MAMMALIA. 



(Ann. Sci. Nat., Ser. 3, Vol. XV., p. 63, 1851). The same form 

 has been recorded from the Pliocene near Siena, Italy, by Prof. 

 Capellini (Atti K Ac. Lincei, Ser. 4, Vol. I., p. 18, 1885") ; and 

 specimens of rostra in the British Museum from the Suffolk Red 

 Crag Nodule-bed have been identified by Mr. Lydekker (Quart. 

 Journ. Geol. Soc., Vol. XLIIL, p. 14, 1887, and Cat. Foss. Mamm., 

 Part v, p. 64, 1887) as well as a periotic bone, from the same hori- 

 zon, in the Museum of Practical Geology, which is provisionally 

 referred to this species. 



A caudal vertebra from the Coralline Crag in the British 

 Museum (No. 33,459) may perhaps belong here (Cat. Foss. Mamm. 

 Part v, p. 66, 1887). 



The specimen figured below, in illustration of this species, 

 was dredged off the Essex coast, but evidently came from the 

 Nodule-bed of the Red Crag; it is the left half of a rostrum 

 which has been split vertically in the middle line. The outer view 

 (fig. A) shows the characteristic form and enlargement of the 

 anterior premaxillary region. The maxillary and submaxillary 

 canals are shown, as well as the union of several canals in one 

 cavity at the hinder part of the maxillary bone. 



CHONEZIPHIUS PLANIROSTRIS. 



Rostrum in the possession of the Rev. A. D. Philps, of Coggeshall. One fifth 

 natural size. A. Outer view of left side, showing anterior end of the mesethmoid 

 cavity. B. Restored riew of upper surface. C. Inner view, showing longitudinal 

 section of rostrum, exposing the cavity left by the unossified mesethmoid.
