Pohjno'e^ which genus he showed in his former work to be, as a rule, 
anangian, M. Olaparede refers to a work on the histology of Ilermione hystrix 
as nearly ready for publication. His death (the greatest loss zoology has 
suffered for many years) will not, it is believed, prevent its publication. 
2. Professor Ghube took an opportunity last year of spending some 
weeks ih examining the fine collection of Annelids in the Museum of Natural 
History at Paris, now arranged in agreement with the work of Professor 
Do Quatrcfages (llistoire des Annel^es). He revises many of that author’s 
genera and species, pointing out some which are synonyms, and describing 
others in greater detail. The following is a list of the Annelids referred to 
by Professor Grube : —
