5. On some Nemerteaus from Torres Straits. 

 By R. C. Punnett, B.A. 1 



[Received June 29, 1900.] 



(Plates LIV. &LV.) 



The specimens of Nemerteans which I now propose to describe 

 were collected by Prof. Haddoa 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 assiguing them provisionally to 

 the genus Cerebratulus.

Fragments of a single specimen about 2-5 mm. in breadth. The 

 chocolate-coloured lines are well preserved by the 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. The absence of head-slits, the relative positions of
