摘　　要：作者在贵州省镇宁布依族苗族自治县境内采得陆生贝类标本一批 ,经鉴定得喇叭螺属 2种 ,即 :天星桥喇叭螺 ,新种Boysidia (Bansonella)tianxingqiaoensisLuo ,ChenetZhang ,sp .nov .;黄果树喇叭螺 ,新种Boysidia(Boysidia)huangguoshuensisLuo ,ChenetZhang ,sp .nov .对新种的形态进行了详细描述 。In the present paper, two new species of Pupillidae are described. The material studied was collected by authors from Guizhou Province, China, August 23, 1997. Type specimens are deposited in the Institute of Zoology, Chinese Academy of Sciences.1 Boysidia (Bansonella) tianxingqiaoensis Luo,Chen et Zhang,sp. nov. (Figs.1 4) Holotype length 2.17?mm, breadth 3.22?mm; length of aperture 1.28?mm, breadth of aperture 1.33?mm; collected from Tianxingqiao Town, Zhenning Bouyeizu Miaozu Zizhixian (26°N, 105°7'E), Guizhou Province, Aug. 13, 1997. Paratypes 29 specimens, length 2.06 2.22?mm, breadth 3.11 3.39?mm; length of aperture 1.28 1.44?mm, breadth of aperture 1.33 1.44?mm; the same locality and date as holotype. Shell little, thick, lustre, conic. Whorls 312, moderately convex, spire depressed conical, embryo whorls(1 2) increased slowly, smooth, the body whorl very inflated, and slants downward, with a keel shaped at its the periphery. Shell deep yellow brown in colour, and with innumerable slender and dense growth lines and spiral lines, silky. Apex blunt, suture deep. Aperture elliptical, bell formed, very expanded and reflexed, thick, the peristome separated from body whorl, and not oblique, but aperture nearly parallel to body whorl, with 5 teeth; angular and parietal lamellae united into 1 big lobed lamella, 1 nipple formed upper palatal fold, 1 long pillar formed lower palatal fold, 1 small nipple formed basal fold, 1 flake formed columellar lamella. This new species very resembles Boysidia (Bansonella) plicidens (Benson, 1849), but differs from the latter by the shell with 512 whorls(length 2.00?mm, breadth 1.50?mm) in large size, the latter with 5 whorls, 9 palatal folds, and 3 parietal lamellae.2 Boysidia (Boysidia) huangguoshuensis Luo,Chen et Zhang,sp. nov. (Figs.5 7) Holotype length 3.17?mm, breadth 2.20?mm; length of aperture 1.22?mm, breadth of aperture 1.06?mm; collected from Huangguoshu Town (25°9′N, 105°6′E), Zhenning Bouyeizu Miaozu
