11. Leptopoma woodfordi, n. sp. (Plate LVI. fig. 13.) 



L. testa profunde umhilicata, f/lohoso-conica, tenuis, pellucida, 

 albida, spiraliter lirata, oblique striata, ad peripherium 

 carinata ; spira conica, paruin elevata, acutiuscula ; aiifractus 

 5, coiivexi, rotundati ; anfr. ultimus injlatus, infra Icevigatus, 

 convexus ; apertura ampla, suhcirculai-is ; peristoma tenue, ex- 

 pansum, maryine columellari aiigusto, extus angulato. 

 Diam. 21, alt. 18 mill. 

 Hah. Guadalcanar, Ins. Salomonis. 



A whitish, pellucid, spirally ridged species with rather a large, 

 nearly circular mouth and thinly expanded lip. The columellar 

 margin is narrow, with an angle on the outside. One of the 

 specimens in the National Collection is 23 millim. in diameter, 

 wliile another adult specimen does not exceed 1.5 millim. 



12. Cyclostoma hanningtoni, n. sp. (Plate LVI. fig. 14.) 

 C. testa umbilicata, yloboso-conica, solidiuscula, undique spiraliter 



multilirata, striis incrementi decussata, sordide albida, griseo- 

 radiata, fusco bifnsciata ; spira breviter conica, apice rufo-fusca, 

 acutiuscula ; anfractus 5, convexi, rotundati, ad suturam minu- 

 tissime crenulati; anfr. ultimus brevis, basi rolundatus ; apertura 

 leviter obliqua, subcircularis, fauee fusca ; peristoma tenue, 

 leviter expansum, crenulatutn, album. 

 Diam. 24, alt. 23 mill. 

 Hab. Africa sequatorialis. 



This species is allied to C insulare (Pfr.), but it is considerably 

 larger than any specimen I have seen of that species, the body- 

 whorl is larger in proportion to the spire, and the spiral ridges are 

 sharper and more prominent. The specimen, at present unique, is 

 in the collection of Mr. S. J. Da Costa. 



13. BunMUS (Mesembrinus?) bowkeri, n. sp. (Plate LVI. 



%-5.) 



B. testa subrimata, ovato-conica, tenuiuscula, longitudinaliter 

 rugoso-striata, sulcis transversis irregularibus plus minusve 

 cancellata, dilute purpurea, versus apicem fusca ; spira elato- 

 conica, apice obtusiuscula ; sutura impressa,vix crenulata ; an- 

 fractus 5, leviter convexi ; anfr. idtimus spiram paulo superans, 

 leviter injlatus, obliquiusculus, basi rotundatus, vix attenuatus ; 

 apertura obliqua, ovalis, intus aureo-fusca ; peristoma simplex, 

 rectum, margine dextro arcuato, albo ; columellari fusco, superne 

 tenuiter effuso. 

 Long. 20, maj. diam. 1 1 mill. 



Hab. Somerset (East), Cape Colony. Forest about 3000 feet 

 above sea-level (^Col. Bowker). 



A species having very much the form and appearance of a Succinea, 

 Several specimens presented to the National Collection by Colonel 

 Bowker present but little variation in form and colour, but in some 

 specimens the spiral grooves are much more marked than in others ; 

 in one or two they are almost confined to the penultimate and 

 antepenultimate whorls.
