966 General Notes. [November, 
regarding both as true Carnivora; the former on account of the 
supposed scapholunar bone reported by Gervais, the latter on ac- 
count of the single flesh-tooth. He restricts the Creodonta to those 
forms which have two flesh-teeth, if any. From the Leptictidæ 
he excludes the genera Leptictis, Mesodectes, and Ictops, placing 
them in the Insectivora. He therefore changes the name Leptic- 
tidæ to Proviverridæ. Schlosser does not agree to the intro- 
duction to the Creodonta by Cope of the tritubercular families 
usually referred to the Insectivora, viz., the Talpidæ, Chryso- 
chloridide, Centetide, Mythomyidz. and Tupæidæ; but he does 
not give his reasons for this view. 
The following remarks may be made on the above positions of 
Dr. Schlosser. The supposition that Hyzenodon possesses a 
scapholunar bone has been shown by Professor Scott to be an error, 
so that this form must be retained in the Creodonta, to which it is 
connected by Pterodon. Specimens of Miacidz in the Princeton 
Museum show that this family also possessed no scapholunar 
bone. This, together with the non-trochlear astragalus which I 
have described, shows that the Miacide must also be referred to 
the Creodonta. These points admitted, it becomes much easier to 
believe that the Carnivora are the descendents of Creodonta, 
through the Miacidæ. (The supposed connection between Oxye- 
nidz and Felidz I denied in my last phylogeny in the article on 
Creodonta in the AMERICAN NATURALIST for 1884.) The exclu- 
sion of the three genera above named from the Leptictide, (Pro- 
viverridz) has little significance, until the reasons for separating 
e Creodonta from the tritubercular Insectivora can be shown. 
r. Schlosser’s representation of my phylogenetic views is very 
inaccurate, owing to a misunderstanding of the dates of publica- 
tion of my respective papers. The oldest of these is the Vol. 1m. 
Report U. S. Geol. Survey Terrs., sent to press in 1879, and 
not issued until February, 1885. The next in point of date are the 
illustrated papers on extinct Vertebrata, issued at various times in 
the AMERICAN NATURALIST. My latest phylogenetic opinions, 
delivered from fuller material and more mature reflection, were 
published in a paper on the “ Evolution of the Vertebrata, P ay 
gressive and Retrogressive,” in the February, March and Apr! f 
numbers of the American NATURALIST for 1885. In the last O 
hese papers the Lemuroidea are separated from the Bunotheria 
and placed in the Taxeopoda n 
they are allied. This does not include the Mesodonta (P elyco- 
dus), which being unguiculate, remains with the Bunotheria. In 
. paper all are derived from carnivorous Marsupialia, 
in accordance with the view of Hackel’s “ Schopfungsg* 
schichte”
