Yellow liiver, tlie Gulf of Peeliilli is for tlie most parf muddy, 

 and in tlie neig-libomliood of Sliangliai tlie Tvhole seaboard 

 is poor owing to tlie enormous amount of fresh water brought 

 down by the Yang-tse-kiang. Wei-h-ai-wei, thougli possessing a 

 good rocky shore, appears to be rather barren. In a letter quoted 

 by Mrs. Gepp in the Journal of Botany (vol. xlii. p. ICl) Dr. 

 Boydeu writes as follows : " The fact which struck me most was 

 tlie absence of large seaweeds, e.g., Fucus and Laminana. 

 Possibly this may be due to the sheltered situation of that part 

 of Lm-kung-tao Island . . . but even on the seaward side 

 there seemed to be very few. This may be due to the coldness of 

 the water from the absence of a warm current, these waters being 

 outside the influence of the Kurosiwo, or Japan stream. The 

 specimens were got in pools left by the tide in the rocks, which 

 were for the most part flat. On the seaward side the rocks are 

 very precipitous, shelving down several hundred feet. The rocks 

 ai:e metamorphic, consisting of beds of quartzite, gneiss, 

 crystallite, and limestone, cut across by dykes of volcanic rock 

 and granite. Mica abounds everywhere. AVhere the seaweeds 

 were found the rocks were niostfy granite and gneiss." Dr. 

 Uoyden s 1D13 material evidently con+ains several littoral and 

 rock-pool species, but such plants as Desmare.Hia viridt.'f and the 

 species of Sargassa were doubtless washed ashore from the sub- 

 littoral region.

 though they belong to a district far south of Wei-hai-wei, to take 

 this opportunity of putting thorn on record. Some Formosan
