Dr. Eduard Brandt has published his researches on the 
dentition of the Shrews in the pamphlet mentioned above (p. 3). 
We give a detailed abstract of it : — 
The author commences his treatise with an historical sketch of 
the difterent views entertained by various authors with regard 
to the nature of the small teeth intercalated between the large 
’ front teeth and the true molars. He shows that these vviews 
were arrived at in the most arbitrary manner, and that only W. 
Peters (Monatsber. Ak. Wiss. Berlin, 1852, p. 174) really 
observed ah intermaxillary suture between the second and third 
of these small teeth in Crocidura sacralis (Ptrs.) , whence he 
concluded that this subgenus is provided with two anterior and 
four lateral incisors above, two incisors below, and two canines 
above, lower canines being absent; the molars would be 
He attempted also the determination of the dentition of 
Fachyura and Dlplomesodorij without, however, having observed 
the sutura maxillo -interm axillaris in these subgenera. More- 
over his observation regarding Crocidura was not in accordance 
with that of Geoffroy St. Hilaire, who says that the intermaxil- 
lary suture is behind the last small lateral tooth in Crocidura 
aranea (Mem. Mus. dHIist. Nat. i. p. 307, tab. 15. fig. 8). 
This latter view was confirmed by Max Gemminger and Joh. 
Eahrer, who state in their work, ‘ Fauna Boica,^ 1851, i. 
p. 60, We have not only convinced ourselves of the correct- 
ness of Geoffroy St. Plilaire^s and Duvernoy's opinion (viz. that 
all those small lateral teeth belong to the intermaxillary in Croc, 
aranea) j but we were enabled to trace- with certainty the ' 
extent of the intermaxillary in fullgrown specimens of Sorex 
vulgaris and G. fodiens. In Sorex fodiens the fifth lateral tooth, 
and in G. vulgaris the fifth and sixth do not belong to the 
intermaxillary ; and therefore these teeth only are really pre- 
molars. 
Tlie genus Sorex of Cuvier has been divided into the sub-
