 same is very unique. Wz" 2.00 



2. Cardium cardissa, L. Nicobar Ids. 

 A remarkable shell, pure white, concave

3. Cardium ringens. Chem. China. 

 This shell is remarkable in that while 

 the valves fit perfectly at one end, at the 

 other they barely touch at their points, 

 which are extended about one-eighth of 

 an inch, leaving small openings. It would 

 be interesting to know the practical use 

 of same. \Vz" 1.50

 real Heart Shell of remarkable form of 

 sculpturing. It is completely covered

 in regular rows. Color a rich pink shade. 

 Common on mud flats. 3" 1.00 



5. Cardium oblongum, Chem. Greece.

 a very thin periostracum over part of the

 for food. 2Vfeto3"1.00 



6. Asaphis deflorata, L. Bermuda and 

 other parts of the world. The prevailing 

 color is white tinged at one end with 

 purple but as all of the shells of this 

 genus are very variable, there are usually 

 other color shades. There are only seven 

 known species but they include hundreds 

 of color combinations. 2" 50c

 shell and has been shipped into this 

 country in vast quantities for several 

 decades. It is usually sold in various sizes

 3 to 4 years are beautifully shaded with 

 brown. 50c to 6.00

9. Cardium unedo, L. Philippines. 

 Here we have a handsome shell that 

 seems to be a sort of intermediate be- 

 tween other species. It is deeply ridged 

 with yellowish-white, the ridges being 

 barred with red. Wz to 2 l /2" 1.00 



10. Cyclina chinensis, Chem. Japan. 

 Although this shell would be classed as 

 smooth it shows concentric ridges which 

 are adorned with a bluish shade. Interior 

 pure white. There are 12 known species 

 but I have seldom had more than one or 

 two. 11/2" 75c
