The specimens of Nemerteans w7hich I now propose to describe were collected by Prof. Haddon in Torres Straits during the year 1889. Most of the species have been previously named, the only new species being three Lineidse. In none of these specimens was the whole animal preserved, so that it is impossible to say whether a caudal appendage was present or not; yet, although the chief feature relied upon in the existing system of classification for the determination of the genus was absent, the fragments in each instance comprised the whole of the anterior end, the anatomy of which is sufficient to distinguish them from any species of the family yet described. Consequently I have thought it advisable to give them specific names whilst assigoing them provisionally to the genus Cerebratulus. HETERONEMERTINI. Fam. EUPOLIID^E. EUPOLIA DELINEATA.

The chocolate-coloured lines are well preserved by tbe chromic acid in which the animal was fixed; they are perfectly continuous and number about 24 in all, those on the dorsal surface being rather more numerous and more clearly marked. In these respects it resembles a specimen described by Biirger from Java (2. p. 234), rather than those found at Naples, in which the lines are fewer and more broken.
