Collection methods: In the introduction, Burton says that he is reporting fauna "the horizons of which are known to the author", and states that he has collected 480 specimens. It is also clear that he is pulling from other sources, some published (in difficult to obtain British journals), some not. It's difficult to tell which are his and which aren't. This is not a definitive source for this collection, but I think it's a reasonable place to start.
