fll) Larvae of Lobsters- -We have not previously 

 met with these in the tow-netting^s, and their occurrence 

 among'st the plankton is worthy of special notice. One 

 was taken oft' Ynys Each on -Tuly 1-lth, one off Llanon on 

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

 one in the last pelagic stage in Lune Deep on August 2r)th. 



(12) The Erich theus stage of Squill a was recorded 

 for Cardigan Bay in the report published last year. It 

 was found again in the same area iu 1905. In July and 

 August these larvae appeared to be fairly uniform in their 

 distribution between Ynys Each and St. Tudwall Islands, 

 and extended seaward as far as the Patches Buoy off 

 Aberystwyth. Over 100 specimens were found in a tow- 

 netting oft' Llanon on August 9tli. 



(13) The Trachelifer stage of Jn.vea has also been 

 previously recorded. It occurred in 1905 in (Cardigan 

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

 Deep in August. Mackerel caught oft Walney early in 

 July were found to be feeding entirely on larval 

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

 One or two had been feeding exclusively on young Ja.vea, 

 and their stomachs were well filled. 



(14) Pontella lobiancoi, Canu. — Plates I. and II. 



A regular invasion of this rare Copepod into Cardigan 

 Bay was noted in July and August. It has not been taken 

 at any time on the British coasts until 1904, so far as we 

 know. Two males and one female were found in a tow- 

 netting taken oft Llanon on October 27tli of that year. In 

 1905 we have noted its occurrence on the following 

 occasions: — J^ily 3rd oft St. Tudwall Islands, 14th oft 

 Ynys Each, 17th Tremadoc Bay, 21st Tremadoc Bay, 22nd 

 oif Llanon, 31st both at New (^uay Head and Tremadoc 

 Bay. August 9th off Llanon (105 specimens), loth Xew 

 Quay Head. This is one of the Pontellas that has a leps
