INSECTIVORA. 
Dobson, G. E. A Monograph of the Insectivora , systematic and ana- 
tomical. Part ii., including the families Potamogalidce, Chrysochlo- 
ridce , and Talpidce. London : 1883, 4to. 
A continuation of the important work on the Insectivora noted last 
year [Zool. Rec. xix. Mamm. p. 25]. The present part, like the last, 
contains a full systematic arrangement, with a detailed account of the 
osteology and anatomy of the various forms included in it, and also an 
appendix to the last part, in the shape of notes on the genera Microgale 
and Geogale , which should be included in the Centetidce. Fifteen excellent 
plates illustrate the osteology and anatomy of the species referred to.

Phil. Soc. Wash. v. p. 118. 
The author considers that if Solenodon is raised to family rank, as has 
been done by Dobson, so also should several other forms hitherto 
reckoned only as subfamilies. He therefore proposes the following new 
families : — Rhynchocyonidce , Myogalidce , Oryzorictidce , and Geogalidce. 
He also proposes the names Dilambdodonta for the W-toothed Insectivores, 
and Zalambdodonta for the Y-toothed.
