. Bulletin of the British Museum (Natural History) Zoology. B. Pseudoceros concinnus: A, dorsal surface of body in life; B, cephalic region of body; C, tentacular eye-cluster. uterine canal divides into three longitudinal branches lying dorsally to the vasa deferentia. Pseudoceros caerleopunctatus Palombi, 1928 Locality. Kabret, Suez Canal, (Palombi, 1928). Description (from Palombi). Elongate-oval forms, mm long and up to 8 mm wide. Ground colour of dorsal surface creamy yellow; margins spotted with deep blue, each spot surrounded be a bluish areola of reticulate appearance. Outer branches of areolae do not anastomose so that the yellowish ground-colour extends between the blue spots. Blackish punctuation follows margin of body irregularly. Eyes un- evenly distributed along anterior margin of body. Cerebral eyes numerous, arranged in two, symmetrically-disposed, pyriform clusters. Single male pore. Vasa deferentia proceed anteriorly, give off a pair of large swellings and continue inwardly to separately enter sides of well-developed pyriform seminal vesicle; prostate relatively small; penis-stylet present; male antrum narrow. Pseudoceros concinnus (Collingwood, 1876) Kaburaki, 1923 Proceros concinnus Collingwood, 1876 Localities. In 3-30 metres, Mayotte, Comoro Is (P. Bouchet leg.); under rocks at South Point, Inhaca I., Mozambique (V. Gabie leg.). Description (). When alive, the body of specimens from Inhaca I. in the southern region of the Mozambique Channel, was elongate and measured 15-40 mm in length. Prominent marginal tentacles deep blue. According to a water-colour painting of the living worm, the ground-colour of the dorsal surface is pale lemon, with a greyish border. This border bears blue spots at regular intervals throughout its course. Dorsally, there is a median band, lighter than the ground-colour, wider anteriorly than posteriorly. All traces of coloration and markings have been lost in preserved specimens,. Please not
