal. 



Maj. diam. 17; alt. 15 millim. 

 14; „ 12 „ 



Similar in form to L. rreni/ahn', Strubell, but that species is much 

 smoother, the peristome is less oblique and the last whorl is rounded in front, 

 not moderatelv keeled as in (leliien^is.
