 24 (R. Friedlander & Sohn, Berlin), 1896.— The Deutsche 

 Zoologische Gesselschaft announce their purpose to prepare a 

 comprehensive representation of the whole animal kingdom, 

 naming and giving the characters of every known species now 

 living, or which has in recent times become extinct. About fifty 

 specialists have been selected to prepare the " lieferungs " on the 

 special groups. It is expected that 25 years will be required to 

 finish the work. The publishers (Friedlanders of Berlin) have 

 sent out a sample number on the Heliozoa, which is before us. 

 In these 24 pages 59 species are cited, full references to original 

 descriptions and bibliography for species, genera and orders are 

 given, generic descriptions, and brief indications of the distinctive 

 specific characters, and habitat and geographical distribution are 

 given in each case. The systematic part and the publishers' part 

 are also all that could be desired. The first lieferung is an- 

 nounced for the beginning of the year 1897. h. s. w. 



8. The Comparative Morphology of the Galeodidaz, by H. M. 

 Bernard. Trans. Linn. Soc, London, 2d ser., vol. vi, part 4, 

 pp. 305-417, plates 27-34, 1896. Few comparative anatomists 

 or morphologists are so suggestive in their teleological discussions 

 as the author of the present paper on Galeodes. His first 

 important work on the Apodidce, published in 1892, in which the 

 Crustacea are deduced from a bent carnivorous annelid, has only 

 lately received the recognition it deserves, and, remarkably 

 enough, several inferences made upon theoretical grounds have 

 been fully verified by recent discoveries relating to the ventral 

 anatomy of Trilobites. The adverse criticism which this book 

 first received was entirely uncalled for, and is an instance where 

 dogmatism and autocracy are allowed to take the place of 

 judiciousness. Hostility was incited mainly by its attitude on 

 the " Limulus-an-Arachnid " question, although the work itself 

 was not in the slightest degree polemical. 



The Galeodidw are undoubted Arachnids possessing marked 

 primitive characters. They show the original metamerism of the 

 body more strongly than any other Arachnid. The only fused 

 segments are the three anterior cephalothoracic somites. The 

 others are free, including also the ten segments of the abdomen. 

 Therefore, these animals offer inviting opportunities for compara- 

 tive morphological studies. 



Most important and interesting are the discussions on the 

 phylogeny of the Arachnida and their lack of affinity with the 

 Merostomata. An ancestral Arachnid is reconstructed having
