Calocaris macandrere, Bell. On May 31st of this year, Mr. 

 Dunn, of Whitley Bay, had in his shop a small sturgeon, about 

 5 feet long, which had been caught b}^ a local trawler 14 miles E. 

 by N. of the Tjme. On examination of the contents of this fish's 

 stomach, 120 specimens of Calocaris were obtained, as well as six 

 Polychaets, Glycera sp., and one Telhna. 



Trij2^etesa lampas (A. Hancock). In March of this year Miss 

 Koper drew my attention to the presence of a burrowing crustacean 

 in the shells of Neptunea antiqua, which she was examining for 

 Polyzoa. This proved to be T. lamjjas, and Avas found to be very 

 common. The shells were obtained from local fishing cobles which 

 had been fishing in 16 fathoms S.E. of St. Mary's Island. 



Pectinaria auricoma (Miiller). This polychaet was found in 

 numbers in the supply tank for the aquarium in March. The tank 

 had been cleaned some nine months before. At the bottom of the 

 tank were some four inches of mud and fine sand, and in this were the 

 tubes of Pectinaria, with the apex of the tubes just below the level 

 of the surface of the sediment. As well as Pectinaria there were 

 numerous specimens of Harrnothoe imbricata, together with Phyl- 

 lodoce maculata and its egg-cases, Amphitrite johnstoni, one 

 specimen of Halosydna gelatinosa, and the nudibranchs, Coryphella 

 rufibranchialis and Doris tuberculata. 



PERIDINIALES NEW TO THE DISTRICT. 



Dinophysis acuta, Ehrenberg, has been found in surface catches 

 from 6 and 17 miles S.E. and S.E. by S. of the Crumstone in August, 

 September and October. It only occurred sparingly. Size, '792 

 X -055 mm. 



Amphidinium rotundaium, Lohmann, was found in the floor 

 pool of the aquarium on the morning of the 20th of May, and 

 disappeared in the afternoon. The floor pool overflows into the 

 drain for the Laboratory. It occurred in such numbers that the 

 surface of the water was streaked with yellowish-brown hues of 

 colour. On the evening of the same day smaU numbers were found 

 colouring the sand in Cullercoats Bay. During the two following 

 days it also occurred in large numbers, and then it disappeared. 

 Length, -OlOd-'OlS mm.
