I do not entirely share your views here. The book by JUNIPER & al. is much
more recent (and a +/- valuable compilation of references), but it is
poorly organized by phenomena rather than by taxa, which scatters the
information across the whole book (probably with the intention to appear
scientific-ish but I just find it annoying). The prize you have to pay for
the work is far too high.
On the other hand, LLOYD despite the fact that his book is rather old it is
a concise manual presenting virtually all data known at that time in a form
agreeable for both laypersons and scientists. This book decidedly deserves
a higher ranking (must/classic). Furthermore, a cheap paperback edition is
available.

Yes, but it is especially the species described *after* CASPER which most
urgently need a review (or in some cases rather annulment!).
