NARRATIVE. 21 



Copepoda many, including a conspicuous blue form Centropages violaceus, and 

 also Oithona siinihs, Euterpe gracilis, Ectinosoma atlanticum, Temora discaudata 

 and T. stylifera, Eucalanus subtenuis, Calanus vulgaris, Calanopia elliptien, 

 CoryccBits speciosus and C. venustus. 



[Note. In coming across the Indian Ocean to Ceylon we used silk tow-nets day and night to strain 

 the organisms from the sea-water running from the tap in one of the bath rooms. In two of these 

 gatherings I obtained the pelagic Amphioxus (Branchiostoma pelagicum, Giinther). One specimen was 

 taken in a coarse net on January 16th, to the south-east of Sokotra, about halfway between Perim and 

 the Maldives ; and five others were found in a finer net on January 20th, after passing Minikoi Atoll, 

 and therefore between the Maldives (where this species was found by Stanley Gardiner) and Ceylon. 



Amongst other interesting or novel forms found on the way to Ceylon were : a new species of 

 Centropages (rather widely distributed), Miracia minor (taken near Sokotra, previously known from 

 Gulf of Guinea), Mecynocera claim (common), Scolecithrix chelifer (Red Sea, the only known locality), 

 Pseudodiaptomus salinus (Suez Canal and Red Sea, males found for the first time), Anymone spherica (in 

 Suez Canal), Acartia dubia (Suez Canal, only known previously from Gulf of Guinea), Pseudocyclops 

 oblusalus and Canuella perplexa (both European forms, now found in Suez Canal). These will be discussed 

 fully by Mr. Isaac Thompson and Mr. Andrew Scott in their Report on the Copepoda see below, p. 227.] 



On Saturday, February 1st, we dredged and trawled at various localities between 

 Negombo and Chilaw, covering an extent of about 23 miles. The distance was 

 generally from 4 to 5 miles off land, and the depth varied from 8 to 14 fathoms. 



This day's hauls can be grouped into two localities; the first (Station II.) from 

 opposite Ooluwitti to oft" Mararilla, half-way from Negombo to Chilaw, and the second 

 (Station III.) off Chilaw ; we dredged and trawled at both, as follows : 



STATION II. From 7 to 14 miles north of Negombo, 5 miles offshore ; 8 to 9 fathoms ; 

 bottom coarse yellow sand, shells, stones, and small coral ; temperature of sea, 

 77"5 F., specific gravity, T023. Two hauls of fish -trawl and several of dredge. 



Pachychalina sp., Acanthella carteri, Hircinia sp., and Siphonochalina sp. (pale 

 lilac, with large oscula occupied by small colourless Alpheus) ; 



Masses of living corals (up to 20 X 14 X 6 inches), many solitary corals, mainly 

 Stephanoseris rousseaui and Heteropsammia michelini, small scarlet Actinians ; 



Linens sp., Aspidosiphon corallicola (in the solitary corals), Lumbrinereids, 

 Hesione sp., Axiothea tubes (in masses), Serpula actinoceros, S. quadricomis, 

 Sabellaria bicornis, and many Polyzoa ; 



Antedon variipinna and another species (many), Luidea rnacidata, Clypeaster 

 humilis, Laganum depression and Echinodiscus auritus, Salmacis dussumieri, scarlet 

 Ophiuroids, and Phyllophorus cebuensis ; 



Leucothoe spinicarpa and other small Amphipods and Isopods not yet determined, 

 some Macrura, Galathea sp. (black and white), and Pilnmnus vespertilio ; 



Young pearl oysters (in quantity), Avicula vexillum, Conns marmoreus and a few 

 other common shells, Philine sp., Aplysia sp. ;
