I may state that I have seen type specimens of Helix joppensis, 
Bulimus benjamiticus, and Melania judaica, the two former of which 
are unquestionably good species. Helix genezerethana is perhaps 
only a large variety of H. nummus, Ehrenb. 
8. CONTRIBUTIONS TOWARDS A MORE COMPLETE KNOWLEDGE OF 
THE AXIAL SKELETON IN THE PrRimATES. By St. GEorGE

The great interest which has been felt of late as to the value and 
extent of the anatomical resemblances and differences between Man 
and the rest of the Primates has led to many researches, which have, 
however, been mainly directed to a consideration of the head and 
extremities, and especially of the bony framework of those parts. 
To the various details given by Cuvier and others, respecting the 
cranial structure of the highest Apes as compared with each other 
and with Man, such careful and minute comparisons have from time 
to time been added by Professor Owen, in his well-known and justly 
esteemed memoirs on the subject, published in the ‘Transactions’ of 
this Society, and last of all by Professor Huxley, in his elaborate
