umbrellar cavity), Dysmorpliosa minima, Cytceandra areo- 

 lata (?), Lizzia blondina, Laodice calcarata (new to 

 European seas), and Eutima ijisignis* Mr. Browne 

 writes, in regard to his work at the Biological Station, 

 " Port Erin is a good place for Medusse. The tide sweeps 

 clean into the bay and I have found very little difference 

 between the pelagic fauna inside the breakwater and that 

 a mile or two off shore. At Plymouth one has to go 

 about two miles outside the Sound before meeting the 

 Channel tide." 



Miss L. E. Thornely reports the addition of Perigonimus 

 repens and Tubiclava cornucopia to the list of Hydroids. 



Veemes. 



Mr. Beaumont in his recently published report makes 

 the following additions to the list of Nemeetida : — 

 Amphiporus pulcher, A. dissimulans, Tetrastemma flavi- 

 dum, Prosorhochmus claparedii, Micrura purpurea, M. 

 fasciolata, M. Candida, and Cerebratulus fuscus. 



During this summer we have dredged from a gravelly 

 bottom, at 10 to 15 fathoms, in two localities near Port 

 Erin, a species of Polygordius, either P. apogon, M'Intosh, 

 or a new species. It seems to differ from M'Intosh's 

 species in having no eyes. It differs also from all the 

 three species described by Fraipont which have no eyes. 



Amongst Polyceleta Mr. Sumner records Arenicola 

 ecaudata and Ampliitrite johnstoni ; Mr. Arnold Watson 

 Autolytus alexandri (with egg-sac), and many larval 

 Pectinaria, in membranous tubes ^ inch long. 



Amongst Polyzoa Miss Thornely reports the rare 

 Triticella boeckii, found attached to the prawn Calocaris 

 macandrece, from the deep mud off Port Erin ; also 



* For Mr. Browne's observations on these and other species see his report 

 in "Fauna of Liverpool Bay," Vol. IV., 1895.
