532 REPORT — 1893. 



Herdmani (on Turritella shells), Panthalis Oerstedi, Eumenis Jeffreysiiy 

 Bougainvillea muscus. 



4. Thirteen miles N.W. of Port Erin, 60 fathoms, mud, bottom tem- 

 perature 48° F., surface temperature 60° F. : Found Calocaris Mac- 

 andreoe, &c. 



5. Five miles off Dalby, 30 fathoms, ' reamy ' bottom (sand and mud 

 mixed) : Sole, turbot, and brill all spawning here. Lima Loscombii, Gere- 

 hratulus (? angulatus), Ghcetopterus sp., Thyone fusus and T. raphanus, 

 Eurynome aspera. 



6. Four miles off Fleshwick, 23 fathoms : Fecten opercularis and P. 

 maximus in quantity ; Molgula sp., Corella parallelo gramma, Ascidia 

 pleheia, Ascidiella venosa, Polycarpa comata, Suherites domuncula. 



7. A mile and a half off Bradda Head, 12-15 fathoms : Styelojisis 

 grossularia, Bowerhankia caudata, Eurynome aspera, Terebella nehulosa, 

 Thyone raphanus. 



On all these expeditions, in addition to the animals picked out and 

 preserved at the time, surface and deeper gatherings with the tow-net 

 were taken by Mr. I. C. Thompson ; and samples of the bottom and of the 

 ' dredge debris ' were kept, and these were afterwards carefully examined 

 by Mr. I. C. Thompson for copepoda, by Mr. A. O. Walker for amphi- 

 poda and isopoda, by Mr. A. Leicester for small moUusca, and by Dr. 

 Chaster for foraminifera. The sponges collected have been identified 

 by Dr. R. Hanitsch, and several other workers at the Port Erin Bio- 

 logical Station have assisted the Committee with particular sets of 

 animals. The additions to our knowledge of the fauna during the year 

 will now be given, taking the groups in zoological order. 



Dr. Gr. W. Chaster reports that amongst the Foeaminipeea he has 

 examined two are new to science, and one is a form which seems to 

 require a new genus. 



Amongst the Sponges examined by Dr. R. 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 (Desmacidon) fruticosa, dredged off Calf of Man, 

 40 to 50 fathoms ; HaUchondria {Amphilectus ?) expansa, off Garwick 

 Head (previously known from Skye); Suberites sp. (?), some very large 

 masses, dredged halfway between Isle of Man and Lancashire, 20 

 fathoms; Raspailia s^). (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 Perwick Bay (recorded by Bowerbank 

 from Tenby and Sark only). 



We have found in the pools at Port Erin amongst other Htdroida 

 the Lafoea pygmoea of Alder, and have been able to prove that it is 

 really a Galycella ; and Sertularella Oayi has been added as a new 

 record to the district. In all fifty-seven species of zoophytes have been 

 recorded. 



Mr. J. H. Vanstone, curator at the Port Erin Biological Station, has 

 drawn up the following list of the Nemertida collected and identified 

 during the past year, partly by himself and partly by Mr. W. I. Beau- 

 mont, Emmanuel College, Cambridge, who was working for some time 

 at the station : — 



PrOTONEMERTINI : Carinella annulata. 



Mesonemertini : Gephalothrix hioculata. 



Metanemertini : Amphiporus lactifloreus, A. pulcher, Tetrastemma dor-
