MARINE BIOLOGICAL STATION AT PORT ERIN. 25 



time has been so fully occupied with other duties that he 

 has not yet been able to carry out the projected careful 

 examination of these week by week. Sagitta appeared in 

 great abundance on June 21st, but has occurred only 

 sparingly since. Pleurobrachia has occurred in all the 

 gatherings from early spring onwards, and the same remark 

 applies to Appendicularia. 



" The Scyphomedusse have been very sparingly repre- 

 sented this year. Several trips were taken in the ' Shellbend' 

 in quest of Aurelia aurita, but none were obtained. A 

 large number were, however, cast ashore on one day early 

 in July. About twenty large specimens of Bhizostoma 

 pulmo were cast ashore early in March, in the gastric 

 canals of each of which were a number of specimens of 

 Hyperia galba, and one living specimen was seen in the

 isosceles have not come under the Curator's notice. 



" Eleven dredging excursions have been undertaken in a 

 small boat, and hauls taken in various parts of the bay, 

 outside as well as inside the break-water. In one such 

 excursion the following species were taken : — Glytia 

 johnstoni, Obelia geniculata, Asterias rubens, Astropecten 

 irregularis, Ophiura ciliaris, 0. albida, Echinus esculent us, 

 E. miliaris, Nereis sp., Portunus pusillus, P. puber, 

 Stenorhyncus rostra tus, Eupagurus bemhardus, E. 

 prideauxii with Adamsia palliata, Grangon vulgaris, 

 Virbius varians, Galvina farrani, Facelina drummondi, 

 Aplysia punctata, Bissoa parva, var. interrupta, Phasia- 

 nella pullus, Sepiola sp., egg capsules of Loligo forbesi, 

 with developing embryos. 



"The frequent occurrence of rough weather has prevented 

 the Curator from gaining more than a general idea of the 

 nature of the bottom of the bay beyond the lowest tide 

 mark. The shoreward border of the great sea- weed bed,
