Type. Adult male, collected at Lesse, Semljiliki Valley,

 Gyldenstolpe. Type in the Eoyal Nat. Hist. Mus. at 

 Stockholm. 



Bemarks. In all I collected a series of six specimens o£ this 

 new race, and all these specimens are very similar to the 

 type. From T. calurvs nditssumensis Reichenow, which also 

 inhabits the same region, the new form differs by its shorter 

 and weaker bill, and by the diffei*ently coloured upper tail- 

 coverts and rectrices. 



Dr. Ernst Hartert exhibited a new subspecies of Prinia 

 gracilis, which he described as follows : — 



Prinia gracilis stevensi, subsp. nov. 



Very much darker, more olivaceous than P. gracilis lepida 

 of the Indus-valley, Baluchistan, and easternmost Persia. 

 Much more resembling P. gracilis delta' from the Nile-delta, 

 but more olivaceous, not in the least rufescent, and darker 

 than P. g. pahestince. Wing, $ 44, ? 43 mm. 



Hah. Gauges and Brahmaputra regions.

 named. Mr. Stevens had several more specimens, but he

 their dark coloration, which I had already mentioned in 

 1909. 



Dr. Ernst Hartert also made the following remarks on 

 the subspecies of Argya rubiginosa : — 



The various forms of Argya (or, better, Crateropus) rubi- 

 ginosa have repeatedly been discussed, but require some 

 further rectification and explanations. 



The species was first described as Crateropus rubiginosus by 

 Iliippell, Syst. Uebers. p. 47, pi. xix. (1845), from Shoa, and 

 again as C. rufescens by Heuglin, from Gondokoro. In the
