Upon the Anatomy op Phalangium Opilio Latr. By Alfred Tulk, M.R.C.S., &c. 
(From the “ Annals of Natural History.”) London, 1843. pp. 38. With 3 Plates. 
The attention bestowed by many of the more recent writers on 
Entomology, upon the hitherto neglected tribes of the Linnoeaii Ap- 
tera, is a circumstance of much interest, the different orders of that 
class having been at length acknowledged to afford the most valuable 
assistance in determining the natural classification of the Annulose 
Subkingdom. It is, therefore, with pleasure that I announce the 
memoir, of which the title is given at the head of this notice, in 
which Mr. Tulk has investigated the anatomy, both external and 
internal, of a very curious group of Arachnidous animals; with 
which, notwithstanding the extreme abundance of some of the 
species, our knowledge hitherto has been very superficial. The 
genus Phalangium, indeed, in their tracheal mode of respiration, 
subarticulated bodies, and exposed didactyle cheliceree, constitute 
one of the primary types of the great class Arachnida, being in 
these respects intimately allied to the two other equally anomalous 
groups, Chelifer and Solpuga; * neither of which have hitherto been 
satisfactorily investigated. Of the great care bestowed upon this 
memoir, I am able to speak from personal knowledge, although I 
am not sufficiently acquainted with the minute details of the 
internal anatomy of these tribes to offer an opinion on some of the 
results at which the author has arrived. I trust that he will not 
consider the subject as exhausted, especially as he has not given any 
account of the early states of these insects. 
* These three types constitute the order which I have termed Adelarthrosomata.—Ent.
