Caudal extremity twisted in one spiral turn and with wide alae. Drasche states that the tail has 2 pairs of preanal papillae and has 2 postanal papillae but his figure (fig. 275) shows 4 pairs of preanal and 2 pairs of post- anal; the right spicule is short and thick, and the left is long and alate with its tip barbed like a fishhook.

Female 7 to 15 mm. long by 300/w wide. Anus near caudal ex- tremity. Vulva in posterior part of body. Life history.—Unknown; probably involves intermediate stages in some other hosts. Distribution.—South America (Brazil). Seurat (1915) has suggested that this species is rather close to Hartertia obesa. It is possible that this species should be transferred to the genus Hartertia, but in default of further evidence the matter is left as it is without 275. Figs. 275-276.—275, Spiroptera penihamata. Male tail. After Drasche, 1884. 276, Spiroptera turdi. Head, a, Front ; b, lateral view. After Drasche, 1884. SPIROPTERA TURDI Molin, 1860b /Synonyms.—Ascaris fissilabium Linstow, 1873; Filaria turdi (Molin, i860) Linstow, 1877&. Hosts.—Primary: Turdus musicus, T. iliacus, T. pilaris, T. merula, Sturnus vulgaris, and Crocidura leucodon; secondary: Unknown. Location.—In walls or between tunics of gizzard. Morphology.—Spiroptera (p. 205) : According to Drasche, the mouth (fig. 276 a and b) is without lips, its aperture circular, and sur- rounded by a ring-shaped five-cornered ornamentation, with 2 large lateral papillae and 4 submedian papillae behind this ormentation. Male unknown. Female mm. long Life history.—Unknown; probably involves intermediate stages in other hosts. Cori has described what he regards as larvae of this species from the earthworm.
