[Karsch, F.] Neue Juliden des Berlinen-Museums, als Prodromus einer 
Juliden MoDographie. Z. ges. Naturw. (3) vi. pp. 1-79. 
This article is prefaced by general and critical remarks on the difficulty 
of the subject, the characters, variations, geographical distribution, &c., 
of the lulidce, the writings of previous authors, and a table of genera, 
the following being admitted : Stemmiiulus, Gerv., Pceromopus^ Karsch, 
AlloporuB, Porath, Glyphipilus, Gerv., lulus, Linn., Spirostreptus, Brandt 
(divided into 2 sections, Odontopyge and Nodopyge, Brandt), Spiroholus, 
Brandt. 
Ryder, J. A. List of the North American species of Myriapods belong- 
ing to the family of the Lysiopetalidoe, with a description of a blind 
form from Luray Cave, Virginia. P. U. S. Nat. Mus. iii. 
pp. 524-529, woodcuts. 
8 species and a new genus. The group is considered to lack definition, 
as at present constituted. Abnormal respiration in Trichopetalum 
lunatum, as described, suggests more important differential characters 
than hitherto supposed. Some observations on cavernicolous animals 
with and without eyes, tend to support the origin from forms with eyes. 
Polydesmus (Paradesmus) pecuensis, Karsch, noticed from Peking, &c., 
Karsch, B. E. Z. xxv. p. 219 ; P. olfersi, Brandt, is a Cryptodesmus, id. 
MT. Miinch. ent. Ver. iv. p. 143. 
Spirostreptus ceplialotes, Voges, ? = macrotis, Gerst., $ ; id. Z. ges. 
Naturw. (3) vi. p. 3. 
Spiroholus. Karsch gives the name scobina to a peculiar structure, 
which always occurs in pairs on the first segments, and which he finds 
useful as a sectional character, 1. c. p. 3 & 4. S. arboreus, Sauss., varia- 
tion noticed ; 2 varieties are named respectively krugi and gundlachi, 
id. 1. c. p. 9. S. crassicollis, Peters, is closely allied to, if not identical 
viiih, pulvillatus, Newp. ; Mattozo, J. Sci. Lisb. viii. p. 195.

Rhinocricas, Karsch, Z. ges. Naturw. (3) vi. p. 11. Section of Spirobo- 
lus ; base of several, or of most segments with scobina. 
Pceromopus, id. 1. c. p. 12. Allied to lulus ; eyes consisting of three 
transverse rows of ocelli ; first pair of legs truncated ; type, P. lysiopeta- 
linus, sp. n., 1. c., California.. 
Zygonopus, g. n., Ryder, 1. c. p. 527. Lysiopetalid, hairy: 6th pair of
