. 544 DISCOVERY REPORTS Anisakis catodontis, sp. n. (Fig. i) Among specimens of A. physeteris in the stomach of a sperm whale (No. 932) at Saldanha Bay, South Africa (August 10, 1926), there were a single mature male and several immature forms of a different species. The male is about 80 mm. in length and i -3 mm. in thickness. The cuticular striations are coarse in the oesophageal region, where the interval between them is about 0-05 mm. In the middle region of the body, however, they are much finer, the interval being about 00075 mm. Each lip has a broad base and a narrow anterior lobe, deeply indented in the middle and provided with a prominent dentigerous ridge composed of coarse and irregular teeth. The oesophagus (measured from the extremity of the lips and excluding the ventriculus) is 45 mm. ^__ long. Its greatest thickness (near the posterior 01 MM. end) is 0-39 mm. The ventriculus is straight. Fig. i. Anisakis catodontis. Dorsal lip of and measures about 17 mm. in length and male, external aspect. 0-4 mm. in greatest width (at its posterior end). The nerve-ring is situated at 0-6 mm., and the cervical papillae at 0-75 mm., from the anterior end. The tail is bluntly conical and measures 0-25 mm. in length. It has only been possible to examine it in lateral view, and only a single pair of postanal papillae was observed; This was situated near the posterior end. There are numerous preanal papillae, arranged irregularly and extending forward for a considerable distance. The spicules are tubular and without alae. The left spicule measures 2-25 mm., the right 1-45 mm. in length. Their dorso-ventral diameter is about 0-03 mm. The immature specimens measure up to about 47 mm. in length and 0-9 mm. in maximum thickness, and show the same oesophageal structure as the adult male. Anisakis sp. Several immature specimens of a species of Anisakis occurred in [the stomach of ?] a humpback (Megaptera fiodosa) at Durban, July 29, 1926. Porrocaecum falklandicum, sp. n. (Fig
