REPORT on a Collection of TOW-NET GATHERINGS 
made by T. C. Ryley, Esq., on the WEST COAST of 
NORWAY, up to the North Cape, during June and 
July, 1888. 
By Isaac C. THompson, F.L.8., F.R.M.S. 
[Read llth January, 1889.] 
THE collection which furnished the material from which 
this report is drawn up was made by Mr. Ryley during a 
summer cruise of the steam yacht “Argo,” belonging to 
Alfred Holt, Esq., of Liverpool. 
Mr. Ryley was furnished with one of the very fine-meshed 
tow-nets of the ‘‘Challenger”’ pattern, and all the material 
kept was at once transferred to bottles containmg a 
preservative solution composed of glycerine, water and 
alcohol, with boric acid as an antiseptic. 
Thirteen bottles of material in all were obtained, each 
bottle being numbered and corresponding to a note entered 
at the time, with particulars as to date, time of day, 
locality, general atmospheric conditions, &c. The entire 
contents of every bottle I have examined under the micro- 
scope. As might be expected, the vast proportion of the 
material consists of Copepoda, sixteen species being 
obtained. The rest consists chiefly of quantities of the 
marine Cladoceran Hvadne nordmanm, a few Amphipoda, 
Schizopoda, Cirripedia, various larval Crustacea, Annelids, 
Appendicularia, Medusz, Peridines, and fish ova. 
The various species may be classified as follows :— 
PROTOZOA. 
FLAGELLATA. 
Ceratium tripos.
