L. testa profunde umbilicata, globoso-conica, tenuis, pellucida, albida, spiraliter lirata, oblique striata, ad peripheriam carinata; spira conica, parum elevata, acutiuscula ; anfractus 5, convexi, rotundati; anfr. ultimus inflatus, infra Icevigatus, convexus ; apertura ampla, subcircularis; peristoma tenue, expansum, margine columellari angusto, extus angulato. Diam. 21, alt. 18 mill. LLab. 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, while another adult specimen does not exceed 15 millim. 12. C Y C L O S T O M A H A N N I N G T O N I , n. sp. (Plate LVI. fig. 14.) C. testa umbilicata, globoso-conica, solidiuscula, undique spiraliter multilirata, striis incrementi decussata, sordide albida, griseo-radiata, fusco bifasciata ; spira breviter conica, apice rufo-fusca, acutiuscula ; anfractus 5, convexi, rotundati, ad suturam minu-tissime crenulati; anfr. ultimus brevis, basi rotundatus; apertura leviter obliqua, subcircularis, fauce fusca; peristoma tenue, leviter expansum, crenulatum, 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. B U L I M U S (MESEMBRINUS?) BOWKERI, n. sp. (Plate LVI. fig. 5.) B. testa subrimata, ovato-conica, tenuiuscula, longitudinaliter rugoso-striata, sulcis transversis irregularibus plus minusve cancellata, dilute purpurea, versus apicem fusca ; spira elaio-conica, apice obtusiuscula ; sutura impressa, vix crenulata ; anfractus 5, leviter convexi; anfr. ultimus spiram paulo superans, leviter inflatus, obliquiuscuius, 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. 11 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. |
