' New fpccics. Although Mr. Lawrence mentioned both Tres Xl.irins nnd .''oeorro speeimcns in his originnl 

 deperii>tion of I'nruta iiistttaris, his description and me.asureracnts were taken from a specimen from the former 

 locality, which may, therefore, be considered the typo. With the same material before mo as that which Sir. 

 Lawrence examined, I am able to appreciate rea<lily the differoDces of plumage which he |<bints out as dis- 

 tinguishing the birds from Socorro. In fact, I am somewhat surprised that ho considered them the samo 

 species. The Socorro bird is, upon the whole, more different from C. {ninilarit than the latter is from C. niyri- 

 iora.
