This memoir must be consulted by every one interested in 
the subject. The author first gives a short history of what is 
known as to this family of the Nematoid worms, then a tabular 
list of genera, which we give further on, and, lastly, full dia- 
gnoses of the genera and the species. This monograph being 
published in the Transactions of an English Society, we should 
prefer to have had the specific descriptions all in one language, 
not, as at present, partly English, German, French, and Latin.

It would trespass too much on the space of the Record to 
give even a brief epitome of this important paper. In the latter 
part the author discusses at great length the systematic position 
of the Nematoids; between them and the Echinoderms he finds 
several strong points of resemblance. The nervous system of 
the former differs notably from that of the Annelida or Scole-
