Meetings of Section I. 37 



actually enticed workers to search for new forms (" es verleitet 

 ja vollkommen zum Suchen nach neuen Subspecies"). 



Dr. Hartert was of opinion that this was exactly what 

 was wanted. Our knowledge was not yet complete, and 

 students wished to be led in search of new discoveries, 

 because it was a laudable object to discover new facts and 

 to enlarge research and knowledge. On the other hand 

 Dr. Hartert fully agreed with the speaker that new forms 

 should not be created and named without good and 

 apparently sufficient reasons, and, if possible, only after 

 examination of a good series. 



The Hon. Walter Bothschild said that some orni- 

 thologists, in designating the typical form of a species, 

 instead of repeating the specific name as in Corvus corax corax, 

 preferred to write Corvus corax tyjpicus, but he was not in 

 favour of this method. Dr. Blasius had expressed the 

 opinion that the differences between two forms should always 

 be definitely expressed in words, but it was often impossible 

 to do so, as one could not ascertain the limits of variation 

 unless very large series were available for comparison. 



Dr. Eeichenow remarked that one was only justified in 

 altering zoological nomenclature at an International Zoo- 

 logical Congress, and he thought that any suggestions of 

 the kind should be deferred till the end of the meeting. 



Dr. Stejneger stated that, at the present time, the Zoolo- 

 gical Commission were engaged in preparing a new set of 

 rules, which would probably be put forward before the next 

 Ornithological Congress in 1910, and under these circum- 

 stances he greatly hoped that no resolution would be 

 passed on the subject of nomenclature on the present occasion. 



The Chairman then called on Dr. Blasius to reply. He 

 said that though he did not wish any resolution to be passed, 

 he thought it desirable that the present Congress should at 

 least discuss such questions of nomenclature, so that the 

 record of their opinion on such matters might act as a guide 

 at the next meeting of the Zoological Congress.

Owing to its comparative scarcity in the British Islands, 

 ornithologists in that country had few opjwrtunities of
