THE NAUTILUS. 101 



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 Area, a Solecurtiis, Cni'liim 

 sinensis and a Solen. 



At Che Foo, where the shore is more bold and rocky, a few Mon- 

 odonta labio and L'Morina 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 argyroxtom-um, Patella testudinaria, 

 two Haliotis, and (.'ypraea 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.
