simple tubercles, which I believe is a perfectly natural one, was made 
by W. Kowalevsky ; but the names were suggested to him by Prof. 
Owen, to whom this department of zoology owes so much. The 
modifications of the Buonodont forms, being beside the purpose of 
the present communication, have not been followed out. 
Finally, it may be asked what place must be assigned to the Musk- 
Deer in our necessarily imperfect and artificial method of expressing 
the relationship of living beings? Should the genus Moschus be 
described as constituting a distinct family, Moschide? As I appre- 
hend the value of the term “ family,”’ I think it should not. The 
characters which absolutely separate it from all the recognized Cer- 
vide, if Hydropotes is included among them, are very trifling; and 
to include Hydropotes with Moschus in one family, and leave all the 
other Cervide in another, appears to be a violation of natural affinities. 
It therefore appears most expedient to include them both as distinct 
generic modifications of the great family Cervide, recognizing of 
course that though a convenient it is not an absolutely perfect 
method of expressing their position in nature. 
Note to the tabular view of the Classification of Artiodactyla. 
The form of the odontoid process in the Zylopoda might lead to the idea 
that they were segregated from the Ruminant stock after the Tragulina had 
been given off; buf as it is also found in the horse, it is probably adaptive, as 
are the hypsodont molars. The union of the inner, and loss of the outer, bones 
of the metapodium is also a character not significant of very close relationship 
to the Pecora, as the tendency to this modification begins in the earliest period 
of the history of the group with which we are acquainted, as in Anoplotherium, 
and crops out even in some of the bunodonts, as the Peccaries. 
2. On some new Species of Erigone.—Part I.

(Plates XX VII.-XXIX.) 
The Spiders described in the following pages are, with one excep- 
tion (Erigone consimilis, p. 192), a portion of a fine collection re- 
ceived at various times during the past three or four years from my 
kind friend, Monsieur Eugéne Simon of Paris. The greater part are 
European, and were found by M. Simon himself in France, Corsica, 
Sicily, and Spain ; several, however, are from Morocco and Algiers. 
The twenty-four new species now selected for description from M. 
Simon’s collection all (except one) belong to the group comprised 
in Mr. Blackwall’s genus Walekenaéra ; in addition to these, nine 
others new to science (belonging to the genus Neriene of the same 
author) remain yet to be described, while the collection also contained 
examples of forty-four known species. ; a 
Rich as the genus Erigone is at present in species, it is probable
