islauds whence the ty]>e of ( '. crus-^iro-striH might have come, do not differ from 

 those of Abingdon and Biadlue, whei'e the tjpe of C. Kariegntiu had been found, 

 and since we find some birds from several of the islauds inhabited by this form to 

 agree with the type of C. crassirostris. 



We have already given our reasons for uniting the genera Geospiza and 

 Camarhynchus. 



We have before as specimens of (/. crassirostrin (= vuriegatas) from Charles, 

 Chatham, Indefatigable, James, Albemarle, Jervis, Duncan, Abingdon, and Biudloe 

 Islands. From several of these we have no black-throated adnlt males. Descriptions 

 of this species are given by iSchiter & Salvin, tSharpe, and the most complete by 

 Kidgway, I.e. 18!t7. 



The types of G. tariegatns were procured on Abingdon and Biudloe. Mr. 

 Towusend did uot find it there, uor did Messrs. Baur & Adams come across it, and 

 therefore Dr. Baur donbted the locality, declaring that " it was certainly not true " 

 that G. mri('(jatjis and G. haheU were ifound simultaneously on Biudloe and 

 Abingdon ; but we shall see that it is nevertheless true that these forms occur 

 together. 



Ilidgway (I.e.') reprints the three descriptions purporting to have been taken from 

 the same sjiecimen, "the type," now in the British Museum. We have compared 

 the latter also, but we do nut think that it is the type at all ! This will account for 

 the discrepancies in the various published descriptious. The type of G.crassirosfris, 

 according to the descriptious and figure of Gould, and in the Voi/age of the Bcngle, 

 had no black crown, sides of head and ear-coverts, while the supposed type now in 

 the British Museum has these j)arts black, as described by Salvin, I.e. 



It would perhaps seem that Sharjje (I.e.) had agiiin the real type, without a 

 black head, before him when he wrote Vol. XII. of the Catalogue of Birds, but the 

 shortness of his description leaves it doubtful.

The type of G. psittacula (Gould) is said to have come from James Island. 

 We consider the birds from James, Indefatigable, Barriugton, Jervis, and Duncan 

 to belong to the same form, while we are somewhat doubtful with regard to those 

 from Charles Island. We. have also one very young bird from Chatham, of which 

 it is im]iossible to say with certainty whether it belongs to G. psitlaeula psittacula 

 or uot, but which does uot disagree with the latter.

We have only fonr skins from Charles Island, and they are sil females. Three 

 of them have black bills, a character not to be seen in our (api)arently) adult 

 females from other islauds. The bill seems a little higher, the upper jaw especially, 

 than in specimens from other islands.
