Text-boob of Invertebrate Embryology.* — Drs. E. Korschelt and 
K. Heider have published the second part of their “ Lehrbuch der ver- 
gleichenden Entwicklungsgeschichte der wirbellosen Thiere.” In nine 
chapters they describe the development of Crustacea, Palteostraca, 
Arachnoidea, Pentastomida, Pantopoda, Tardigrada, Myriopoda, and 
Insecta. In the last chapter there is a general discussion of the 
ontogeny and phylogeny of Arthropods. The Crustaceaus are regarded, 
with Dohrn, as derivable from Phyllopod-like ancestors, and these 
perhaps, as Hatschek suggests, from Annelid types. Nauplius and Zoca 
are cenogenetic larval forms. The Palaeostraca are separated from 
their neighbours, and the Arachnoidea from other Tracheata. 
Mollusca. 
Land Molluscan Fauna of British New Guinea.! — Mr. C. Hedley 
reports on land shells from British New Guinea, and enumerates 110 
species, a fair proportion of which are new. In this interesting region 
these shells fall into four rather distinct geographical divisions ; thero 
is an alpine fauna, whose sole known member is Rhytida globosa ; the 
region lying between Port Moresby and the Fly river probably gave 
origin to the tropical fauna of Queensland, the colonists migrating across 
the dry bed of the Torres Straits. A third province commences at 
South Cape Island in the west, and includes the eastern extremity of 
New Guinea, with various outlying islands. The fourth fauna includes 
the Louisiade, Dentrecasteaux, Trobriaud, and Woodlark Archipelagoes. 
In the case of some species each island ajrpears to possess a form, which 
is generally a variation peculiar to it. 
Air-breathing Mollusca of United States.f— Mr. W. G. Binney has 
published a fourth supplement to the fifth volume of the report on air- 
breathing Molluscs of the United States, in which he believes he brings 
our knowledge of this subject up to date. 
Glossary of Molluscan Terms.§ — Prof. A. C. Apgar has prepared a 
glossary of terms used in describing Molluscs which the begiunner at 
the study may find of use.

Nervous System and Zoology Affinities of Cyprsea.|| — M. E. L. 
Bouvier states that this short memoir is purely topographical, and con- 
tains no new fact of even slight importance ; those, however, who require 
the information it contains should consult it. The author takes the 
opportunity of discussing some of the statements of B. Haller.
