﻿256 Proceedings of the Royal Physical Society. 



When two or more papers by the same author have 

 appeared in one year, they are distinguished by letters of the 

 alphabet. 



As regards nomenclature, the regulations and recommenda- 

 tions of the Commission of the International Zoological Con- 

 gress have been adopted, and some pains have been taken to 

 ascertain the dates of publication as accurately as possible. 

 There are, however, difficulties in this task, depending 

 especially on the uncertainty of the dates of publication of 

 Ferussac and d'Orbigny's monumental work. When these 

 can be definitely ascertained, changes in the accepted dates 

 of publication of some species will probably result, along 

 with one or two changes of name ; but, so far as I can see, 

 these are not likely to be either numerous or important. 

 In this connection, I have to acknowledge the invaluable 

 help of my friend, Mr C. Davies Sherborn, whose 

 enthusiastic and self-denying labours in the compilation of 

 the Index Animaliuni are known to and appreciated by all 

 systematists. I must also place on record my indebtedness 

 to the card catalogue of zoological literature, issuing from 

 the Concilium Bibliographicum at Zurich, under the direction 

 of Dr Field.

1 I think it highly probable that this species should be referred to the 

 genus Stauroteuthis, and quite possible that it is synonymous •with 

 S. hippocrepium, but Joubin gives no particulars regarding the form and 

 position of the internal cartilage.
