number of boreal forms, some of which can be traced along the 
Aleutians to Alaska and down as far as Vancouver. 
These northern waters of the Yellow Sea on the Chinese side and 
the Gulf of Pechelli are not conducive to molluscan life on ac- 
count of the immense quantities of mud poured in by the Yangtsze 
and the Hwang Ho Rivers. The amount of this deposit is almost 
incredible. ‘The shore line from the mouth of the Yangtsze, several 
hundred miles north, is a great mud bank that is rapidly extending 
out and filling up the shallow sea. The few Pelecypods that rejoice 
in such surroundings must keep awake to avoid being “ snowed 
under.” They are exceedingly difficult to obtain, and especially 
when the icy winter winds blow as they do in that inhospitable re- 
gion. From such stations I secured an Arca, a Solecurtus, Cyclina 
sinensis and a Solen. 
At Che Foo, where the shore is more bold and rocky, a few Mon- 
odonta labiv and Littorina sitehana rewarded a diligent search at low 
tide. 
I made a desperate attempt to take advantage of the excellent 
collecting in the island of Formosa, but the circumstances of my 
visit to that most beautiful spot was such that I found it dangerous 
to venture out. Some natives, however, brought me quantities of 
beach worn shells, out of the lot of which I selected a few fairly 
good specimens of Chlorostoma argyrostomum, Patella testudinaria, 
two Haliotis, and Cyprea isabella. 
The collector in China must be of a patient and amiable disposi- 
tion to endure the throng of gaping fools that follow and ply him 
with a thousand questions. The quick tempered man is sure to get 
into trouble and get no shells.
