3 morphologically distinct hemolymph cell-types, Types I, II and III, were found by light and electron microscopy of hemolymph from the land slug, Incilaria bilineata. In addition, vast numbers of the platelet-like structures were present in the collected hemolymph. Type I cells were macrophage-like, Type II cells were lymphocyte-like and Type III cells were fibroblast-like. Among these hemolymph cells, only Type I cells could recognize foreign materials and phagocytose them. Type I cells, whether from circulating hemolymph or from the heart-kidney region (regarded as a hemopoietic organ), could be maintained for only 4 d in cultivation because the cells gradually divided within 3 or 4 d. Thus, the platelet-like structures appear to be derived from Type I cells, which readily fragmentize and function by clamping onto foreign materials.
通过对双线嗜黏液蛞蝓血淋巴进行光学显微镜和电子显微镜观察，发现了3种形态不同的血淋巴细胞类型，即I型、II型和III型。此外，在采集的血淋巴中存在大量血小板样结构。I型细胞类似巨噬细胞，II型细胞类似淋巴细胞，III型细胞类似成纤维细胞。在这些血淋巴细胞中，只有I型细胞能够识别并吞噬异物。I型细胞，无论是来自循环血淋巴还是心脏-肾脏区域（被视为造血器官），在培养中只能维持4天，因为细胞在3或4天内会逐渐分裂。因此，血小板样结构似乎源自I型细胞，I型细胞很容易破碎并通过附着在异物上来发挥作用。
