(11) Larvae of Lobsters. -We have not previously 

 met with these in the tow-nettings, and their occurrence 

 amongst the plankton is worthy of special notice. One 

 was taken oif Ynys Fach on July 14th, one off Llanon on 

 the 22nd, twelve in Carnarvon Bay on August 10th, and 

 one in the last pelagic stage in Lime Deep on August 25th. 



(12) The Erichtheus stage of Squilla was recorded 

 for Cardigan Bay in the report published lasl year. It 

 was found again in the same area in 1903. In July and 

 August these larvae appeared to be fairly uniform in their 

 distribution between Ynys Fach and St. Tudwall Islands, 

 and extended seaward as far as the Pal dies Buoy oft 

 Aberystwyth. Over 100 specimens were found in a low- 

 netting off Llanon on August 9th. 



(13) The Trachelifer stage of Jaxea has also been 

 previously recorded. It occurred in 1905 in Cardigan 

 Bay during the months of July and August, and in Lune 

 Deep in August. Mackerel caught oft" Walnev early in 

 Tuly were found to be feeding entirely on larval 

 crustaceans, such as Zoea and Megalopa of Grabs, &c. 

 One or two had been feeding exclusively on young J a. tea, 

 and their stomachs were well filled.
