60 CACATUA GOFFINI. 



which C. Gojfini can be based, is its much inferior size. 



The comparative measurements are as follows: 



C. sanguinea wing 290 mm. (Finsch); tail 150 mm. 

 » » » 265 » (Gould); » 150 » 



C. Gojjini » 210—220 mm.; » 115 » 



The hitherto unknown habitat of this species would thus 



be the Islands of Timor-Laut.

After a careful comparison of the two specimens with our 

 fine series from the Ké Islands , I feel sure that the birds 

 from Timor-Laut may not be considered as specifically dis- 

 tinct from those from the Ké Islands. Dr. Meyer, in his 

 above mentioned paper, has based the difference upon their 

 inferior size and the green color of the outer web of the 

 first primary. In both our two specimens the length of 

 wing is 170 mm., thus inferior to that of our smallest spe- 

 cimens from Ké. It must be remembered , however , that 

 according to Dr. Meyer , the length of the wing in the birds 

 from Timor-Laut vary from 170 to 185 mm., while our small- 

 est specimens from Ké measure but 182 mm., reason enough 

 to consider the birds from both groups of Islands to be 

 identical, the more as I cannot find the slightest difference 

 in the color of the outer web of the first primary. 



The late Prof. Schlegel , in his Catalogue of the Leyden 

 Museum, preferred uniting the whole group of Geoffroyus 

 in which the color of the hind neck does not differ from 

 that of the mantle, under the name of Edectus personatus.
