 a fine water, but almost always very small. 



The chorus (niyiilus chorus) is seven inches long 

 by three and a half broad. The skin is of a deep 

 blue, but the shell, when stripped of it, is of a shining 

 white inclining to blue ; the muscle itself is very 

 white and excellently tasted. It is principally found 

 on the island of Quiriquina, and the coast of Arau- 

 cania. The black muscle (mytilus ater) is nearly as

 blue, and the flesh black and never eaten. . 



Fresh water muscles are also found in abundance 

 in the rivers and the ponds. I have noticed three 

 species of them, known by the names of dolliwiy 

 pellu and uthif^ but they are all of an insipid and 

 disagreeable taste. 



The tellinae are also common in Chili, particularly 

 the may CO ^ a species of rayed tellens, or sun beam, 

 and the chalgua^ which is entirely white. 



The thaca (chama thaca) is a cockle that is nearly 

 round, about four inches in diameter ; the shell is.

 with white, yellow and purple, the inner part is of

 a genus of shell-fish so called from their form. It is 

 six or seven inches long, and variegated with sky- 

 blue and brown. Both these kinds bury themselves 

 in the sand, from whence the fishermen take them 

 in great numbers.

 of pholades (pholus Chilensis) which the inhabitants
