MARINE BIOLOGICAL STATION AT PORT ERIN. 181 



is a Flacopsilina and the other an ahied form which seems 

 to require a new genus. They are from the central area at 

 depths of 20-25 fathoms. 



Amongst the Sponges examined by Dr. K. Hanitsch 

 the following are specially worthy of note : Ute glabra, 

 obtained near Port St. Mary (this is practically new to 

 British seas, as it had only been found before at Guernsey) ; 

 Esperiopsis (Desniacidon) fruticosa, dredged off Calf of 

 Man, 40 to 50 fathoms ; Halichondria {Amphilectus ?) 

 expansa, off Garwick Head (previously known from Skye) ; 

 S'liberites sp. (?), some very large masses, dredged halfway 

 between the Isle of Man and Lancashire, 20 fathoms ; 

 Baspailia sp. (new to the district), dredged off the Calf, 15 

 fathoms ; Stelletta collingsi, from the Caves at Spanish 

 Head, Port Erin ; Beniera rosea, at Fleshwick and Per- 

 wick Bay (recorded by Bowerbank from Tenby and Sark 

 only). In addition, Mr. Chopin, who was dredging at 

 Port St. Mary in August, obtained Dercitus hucklandi, 

 which is new to the Isle of Man. 



We have found in the pools at Port Erin amongst other 

 Hydroida the Lafoea pygmcea of" Alder, and Miss 

 Thornely has been able to prove that it is really a Caly- 

 cella ; while Sertularella gayi has been added as a new 

 record to the district. In all eighty-nine species of Zoo- 

 phytes have been recorded now in the L.M.B.C. district.

The small pale red anemone attached to Turritella 

 shells (see fig. 2) which we dredge from the mud off Port 

 Erin at depths of 50 to 70 fathoms has been identified by 

 Prof. A. C. Haddon as Sagartia herdmani, a species
