TRAVERSIA LYALLI ROTHSCH.

(PLATE 5, FIG. 3.)

_Traversia lyalli_ Rothschild, Bull. B.O.C. IV p. X (December 29th,

1894); Nov. Zool. 1895, p. 81.

In 1894 I described this remarkable little bird as follows: "_Traversia_,

gen. nov. _Xenicidarum_. Differs in several important points both from

_Xenicus_ and _Acanthidositta_. Bill much larger and stouter, very little

shorter, if at all, than the tarsus; the latter about as long as middle toe

without claw, or the hind toe and claw, while in _Xenicus_ and

_Acanthidositta_ it is about twice as long as the hind toe. The principal

difference, however, is the weakness of the wing, which suggests

flightlessness, as does also the very soft and loose character of the

entire plumage, and the very Ralline aspect of the bird. There are only ten

tail-feathers, and the scutellation of the tarsus is like that of

_Xenicus_. These two points determine its position in the _Xenicidae_ at

once (cf. Sclater, Cat. B. XIV, p. 450).

"The type is: _Traversia lyalli_, sp. nov.

"Male. Above dark brownish olive-yellow, each feather with a brownish-black

border. A narrow distinct yellow superciliary line. Wings and tail

umber-brown, the inner webs darker; wing-coverts like back. Chin, throat,

and breast chrome-yellow, each feather slightly edged with greyish brown.

Flanks, abdomen, and vent pale brown, centre of feathers paler.

"Female. Upper surface umber-brown, each feather bordered with very dark

brown; wings and tail similar. Under surface buffy grey, the feathers edged

with pale brown. Total length about 4 inches, culmen 0.6, wing 1.8 to 1.9,

tail 0.8, but much concealed, tarens 0.75, middle toe 0.65, hind toe

without claw 0.5. {24}

"Habitat: Stephens Island, New Zealand. Discovered by Mr. Dr. Lyall,

lighthouse-keeper, and sent to me by Mr. Henry H. Travers."

I received nine specimens of this new bird, and was not aware that any

others had been taken at that time. As I was unable to attend the December

meeting, 1894, of the British Ornithologists Club, I asked Dr. Hartert to

exhibit the birds in my name. When he had done so and had read the

description, the Chairman, Dr. P. L. Sclater, said that the bird had also

been received for illustration and description in the Ibis, from Sir Walter

Buller, and he asked Dr. Hartert if I would not withdraw my description.

Dr. Hartert said that this was unfortunate, but he had no authority to

withdraw my description, and he and Dr. Sharpe thought that the proceedings

of the meeting should be printed without consideration of any manuscripts

which might refer to the same bird. No doubt this was hard luck on Sir

Walter Buller, but it would have been equally hard luck for me if he had

forestalled me with the new bird. He had only one specimen, I had nine, of

both sexes, and I had paid a high price for them, as types of a new bird.

My type is in Tring, and, as everybody knows, available for study by any

competent ornithologist, while Buller's type was not in any museum, and it

was uncertain to whom he would sell it afterwards. I suppose it is now in

the Carnegie Museum, Pittsburgh, to which Buller's third collection, 625

specimens, was sold for a thousand pounds, as Buller himself tells us in

his Supplement II, p. 167, under the heading of _Glaucopis wilsoni_! On the

same page Sir Walter Buller also tells us that his "second collection" was

sold to me, but he makes a mistake about the price, as I certainly did not

pay a thousand pounds for it.

I mentioned these unimportant details, because Buller rather bitterly and

severely complained about my describing the Stephens' Island Wren, on p.

111 of his supplement. I may only add that of course my name, being

published in December, 1894, has the priority over his, which was not

published before April, 1895.

The history of _Traversia lyalli_ is perhaps the most extraordinary of any

bird known. All the specimens I am aware of, viz., the eight now in my

collection, the type of "_Xenicus insularis_" in Buller's former

collection, one in the late Canon Tristram's collection, one in the British

Museum (ex Tring), and two or more offered some years ago by Mr. Travers,

were brought in by the lighthouse-keeper's cat. Evidently this feline

discoverer has at the same time been the exterminator of _Traversia

lyalli_, and many may have been digested by that unique cat, as in letters

received from Mr. Travers I {25} have been told that no more specimens

could be obtained, and Buller (l.c.) says: "Very diligent search has been

made on Stephen Island for further specimens of the Island Wren, but

without success, and there is too much reason to fear that this species has

almost immediately after its discovery become extinct."

Habitat: Stephen Island, a small, partly wooded islet, about a square mile

in extent, in Cook Strait. It is almost impossible that this bird has only

existed on Stephen Island. It must have been overlooked on d'Urville Island

or the "mainland," where it probably became extinct--through rats and cats,

and similar pests--long ago.
