Mussel of the Month
The July 2007 Mussel of the Month is Chamberlainia hainesiana. Chamberlaindia is a genus of two species known from Thailand and Laos in Indochina.
AMNH 31070. Siam. ex. William A. Haines Collection. (type)
The genus is of some economic importance because of its utility to the pearl industry. However, from a taxonomic/systematic standpoint, we don't really have too much to say about Chamberlainia. From Brandt (1974), we know that C. hainesiana has unhooked glochidia, and thus it can only be placed in the poorly-known hodge-podge of species and genera that seem to form a grade at the base of the Unionidae branch.
