1) A. group of closely-allied species or forms, to which have been given the names of z»sw/aria, £rifonaria, ua, fosoma and fictifimbria, 
is still in considerable confusion, and we have had neither the time nor the material to work it out thoroughly. The synonymy and distribution 
here given must consequently be regarded as merely provisional.
