NARRATIVE. 45 



Nereis foliosa, Glycera sp., Sevpula quadricornis ; 



Ebalia sp. and other small crabs ; 



Shells of Dentalium octagonum, Eburna canaliculata, and other Molluscs; 



Leptoclinum sp., and Branchiostoma {Dolichorliynchus) indicus. 



Halobates was seen on the surface in quantities during the afternoon, and a tow- 

 net gathering taken in the evening, after dark (about '. p.m.), contained Corycceus 

 obtusus, Labidocera puvo and L. hroyeri, Pseudodiaptomus serricaudatus, and a new 

 species of Centropages. On the following evening, after dark, we again got very 

 much the same series of Copepoda.* 



In the little bay between Gibbet Island and Glosenburg (tig. 7) the bottom is fine 

 sand, ripple-marked, and with occasional boulders. The entrance is bounded by a 

 chain of submerged rocks covered with Alga; and Corals. The bottom and sides art' 

 not unsuitable as a locality for biological experiments when in the condition in which 

 we saw them, but the situation is exposed, and there is probably a heavy surf rolling 

 into the little bay during the south-west monsoon. We examined this bay and 

 also the creek behind Gibbet Island with some care, as the locality had occurred to 

 us as a possible position for the biological laboratory, and moreover Haeckel in his 

 book on Ceylon had strongly recommended it for the purpose (see below, pp. 4G, 47). 



On February 15th we examined the south-eastern corner of the bay inside 

 Watering Point, both by dredging and on shore. The hauls are united as 



STATION XXXVII. North-west to north-east of Watering Point, about 200 yards 

 off shore ; depth 7 fathoms ; bottom fine dark sand with some broken coral in 

 places. Nearer the shore, inside Watering Point, are small coral reefs. 



Various Alcyonaria and living Corals, chiefly Madrepores ; 



Synapta sp. (?) and Holothuria atra : 



Filograna sp. and Leucodore sp. ; 



Ccdappa sp. and some Ebalid Crabs, Hippa asiatica, and some Pagurids ; 



Margaritifera vulgaris (dead shells). 



We then landed at Watering Point to examine the shore, and were struck by the 

 filthy and insanitary condition of the water which was then being pumped into 

 water-boats to supply ships, from the old Portuguese tank. We explored the beach 

 in both directions, and also the cliffs above, and, from the boat, the shallow water 

 lying off the beach, with a view to reporting on this corner of the bay as a possible 

 site for our marine laboratory. The advantages are the shelter and protection from the 

 monsoon afforded by the headland, purity of the sea-water, and the presence of hard 

 patches at the bottom in places where there is a fringe of living coral, and where we 

 had found evidence of a few pearl oysters living naturally. The disadvantages are 

 however very serious, viz., the complete isolation and the comparative inaccessibility. 



v Me. Hornell, tow-netting at Galle since, lias obtained these same Copepoda with the addition of 

 Calanopia ellipHra, Acartia centrum, LaMdoeera clchiincata and a new species of Lichomolgiis.
