MiVART, 1867-1871. 



In a similar spirit, the order was subsequently studied by Prof. St. 

 George Mivart.t Prof. Mivart went into still greater detail, and allowed 

 himself to be guided to a greater degree than Peters by the weight and 

 coincidence of characters. The result was that his distribution into 

 families was more perfect than that of any of his predecessors, the 

 families much more fully deiined, and the relations of all the constitu- 

 ents rendered far more readily appreciable even by the characters 

 exposed. Originally promulgated in 1867, the author reviewed the sub- 

 ject in 1871, and found cause to make very few modifications, at 

 the last period a new genus only having been based on a previously 

 known species, and some additional characters having been introduced 

 into the diagnoses of the families. The classification in question is ex- 

 hibited in the following conspectus : 



Family I. Galeopithecidoe. 



Galeopithecus. 

 Family II. Macroscelidid?e. 



Macroscelides, Petrodromus, Rhynchocyon. 

 Family III. Tupaiidfe. 



Tupaia, Ptilocercus, Hylomys. 

 Family IV. Erinaceidfe. 



Gymnura, Erinceceus. 

 Family V. Centetidfe. 



Centetes, [Hemicentetes, 1871,] Ericulus, Echinops, Solenodon. 



* A. Intestinal tract with a large casciim. 



a. Bones of lower leg separate ; zygomatic arch complete. 



a. Ulna imperfect. 



I. Galeopitheci. — Galeopithecus. 



(3. Ulna perfect. 



II. Tupayse. — Cladobates, Ptilocercus, Hylogale. 



b. Bones of lower leg coalesced ; zygomatic arch complete. 



III. Macroscelides. — Rhynchocyon, Macroscelis. 

 B. Intestinal tract simple, without cjecum. 



a. Bones of lower leg separate ; no zygomatic arch ; bulla3 ossese none ; os tym- 

 panicura ring-shaped. 



IV. Centetma. — Solenodon, Centetes, ? Ericulus, ? Echinogale. 



h. Bones of lower leg coalesced ; zygomatic arch complete ; bullre ossese more or 

 less developed ; cranium completely ossified. 

 a. Ears well developed. 



V. Erinacei, — Erinaceus, Gymnura. 



(3. Ears rudimentary or absent. 



VI. Talpina. — Myogale, Urotrichus, Condylura, Scalops, Talpa, Chrysochloris. 



c. Bones of lower leg coalesced ; no zygomatic arch ; parts of the base of the skull 



membranaceous ; os tympanicum ring-shaped. 



VII. Soriees. — Sorex.
