A CONCHOLOGICAL MUSEUM. 



Conchologists the world over are interested in the work of Mr. Y. 

 Hirase, of Kyoto, Japan. I doubt if many of them are aware how 

 deeply they are indebted to him. His quarter century of explora- 

 tion of Japan, by land and by sea, of Corea, and of China, at great 

 personal sacrifice of money and time, has given to science many new 

 species, enriching cabinets all the world round with choice specimens 

 most delicately handled. 



He has an extensive and valuable collection of material, contain- 

 ing co-types of the numerous new species brought to light by his 

 efforts. He has plans for the establishment of a Conchological 

 Museum for the preservation and exhibition of this collection. He 

 has in hand cash for about three-fourths of the cost of this under- 

 taking. He still needs $5,000 to finish the work as planned.
