120 Hong Kong, China April 1854 26th The weather still bad. Mr Kern is now absent, at Canton, where he will I fear have an unpleasant visit. 27th The weather now becomes warm and pleasant, the wind being S.W. Today I went down the harbor to Liampo Pass- age, and caught a view of the open sea. She tide runs very swiftly through this passage, the depth being 25 f., and the bottom gravelly. Here I dredged a Comatula, an Asterina?, several inter- esting Actiniae, an additional species of Notothuria, and many other new animals. Dredging was very difficult how- ever, on account of the swiftness of the tide and the nature of the bottom; so that after several difficult cases of "fetching up" we ran in to the rocks of the Hong Kong shore, where as the tide fell, I got many interesting shells; and a Chirodota of the N.E. Arctic type —very active, scarce even retracting its tentacula which it uses in progression— it's skin was also quite tough. Re- turning up the harbor, I found, just 121 Hong Kong, China April 1854 below low water mark, numerous large masses of a bright red spongia, and several long-spined Echini. 28th Taking a row-boat with four men and Pelkey, I went further down the harbor than ever before. In a bay (Coral-bay of my chart see p. 120) N.E. part, I found a considerable variety of corals (Astrea, Madrepora etc.) many of large size, attached to the boulders below low water mark. Among these boulders were two species of "fiche-le-mar" of large size; and on the corals were many small crustacea new to me. On the rocks at Liampo Passage at extreme low water I got a great variety of crustacea, ascidians, shells (as Cypraea Arabia) a new Echinus, and many other species new to me— all found under the stones, which here were very large but easily turn- ed. 29th Today I overhauled and arranged the species of Brachyurous Decapods
