liours' illness. Dr Conant, left in charge, unselfishly refused to hasten 

 his own departure and leave his friends behind ; both he and Dr Clark 

 were taken ill, and Dr Conant died on his way home. This number 

 of the Circular is especially devoted to memorial sketches of Prof. 

 Humphrey and Dr Conant, whose untimely deaths have caused an 

 irreparable loss, not only to the biological department of the Univer- 

 sity, but to all who ever came in contact with these earnest and 

 single-minded workers. The Circular also contains short papers by 

 Conant, Clark, and others, on the viviparous Synapta of the West 

 Indies, the folhcle-cells in Salpa, the Cubomedusae, and other subjects. 



Mr W. E. Hoyle has sent us a supplement to his " Catalogue of 

 Eecent Cephalopoda," including the 79 new species published between 

 1887-1896. Most of the novelties are from eastern seas, and are due 

 to Drs Ortmann and Brock, and Mr E. S. Goodrich ; but the most 

 important systematic work of recent years is Dr Jatta's Monograph 

 on the Cephalopoda of the Gulf of Naples, which was reviewed by 

 Mr Hoyle in our own pages. Mr Hoyle, who of course writes as an 

 autliority, states that he has found scarcely any omissions from the 

 lists given in the Zoological Record. This supplement, as was the 

 original catalogue, is published by the Eoyal Pliysical Society of 

 Edinburgh ; the date 1897 is printed on the wrapper, and we learn 

 that it is a reprint from the Proceedings (pp. 363-375); but we do not 

 gather from the pamphlet before us wliat was the volume in which it 

 originally appeared, or whether it is to be purchased in its separate 

 form, and if so at what price. We mention these points merely be- 

 cause we were given to understand a short while since that the Eoyal 

 Physical Society of Edinburgh was initiating some useful reforms in 

 connection with authors' reprints.
