With the exception of the list of typographical corrections below and
minor corrections not noted here, the text presented here is the same
as in the original printed version. Tables 1 and 2 were rotated so that
the width would be less than the limit of 75 characters wide. In the
tables, the title and some column headers were printed in small caps.
Those are usually displayed as ALL CAPS; but for ease of reading, they
were left as mixed case. The list of UKMNH publications was compiled
at the end of the article's text.
