286 EIGHTH PACIFIC SCIENCE CONGRESS 



Sole?! gaiidichaudi Chemn, 1843, and E7isis macha Molina, 1782, 

 are called NAVAJUELAS DE MAR (Razor-shells). The first is found 

 in a small area, from Valparaiso to Coquimbo, and the second, from 

 Valparaiso to Magallanes up to the Atlantic coast, reaching the Gulf 

 of San Matias (Carcelles, 1950). Both are sand species found at great 

 depths and collected at low tide. 



Pholas (Thovana) chilensis Molina, 1782, commonly called COMES 

 (Piddock) is found from the Gulf of Panama to the Chiloe Is. Con- 

 sidered one of the best shellfish and known by its two anterior plates 

 with anterior-central nuclei, a small and transversial middle plate and 

 a long and narrow posterior plate. No lines in the third posterior of 

 the shell. 



Mulmia bicolor Gray, 1837; M. edulis King, 1831, and M. byronen- 

 sis Gray, 1838, species which because of their resemblance to the TACAS 

 (Hard clams) are called TAQUILLAS (Small hard clams). Their areas 

 of distribution are extensive: M. edulis is found from Callao to the 

 Strait of Magellan, M. byronensis from Salaverry (Peru) to the Strait 

 of Magellan, M. bicolor from Copiapo to Valparaiso. (Some authors 

 consider M. bicolor Gray synonymous with M. edulis). They are 

 frequently found in the markets of a number of sea ports in Chile.
