216 LIVERPOOL MARINE BIOLOGY COMMITTEE. 



Kingsleyi (Siddall), Reophax moniliforme (Siddall), and 

 Miliolina spiculifera (Siddall). Forty species of Sponges are 

 recorded, including two new forms^ Aphroceras ramosa 

 (Carter), and Sycandra aspera (Gibson). A very large 

 number of Hydromedusae have been found and examined. 

 The most important form is Garveia nutans (Wright), re- 

 ferred to above. Amongst the Actinozoa is a new variety of 

 Gylista undata (Miiller), and Sarcodictyon catenata (Forbes), 

 which has been found living and kept under observation for 

 some time. The Echinodermata and the Vermes, although 

 numerous, have as yet yielded nothing remarkable. Over a 

 hundred species of Polyzoa have now been recorded by the 

 Committee, including at least one new species, Ascopodaria 

 nodosa (Lomas), allied to Pedicellina. The Copepoda, as a 

 result of the regular tow-nettings taken round Puffin Island 

 by the keeper of the Biological Station, and sent to Mr. 

 Thompson for examination, have been very numerous, and 

 have included a large number of rare and interesting forms 

 of which some are new to British seas, and the following 

 have been described as new species : 



Cyclops puffini (Thompson), Lichomolgtis sahellse (Thomps,), 

 Cymhasoma herdmani (Thomps.), and several others still un- 

 published. Amongst the higher Crustacea Mr. A. O. Walker, 

 F.L.S., has recorded some rare northern forms of Amphipoda, 

 four species of Schizopoda, two of Cumacea, and a large num- 

 ber of Decapoda. The Pycnogonida collected contain several 

 rare forms, and one, still undescribed, which is probably 

 new to science. The Nudibranchiata have been already 

 referred to above ; the lists of other Mollusca present 

 nothing of special importance. The report upon the 

 Tunicata deals with forty-seven species of which at least two 

 {Morchellioides alderi, Herdman, and Polycarpa monensis, 

 Herdm.) are new to science, while seven have not been 

 previously recorded from British seas. Nineteen of the 

 species are simple Ascidians, twenty-seven are compound, 

 and the remaining one is the pelagic Oilwpleuraflahellum. 



Several preliminary lists of the Algse of the district have 

 been drawn up, and the whole group is now in the hands of 

 Mr. K. J. Hai'vey Gibson, Lecturer on Botany in University
