TEXT BOOK OF THE 
EMBRYOLOGY OF INVERTEBRATES 
By Dr. E. Korschelt and Dr. K. Heider 
Translated from the German by Edward L. Mark, W. McM. Woodworth and Matilda Ber 
nard. Revised and edited with additional notes by Martin F. Woodward. 
The broadest, most comprehensive and exhaustive work on the subject. In method of treat- 
ment the authors proceed from the special to the general. The translators, on account of the 
rapid advance of the science since the date of first publication, have supplemented the text by 
numerous additions, both in the body of the text and in foot-notes, giving a succinct statement 
of the results of recent embryological research. In this work they were fortunate in having the 
co-operation of the authors themselves, and all interpolations in the text are bracketed, thus 
rendering it unnecessary to compare with the original to ascertain what is new. Each of these 
additions, together with the foot-notes, is followed by the initial of the author, or by the word 
“Translators’ ’, to indicate the persons responsible for the new matter. 
This work is comprised in four volumes as follows: 
Vol. I. — Porifera, Cnidaria, Ctenophora, Vermes, Enteropneusta, Echinodermata. 
Vol. II. — Phoronidea, Bryozoa, Ectoprocta, Brachiopoda, Entoprocta, Crustacea, Palaeostraca. 
Vol. III. — Arachnida, Pentastomidae, Pantopoda,Tardigrada,Onychophora, Myriopoda, Insecta. 
Vol. IV. — Amphineura, Lamellibranchia, Solenoconcha, Gastropoda, Cephalopoda, Tunicata, 
Cephalochorda. 
The volumes are profusely illustrated. 8vo. cloth, uncut and unopened. N. Y. (The Mac- 
millan Co). 1895-1900. Publishers’ price, $14.25 net.
