ticulars above given. We shall take an early opportunity of 

 exhibiting them at a Meeting of the Zoological Society; for cer- 

 tainly no such large series of the bones of any species of Dodo 

 has ever before been collected. We need not, however, say 

 more here on the subject, except to remark that an inspection of 

 the specimens would seem to induce the opinion that after all 

 the Didus riazarenus of Mr. Bartlett and the Pezophaps solitarius 

 of Strickland are only the opposite sexes of one and the same bird 

 — a very singular fact when the great difference in the size of the 

 specimens is taken into consideration. We are glad to say that, 

 at the instance of Mr. P. L. Sclater, the British Association has 

 voted a liberal sum of money to continue the researches thus 

 commenced with so much promise. 



At the same Meeting of the British Association the Com- 

 mittee on Zoological Nomenclature, which was appointed in 

 1862, presented a Report which recommended the adoption of 

 a Code of Bules, differing in only one respect of any great im- 

 portance from that formerly compiled by the late Mr. H. E. 

 Strickland. This Keport having been first discussed at some 

 length in the Committee of the Section, was read in the Section, 

 and the Code of Rules as recommended, being formally put to 

 the Meeting, was unanimously adopted, and copies of it ordered 

 to be printed for circulation among zoologists both at home 

 and abroad. We shall probably have more to say on this subject 

 hereafter.
