106 MB. S. O. EIDLET ON ZOOPHYTES AND SPONGES 



Alcyonidium^ gelatinosum, Linne. Two quite small spe- 

 cimens. 



Hab. Station 2, 40 fathoms. 



Distrih. North Atlantic and Arctic seas (common) and South 

 Africa (Oates). 



[Alcyonidium parasiticum, Fleming ? A convoluted mass 

 of dark colour, containing a considerable amount of sand between 

 the cells. I am doubtful whether this specimen should not be 

 referred to the Tunicata. It is attached to a shell. 



Hah. Station 1, 42 fathoms.] 



Anthozoa. 



Alcyonitjm digitattjm, Linne. Abundant at both the sta- 

 tions. Those from Trawl No. 3 include two large specimens and 

 one small orange-coloured example ; the rest, as well as those 

 from Dredge No. 2, were dirty white. Those from the latter 

 source were not large. The largest specimen has enclosed in 

 its base what appears to be a large Balanus. 



Hah. Stations 1 & 2, 40-42 fathoms. (Also obtained by ' Pom- 

 merania.') 



Distrib. North Atlantic and North-Sea coasts, common. 



Hydeozoa. 

 The German expedition obtained a considerable variety of 

 Hydroids here. The only species I have to notice is 



Hydeactinta echinata, Fleming. A small colony covers a 

 shell which is perhaps Littorina littorea. 



Hal. Station 2, 40 fathoms. 



Distrib. Firth of Forth (common, Herdman Sf Leslie*) and 

 northern seas. 



Spongida. 



No Sponges were obtained by the ' Pommerania ' in this neigh- 

 bourhood. 



Amphilectus Edwaedi, BowerbanJc. 



Isodictya Edwardii, Bowerbank, Mon. Brit. Spong. ii. p. 325 ; iii. pi. Iviii. 

 figs. 15-18. 



Isodictya gracilis 1, id. op. cit. ii. p. 333 ; iii. pi. Iviii. figs. 23-26. 



Amphilectus gracilis, Vosmaer, pars, Notes from the Royal Museum of
