No. 1 is a perfectly adult raale, and agrees in every res[iect witli the description 

 aud figure in the M/.s. The females are also absolutely identical with the specimen 

 described by me I.e. 



P. opalizan.'i is evidently confined to the faunal region of I'anl As yet only 

 five specimens are known : one c? in Count Berlepsch 's collection, one S and three 

 ? ? in the Tring Museum. It seems that tlie species is by no means rare near Para 

 since M. A. Robert, who was chiefly engaged in collecting mammals, could get three 

 specimens within a few days.

The Tring Museum possesses also two cJJ ad., collected by Prof. .Steere near 

 Marguary aud Benevides in Jnly 1879.

? ad., 15. iv. 1904. No. 2086. " Iris brun." 



The Tring Museum possesses also a pair, collected by Prof Steere, in the 

 vicinity of Para. These three specimens as well as the female in the Vienna Museum 

 (coll. Natterer) are typical T. rdi/ana, only the apical third or half of the bill being 

 black ; the females are i)ure ashy grey ou the upper surface, not at all washed with 

 brownish, aud the top and sides of the head are uniform black without any white 

 streaks. 



It seems, however, that T. hrazilieii.sia (Sws.) also occurs near Para. I have 

 examined one female in the Vienna Blnseum, which 1 cannot distinguish from females 

 e.x Kio, S. Paulo, etc. The head is all over striped with lilack and white, the back 

 strougly suffused with pale brownish aud the bill almost entirely black, except at 



the base. 



I cannot believe that two forms so nearly allied as V. (•«//«/«« and 7'. brazilicii.v.-< 

 should occur side by side, and I trust further researches on the Lower Amazon will 

 prove that mighty river to separate their ranges. 



I may add that T. intermedia Cab. & Heine • is apparently based upon females
