This part includes the account of Anonchotaenia globata (LINSTOW, 1879) and its embryo, and of Mathevotaenia ornithis sp. nov.--Anonchotaenia globata is know to be a parasite of Passer domesticus in foreign countries. The writers record it for the first time in India in this bird. This species is also known from other birds, but not so far recorded even in other birds in India. VOGE and DAVIS (1953), METTRICK (1958) and MAHON (1958) previously studied this species. The present study contributes additional data to the morphology of this species. Variations in the number of testes, extent of cirrus sac, and position of genital pore have been recorded. A definite neck has been found. Calcareous corpuscles, occurrence of which is not on record in this species, have been found in the present material. Paruterine organ, to which previous workers paid scant attention, has been studied in detail. It is a complex three-layered structure. Eggs undergo development upto the formation of embryos while they are still in the uterus, and subsequently they all pass into the paruterine organ which is found teeming with embryonated eggs. Eggs are quite characteristic in shape. Two coverings are found around the embryos: the outer one, the shell capsule, is spindle-shaped and cornuted; the hexacanth enclosed in a membrane is housed in the dilated middle part of the shell capsule. Hexacanth is an elongated structure with a dilated middle part and not a uniform width. Hence the term "nematodiform" embryo used for it is rather inappropriate. Three pairs of hooks are present in the dilated middle part of the embryo. WOODLAND (1929) and METTRICK (1958) denied the existence of the hooks.--Mathevotaenia ornithis sp. nov. is the first species of the genus Mathevotaenia AKHUMIAN, 1946 that has been described from an avian host, other species are known from mammalian hosts. Amongst the mammalian species, the present form comes close to Mathevotaenia deserti (MILLEMANN, 1955) and M. hardoiensis JOHRI, 1961, but differs from either in several features. This species is chiefly characterized by the number and distribution of testes, bilobed ovary, genital ducts passing between the excretory canals, vitellarium V-shaped, and cirrus sac extending aporally beyond the excretory canals. Besides, the bearing of the receptaculum seminis on the taxonomy of the genera Mathevotaenia AKHMUIAN, 1946 and Atriotaenia SANDGROUND, 1926 has been discussed, and an amendment in the generic delineation has been suggested for these genera.--Systematic position of Mathevotaenia antrozoi (VOGE, 1954) YAMAGUTI, 1959 has been discussed and the species has been assigned to Atriotaenia.
这部分内容包括球形无钩绦虫（林斯托，1879）及其胚胎，以及新种鸟类马特绦虫的描述。——已知球形无钩绦虫在国外是家麻雀的寄生虫。作者在印度首次记录到该绦虫寄生于这种鸟类。该物种也见于其他鸟类，但在印度的其他鸟类中尚未有记录。沃格和戴维斯（1953年）、梅特里克（1958年）和马洪（1958年）此前曾对该物种进行过研究。本研究为该物种的形态学提供了更多数据。记录了睾丸数量、阴茎囊范围和生殖孔位置的变异情况。发现了明确的颈部。在当前材料中发现了钙质小体，该物种此前并无相关记录。前人较少关注的子宫旁器官已得到详细研究。它是一个复杂的三层结构。卵在子宫内发育直至形成胚胎，随后它们全部进入充满胚胎化卵的子宫旁器官。卵的形状很有特点。胚胎周围有两层包膜：外层的壳囊呈纺锤形且有角状突起；包在膜内的六钩蚴位于壳囊膨大的中部。六钩蚴是一种中部膨大的细长结构，宽度并不均匀。因此，用于描述它的“线虫形”胚胎这一术语并不恰当。胚胎膨大的中部有三对钩。伍德兰（1929年）和梅特里克（1958年）否认有钩的存在。——新种鸟类马特绦虫是1946年阿克胡米安的马特绦虫属中首个从鸟类宿主描述的物种，其他物种见于哺乳动物宿主。在哺乳动物物种中，该物种与沙漠马特绦虫（米勒曼，1955年）和哈多伊马特绦虫（乔里，1961年）相近，但在一些特征上有所不同。该物种的主要特征是睾丸的数量和分布、分叶状卵巢、生殖管道在排泄管之间通过、卵黄腺呈V形以及阴茎囊向口侧延伸超过排泄管。此外，还讨论了贮精囊对1946年阿克胡米安的马特绦虫属和1926年桑德格伦德的阿特里绦虫属分类学的影响，并对这些属的属级划分提出了修正建议。——讨论了1959年山口的安特罗伊马特绦虫的系统地位，并将该物种归入阿特里绦虫属。
