100.* TRITICELLA KORENII, G. 0. Sars. 



In the report from this laboratory for 1911 Professor Meek 

 recorded the finding of this species growing on two specimens of 

 Calocaris macandrese, a crustacean which is only rarely found on 

 this coast. Triticella is growing on the back, legs and telson in 

 thick clumps, but after a closer examination I have come to the 

 conclusion that while the colony on the telson and uropods is 

 undoubtedly T. Icorenii, those on the back and legs must be referred 

 to T. boechii. The zocecia in these latter are much shorter, while 

 the frenaculum is very distinct, and is at least one-third of the length 

 of the cell from the base. 



This year the stomach of a locally caught sturgeon was opened 

 and found to contain a great many of the Calocaris, which were in 

 a fairly good condition. Most of those which were in a fit state for 

 examination were found to be covered with dense colonies of 

 Triticella korenii. 



Previous British localities, Kerrera Sound, Oban ; Berehaven, 

 south-west Ireland. 



101.* TRITICELLA BCECKII, G. 0. Sars. 



On the back and legs of Calocaris macandrece from 34-35 fathoms 

 east of St. Mary's Island. Previously recorded from Christiania 

 Sound on Geryon tridens ; Berehaven, south-west of Ireland, on 

 Portunus depurator (Duerden, Proc. Roy. Irish Acad., 3rd ser., vol. 

 III., No. 1) ; the Irish Sea (47-60 fathoms north-west of Bradcla 

 Head) on Calocaris macandrece (L.M.B.C, 8th Report) ; and Ply- 

 mouth on Gonoplax rhomboides (M.B.A., new series, vol. VII., No. 2). 



102. VALKERIA UVA (Linnaeus). 



In tide pools on Corallina officinalis ; frequent. Alder. 

 Very common on various small algae in tide pools, Cullercoats. 

 * var. CUSCUTA (Linnaeus). 

 In a tide pool, St. Mary's Island. 



Small colonies dredged from Stations IV., V., VII. and VIII. 

 None of these colonies exceeded half-an-inch in length.
