forwards until reaching the base of the ventral fin, and then almost 

 to the end of the tail. 



Fin rays had begun to develop in the pectoral, dorsal and 

 ventral fins. 



Other two masses of the eggs of the gunnel were found under 

 stones in the same locality, and only one fish was seen in each case. 

 The moving of the stones disturbed the water, and made observa- 

 tions difficult. 



Protula tubular ia, Mont. A mass of tubes having a base of 

 8 inches by 5 inches and being about 5 inches in height, was brought 

 ashore by one of the local fishing boats on 16th September, 1914, 

 from 17 fathoms N.E. of Cullercoats. The creatures are now 

 Hving in a large glass jar, and have made additions to the length 

 of the tubes. Shortly after capture retraction into the tubes 

 took place if the jar was approached in anything but a very cautious 

 manner. Now the creatures are not so sensitive, and generally 

 remain fully expanded until a slight tap is given to the jar, when 

 retraction of the majority instantly takes place. 



Nerilla antennata, O. Schmidt. Found 15th January, 1915, 

 amongst Nemerteans brought in from the north side of Cullercoats 

 Bay, obtained near high water mark, and from below stones resting 

 on fine gravel and coarse sand. Unfortunately the specimen 

 when being examined alive was destroyed by the slipping of the 

 cover slip, but what notes were made from a dorsal examination 

 are here given : — 



Head. — Rounded with fringe of cilia. Tentacles three, arti- 

 culated, median with eight articulations, two lateral evidently 

 damaged and showed only three and five articulations. Palpi 

 clavate and lateral with fringe of cilia distally and anteriorly. 

 Eyes four, pale reddish purple, anterior pair wider apart than 

 posterior, which were slightly behind palpi. The anterior border 

 of the head changed somewhat and appeared less rounded as the 

 creature progressed. 



Body of nine bristle bearing segments, the first with a pair of 

 articulated cirri of six and seven articulations respectively and
