Meinert publishes (Naturli. Tidsskr. 3rd series, v. pp. 1-32) 
a monographic revision of the Danish species of this order, which 
he prefaces with a sliort general account of their structure, with 
especial reference to the parts of the mouth. He distinguishes 
a labrum, Avhicli is usually coalescent with the forehead, and 
three pairs of buccal organs. Of these the second and third 
pairs (maxillae and labium) are amalgamated, and situated on the 
same plane. The most characteristic parts of the maxillae are 
the pedicles {stipites maxillares) and maxillary plates {lamince 
maxillares), the latter being transverse plates situated be- 
tween the hinge-joints, and regarded by the author as repre- 
senting the sternal part of this pair of appendages. The lamina 
labialis is a triangular plate representing the sternal part of this 
pair ; and behind this, when it is present, or behind the maxillary 
laminae, there is a vaulted transverse plate, the hypoatoma. The 
antennae are said by the author to consist generally of eight 
joints, the last joint being always very small and concealed. 
The author divides the order into two primary sections, cha- 
racterized as follows : — 
Section I. Body crustaceous ; labrum connate, emarginate, with three horny 
teeth j mandibular stalks entirely exposed ; maxilhir pedicles appendiculate, 
exposed ; anteimse indistinctly 8-jointed ; legs not more than 7-jointed j anus 
in last segment, with an anal lamina. Families Julidce, PoUjdesmidce, and 
Glomeridce. 
Section II. Body horny ; labrum separate, emarginate, not toothed j man- 
dibular, labial, and maxilhir pedicles partly concealed, the latter not appen- 
diculate } antennm distinctly 8-jointed j leg-s 8-jointed, except first and 
second pairs ; anus in penultimate segment, anal plate 0. Polyxenus. 
The genera referred to are : — Julus with II species (6 new), Planndus with 2 
species (I new), with 1 species, Polydesmus with 1 .species, Craspedo- 
soma with 2 species, Glomeris with I species, and Polyxenus with I species. 
The new species are ; — Julus luscus, Meinert, 1. c. p. 9, beech -woods of North 
Zeeland; J.foetidus, Meinert, l.c. p. 11, Denmark generally; J. sjcelandicus, 
Meinert, /. c. p. 13, near Soro; J. silvarum, Meinert, / c. p. 13 (= J. luridus, 
Porath nec Koch), Denmaih generally ; J. fallax, Meinert, 1. c. p. 15 (=J 
ferrugineus, Porath nec Koch), near Copenhagen ; and J. ruyifrons, Meinert, 
1. c. p. 17, Sorb and Copenhagen. 
Planiulus venustus, Meinert, 1. c. p. 20 (=/. pulcliellus, Koch nec licach), 
Denmark generally.
