they contain nothing of particular interest. — Finally we arrive to 
a treatise of O. F. Cook: An Enumeration of the Pauropoda (Brand- 
tia VI, 1896, p. 29—32). The views of the author on the sy- 
stematic are not fortunate; he considers the Pauropoda to be a 
class and divides it into three orders, for which he constructs new 
names. If the group Pauropoda is not maintained as an order, 
we must follow Kenyon and consider it as a suborder of the Diplo- 
pods; to establish it as a class is, in my opinion, a fault, the con- 
sequences of which disturb the natural and widely adopted grouping 
of the Arthropods. His opinions on this series (on p. 30) are not 
worth mentioning. He enumerates fifteen species of Pauropoda , and 
live of them are marked with „sp. n.“. One of these new species 
is the form described by Latzel as Pur. spinosus Ryder which he 
names E. latzeli; it is in reality rather different from the American 
E. spinosus, but the characters pointed out by the author are of 
little or no value. Another of his new species, Paur. jiliformis, 
has been established on Latzel’s description of P. Huxleyi var. ftli- 
formis , but it must be dropped (see below). His three other new 
species are so imperfectly described that one could suppose that the 
diagnoses were written down a hundred years instead of five years 
ago. Furthermore he erects three new genera; one of these is 
Stylopauropus which has been proposed without characterization, but 
it is accepted in this paper. The two other new genera belong to 
the Eurypauropodidæ, but they must, at least provisionally, be re- 
jected; of this family a rich mate rial of species must be examined 
before it is possible to establish well-founded genera. 
I conclude this chapter with a summing up. Of the family 
Pauropodidæ six real species have been established, but only two 
of them have been described so that they can be recognized with 
certainty. Of Brachypauropodidæ only one species has been estab¬ 
lished. Of Eurypauropodidæ eight species have been named, but 
one of them {Trachypaur opus glomeroides Tomos va ry) has been 
withdrawn.
