Recently published Ornithological Works. 393 
to recognize, coupled with Mr. Beddard’s notes on their 
osteology and anatomy, have considerably advanced our 
knowledge of this somewhat obscure group. Mr. Rothschild 
now recognizes only five forms of Apteryx, two of which 
he classes as subspecies. These are 
1. A. australis, of Stewart Island and the southern parts of 
South Island, to which he unites A. lawryi. 
2. A. australis mantelli, of North Island, to which A. 
bulleri Sharpe is referred. 
3. A. haasti, from the mountain-range on the west coast 
of South Island. 
4. A. oweni, from South Island. 
5. A. oweni occidentalis, from South Island and the south¬ 
western portions of North Island. 
Mr. Beddard has made the great discovery that, so far 
from having no oil-gland (as stated by Garrod, Fiirbringer, 
and Gadow), Apteryx I.as this organ particularly large and 
well developed. It is an a enormous gland ” lying “just 
above the extremity of the vertebral column.” This peculiar 
structure is well figured by Mr. Beddard, hut we regret that 
he has not given us a rather more complete description of 
the plate. Mr. Beddard also contributes important infor¬ 
mation on the osteology and anatomy of these wonderful 
birds. 
63. Salvadori and Festa on the Birds of Ecuador. 
[Viaggio del Dr. Enrico Festa nell’ Ecuador. Uccelli. Parte 1. 
Passeres oscines. Parte 2. Passeres clamatores. Del T. Salvadori ed 
E. Festa. Boll. Mus. Zool. Universita di Torino, xv. Nos. 357 and 362.] 
In these two memoirs we have a full account of the 
Passeres represented in the great collection of birds made 
by Dr. E. Festa in Ecuador, which contains altogether 2892 
specimens, referable to 610 species. Part 1 treats of the 
Oscines, of which there are 165 representatives. Of these, 
five — Turdus conradi, Thryophilus leucopogon, Certhiola 
intermedia, Spermophila cequatorialis, and Cyanolyca angelce 
—are characterized as new. Ten others are stated to be 
new to the avifauna of Ecuador. There are also such
