d ad. pileo sordide cinereo-carto vix cervino tincto, versus nucham cervino-cinereo : collo postico et dorso 

 antico cervino-cinereis : corpore supra reliquo sicut in Tetraogallo caucasico picturato, sed pallide 

 cervino-cinereo nee saturate cinereo : alis sicut in T. caucasico, sed tectricibus majoribus magis caeruleis 

 et ad basin minus vermiculatis : Cauda sicut in T. caucasico, sed paUidiore : fronte, stria superciliari, 

 capitis lateribus et gula. cervino-albis : regione suboculari pallide cana, et stria magna, in colli lateribus 

 utrinque saturate cana : gutture et pectore superiore cinereo-canis, plumis cinereo-cervino terminatis 

 et nigro guttatis : pectore rebquo cinereo-cervino, griseo-nigro vermiculato, plumis omnibus ad basin 

 cseruleo-canis : abdomine centrali scbistaceo-fubginoso : crisso sordide cervino, subcaudalibus cervino- 

 albis : bypocbondriis ceeruleo-canis, utrinque castaneo striatis et nigro marginatis, plumis nonnullis in 

 parte suprema vermiculatis, et plumis in parte ima cinereo-cervinis nigro-cinereo vermiculatis et cervino- 

 castaneo marginatis : rostro flavido, ad basin pallidiore, naribus rufo-aurantiacis : plaga nuda circum et 

 infra oculos laete flava, : pedibus laete rufo-aurantiacis, unguibus saturate corneis : iride fusca. 



2 minor et sordidior : pileo vix cervino et saturate griseo notato : stria in colli lateribus et gutture antico nigro 

 notatis, hoc griseo vermiculato : plaga nuda, oculari minore : rostro et pedibus sicut in mare, sed paulo 

 sordidioribus. 



Adult Male (Koroskeui, Taurus, 15th April, 1876). Crown dull ashy blue, with a buff tinge gradually 

 merging into ashy buff, this latter colour pervading the hind neck and fore part of the back ; rest of 

 the upper parts as in Tetraogallus caucasicus ; but instead of the general tinge of colour being clear 

 dark grey, it is lighter buffy grey ; wings as in Tetraogallus caucasicus, but the larger wing- coverts are 

 rather bluer and less vermiculated on the basal portion ; tail as in Tetraogallus caucasicus, but rather 

 paler ; forehead, a streak over the eye, sides of head and neck creamy white, the portion below the eye
