78 : THE ZOOLOGIST. 
the same size but distinct from the one here figured has been 
described by OC. J. With, of Copenhagen (Ann. Mag. Nat. Hist. xv. 
p. 123 (1905)), as C. equester, of which eight females and thirteen 
males were found beneath the elytron of a beetle (not identified) at 
Tavieta, Kilimanjaro. Some of the smaller species of the Pseudo- 
scorpionide have been seen clinging to the legs of flies, a habit 
generally considered as denoting a convenient means of transport 
from place to place rather than an intention of preying on the flies 
themselves; but these specimens from Natal are much larger, and 
must prove a considerable inconvenience and annoyance to their 
hosts. The specimen here figured measures 54 millim. in length of 
body, and is apparently an undescribed species, but being in a dried 
condition is not suitable for specific diagnosis.—W. L. Distant. 


NOTICES OF NEW _ BOOKS. 
The Vertebrate Fauna of North Wales. By H. HK. Forrzst. 
Witherby & Co. 
Tu1s book is a real contribution to natural history, and per- 
tains to a British area whose fauna required the historian. A 
number of papers on Welsh ornithology have recently appeared 
in our pages, and they are not unused in this volume; we hope 
that ‘The Zoologist’ will be equally in demand for records when 
a volume on South Wales appears. The work commences with 
short obituaries of the deceased zoologists of North Wales, and 
portraits of many of them give a peculiar value to the pages, 
while a good bibliography of the writings of living naturalists is 
also compiled. 
Of the mammals, we read that at the present time 41 species 
are known to occur in North Wales, 8 became locally extinct 
within the historic period, while 15 have been identified only 
from remains found in limestone caverns of the prehistoric era. 
No list of mammals for North Wales had previously been pub- 
lished save that by Kyton in 1836. 
Two hundred and seventy-two species of birds are enumerated ;
