Treklit Species Names for Unnamed Canon Species

Below is a vast list of unnamed species from various Star Trek episodes and films, and the names which they have been given in various Star Trek books, comics, and reference works. This project was started on the TrekBBS Literature Forum, and was really expanded by user Extrocomp.  I post it here on his behalf.  I hope to find time sometime to insert the pictures instead of only links.  Email me any additions you know of to make this list more complete.
