summary of our present ,<:nowledge of the fossil forms, although most of 

 the material must be taken from foreign sources. The American contingent, 

 however, beiny so small, will not be contrasted with the European as here- 

 tofore, except so far as it may appear desirable. 



About fifty-eight fossil species of this family have been described or 

 indicated in a less degree than usual described or figured. They repre- 

 sent twenty-one genera, of which only one. an American, is regarded as 

 extinct. Fourteen of these species, of five genera, come from the Pleisto- 

 cene, the remainder, but including three of the Pleistocene genera, from the 

 earlier Tertiaries. Two of the Pleistocene forms, one on each continent, 

 are regarded as existing species.
