of the Loo-chuo Islands. 285 



collection, appears to me to be absolutely identical with it. 

 On the other haiulj Z. japonica, with its pale chestiiiit-brown 

 flanks and sides of breast, and Z. palpebrosa, with its much 

 yellower-green upper parts, appear to me to be quite 

 distinct. 



It is interesting to know that the Loo-choo species is 

 identical with that from South China, Hainan, and Formosa, 

 but differs from both its Japanese and its Philippine-Island 

 representatives. 



Passer montanus. 



Passer saturatus, Stejneger, Pr. U. S. Nat. Mus. 1886, 

 p. 19. 



Mr. Pryer has sent a number of examples of the Loo-choo 

 Tree Sparrow, which does not differ from the European bird 

 in any respect. 



Carpophaga jouyi. 



lanthcenas jouyi, Stejneger, American Naturalist, 1887, 

 p. 583. 



Mr. Pryer has sent several examples of this fine Pigeon. 

 It is nearly allied to C. ianthina, but differs from it in having 

 the plumage bronzed with green instead of reddish purple, 

 and in having a white collar across the upper mantle. 



TrERON FORMOSA. 



Treron permagria, Stejneger, Pr. U. S. Nat. Mus. 1886, 

 p. 637. 



Treron sieboldi, Seebohm, Ibis, 1887, p. 179. 



An example sent by Mr. Pryer agrees exactly with females 

 from Formosa in the Swinhoe collection. Dr. Stejneger is 

 quite right in supposing that Swinhoe described his species 

 incorrectly : primary-coverts should vend. greater wing-coverts, 

 as he suggests ; the only other feathers with pale margins 

 being the secondaries. There still remains the difference in the 

 tail. In Pryer^s bird the tail measures 4| inches, and is not 

 graduated to the extent of \ inch ; Swinboe's bird has a tail 

 4| inches, graduated to the extent of \ inch; whilst Dr. Stej- 

 neger's bird has a tail 6 inches long, graduated to the extent 

 of I inch. This looks like individual variation rather than
