中文摘要:
      伞形琥珀螺(Succinea daucina),最早由Pfeiffer在1854年报道。本文采用形态解剖学的方法对采自新疆乌鲁木齐南山西白杨沟(43°24.674′N,87°08.620′E,海拔1 785 m)的伞形琥珀螺进行了观察。测量并解剖了贝壳颜色分别为黄棕色和浅黄色的性成熟个体各10只,绘制了内部解剖图,应用电子扫描显微镜对两种壳色各3只个体齿舌、颚片的显微结构进行了观察和拍摄记录。伞形琥珀螺贝壳为长卵圆形,中等大小,壳高10.06 ~ 12.90 mm,壳宽6.28 ~ 8.56 mm,壳质薄,有3 ~ 3.5个螺层。其齿式为16-21:10-13:1:10-13:16-21,中央齿三锥型,侧齿和边缘齿双锥型。软体乳白色,色素点少。储精囊一个,蛋白腺、前列腺大,阴茎管状,约3/4被阴茎鞘包裹。两种壳色标本的齿舌、颚片及内部解剖特征相同,为同一种,即伞形琥珀螺。
英文摘要:
      Succinea daucina was originally described by Pfeiffer in 1854 from Calcutta, India. In this paper, S. daucina collected from western Baiyanggou, Urumqi, Xinjiang (43°24.674′N, 87°08.620′E, altitude 1 785 m) was observed using anatomical methods. Two different colored shells were found in specimens, yellowish-brown and light yellow. Ten adult specimens of each colored shell were measured and dissected. Drawings of the internal structures were made with the aid of photographs taken using a D700 Nikon digital camera. Radula and jaw of three specimens of each different colored shell were photographed using a LEO 1430VP scanning electron microscope. The results showed that shell of S. daucina was elongate-ovate, medium-sized (10.06﹣12.90 mm in height, 6.28﹣8.56 mm in width), very thin, with 3﹣3.5 whorls (Fig. 1). Radular formula was 16-21:10-13:1:10-13:16-21. Central teeth were tricuspid, and lateral teeth and marginal teeth were bicuspid (Fig. 2). Body of living and alcohol-preserved specimens was cream-white with a small amount of black pigmentation (Fig. 3a). Receptaculum seminis was one. Albumen gland and prostate gland were big. Penis was thick-walled and tubular, and about 3/4 was enclosed by penial sheath (Fig. 3b, c). Two different colored shell specimens were one species, S. daucina, due to their same radula, jaw and anatomical characters. Voucher specimens were deposited in the College of Life Science and Technology, Xinjiang University.
