of which a systematic account is given, varied by disqui- 
sitions on the allied species and subspecies which have been 
examined and compared. Synallaxis rutilans amazonica and 
S. r. tertia are described as new subspecies. 
We observe that Alcedo dea of Linnzeus, which has hitherto 
been usually considered to refer to a Moluccan Kingfisher 
(Tanysiptera dea), is here used for a Jacamar, Urogalba 
paradisea, which is now called “Urogalba dea dea”! We fail 
to understand the necessity of this remarkable transfer, for 
which no sufficient reason is given. 
In Herr Hellmayr’s second chapter, on the collection from 
Obidos, 42 species are registered. None of these are new, 
but a specimen of the rare Psittacula deliciosa is the “ first 
in any European Collection.” 
65. Hellmayr on Birds from Teffe, Amazons. 
[On a Collection of Birds from Teifé, Rio Solimoes, Brazil. By C. E. 
Hellmayr. Nov. Zool. xiv. p. 40 (1907). | 
After leaving Obidos (see above) Mr. Hoffmanns went up 
the Amazons to ‘i'effé (Ega) on the south bank of the great 
river, and procured for the Tring Museum an interesting 
collection, of which Herr Hiellmayr gives us an account. 
It contains examples of 118 species, of which Pira hof- 
mannst, Dysithamnus schistaceus heterogynus, Thamnomanes 
cesius persimilis, and Rhamphocenus melanurus amazonum are 
new species and subspecies. Xenops genibarbis pelzelni trom 
S.E. Brazil is also described as a new subspecies in this paper. 
Mr. Hellmayr makes it a principle to quote only “the 
original descriptions (of his birds) and such references as 
strictly pertain to the faunal district in question.” He 
would save his brother ornithologists a great deal of trouble 
if he would add in each case a further reference to the work 
in which the name that he adopts may be found. For 
instance, where are we to look for “ Crocomorphus flavus ” 
(op. cit. p. 25) or Leucolepia modulata rufigularis (p. 41) ? 
It is also quite incorrect to add authors’ names to designa- 
tions which they never employed. For instance, we are
