An important work, written both in Dutch and French. The sexual 
organs of both sexes of Phalangium cornutum , P. parietinum, and Lio- 
banas rotundus are fully described and figured. For a review of this 
work by W. M. Yan Hasselt, see Tijdschr. Ent. xxvi. pp. 105-115. 
L. P. Gratacap, in Am. Nat. xvi. p. 1020, details experiments in which 
Phalangium dorsalum evinced considerable excitement in oxygen, and 
lived twenty-four hours.

In the introduction, the literature on this subject is reviewed. The 
subject itself is treated under five heads — i. The cuticle and muscular 
system, ii. Tho intestinal channel and oxcretory organs, iii. Circula- 
tion and respiration, iv. Generative organs, v. Nervous system and 
sense organs. In the second portion of the work, tho intestinal canal is 
divided into fore, middle, and terminal ; and tho Malpighian tubes are 
described. The sexual organs, both male and female, are fully de- 
scribed. 
B. Bossler, Z. wiss. Zool. xxxvi. pp. 671-702, pis., treats fully on the 
digestive and generative systems of Phalangiidea . The lateral marginal 
thoracic glands of Opilio albescens were found to emit an aromatic odour, 
confirming the views of J. C. C. Loman. 
E. Simon, Bull. Ent. Ital. xiv. pp. 38-47, records 16 species of Phalan- 
giidea from Southern Italy, 4 being new. The known species are Astro- 
bunus Jcochi , Thor., Liobunum dorece, Canestr., silvaticum , Sim., Phalan- 
gium opilio , Linn., propinquum , Luc., segmentatum, Sim., Egcenus crista ,
