188G.] PROCEEDINGS OF UNITED STATES NATIONAL MUSEUM. 283 



Mr. Alexander Agassiz* records Uchinarachnius excentrieus from 

 Sitka aud Uualacb, Alaska, aud Kamtcbatka, oq the authority of Esch- 

 scholtz. The very large collection of Echini in the National Museum 

 from Alaska and Eastern Siberia does not contain any representatives 

 of this species, and Eschscholtz's observations were probably based 

 upon some other form. There is no positive evidence that U. excentrieus 

 exterds north of Puget Sound and the Straits of Fuca, although K 

 paruia is very common throughout Alaska, and in some places attains 

 a ver}' large size.
