NOTICES OF SOME TURKESTAN BIRDS, SevertsOV. 421 



wings (all the measures in English feet and inches) ; lower co- 

 verts of the wing snowy white (adults) — but here my English 

 forsakes me. 



Adultus. — Cinerascens, albo-fulvescens, striis scapalibus fere 

 albis ; remigibus tectricibus majoribus aire et rectricibus nigro- 

 fuscis, dorso postico toto albido, tectricibus inferioribus alas niveis.* 



Medio veste. — Colore saturatior, cano-fulvescens ; maculis 

 scapalibus albicantibus ; dorso postico et uropvgio albofulves- 

 centibus, tectricibus inferioribus alae albis, margine dilute 

 canofulvescentibus, remigibus et rectricibus nigricantibus. 



Junior. — Intense fuscus, striis scapalibus, praesertim infra, 

 dilute fulvescentibus ; praeter remiges, rectricibus et tectricibus 

 majoribus uuicoloribus nigricantibus ; fere ut Aquila imperialis 

 variegatus. 



The middle plumage most resembles Gypsfuhus, but the } r oung 

 and adult are very different ; and the linear collar feathers never 

 change their form by age. Lives in the Alpine regions, near 

 the eternal snow. It is I find your Gyps Himalayensis which 

 name has precedence. 



2 — 4. Aquila minuia, pennata, and guttata, Brehm., differ 

 by their variation from age, thus : — 



2 — 4. Aquila minuta, pennata, and guttata, 



2. — Aquila minuta. — Omni astate fusca, supra et subtus : mar- 

 gine carpali et metacarpal! alas unicolore fusco : Junior ab 

 adulta aagre distinguenda, sed adultas striaa scapales nigrce subtus, 

 aliquot intensiores. 



3. — Aquila pennata, Gin : — subtus fusca, ut Aq. minuta, sed 

 margine carpali et bracalisf aliquot albo-variegatis. 



Medio veste. — Abdomine etiam albo-variegato, vel subtus in- 

 tense fulvo ; bracalisf semper albo-variegatis, distinctior quam 

 primo veste. 



Adulta. — Pecfore dilute fulvo, abdomine albo, scapis infra 

 ubique fuscis. Bracalis trausversim colore fusco-flavescente 

 fasciatis. 



4. — Aquila guttata, Jun. — Subtus albo-fulvescens, fasciis 

 scapalibus fuscis, crebris, tenuissimis. 



Medio veste. — Subtus, ut junior, ochraceo-alba, sed fasciis 

 scapalibus, ut senior!, maculis etiam guttaaformibus bracalarum. 



Adulta. — Subtus a gula tota nivea, pectore won-fulvescente : 

 striis scapalibus pectoris longioribus et latioribus quam j union', 

 abdomine tenuissimis; bracalis fusco guttatis, non trausverso 

 fasciatis, ut A. pennatce. 



* These Latin diagnoses are all written in such an abbreviated form, that I have had 

 to supply ease endings, &e. If there is any error it is I, and not Herr Severtsov, who 

 is to be blamed. — Ed. 



f I don't know this word — I should have thought it should be braecis, but Herr 

 Severtsov, writes it thus several times distinctly and in one case explains it as hosen, 

 which, I suppose, means tarsal plumes. — Ed.
