1889.] MR. A. P. GOODWIN ON SOME PARADISE-BIRDS. 451 
of the head and the trunk are described under the name of Squatina 
erassidens (Catal. Foss. Fishes B. M. pt. i. p. 69, pl. ii.); they are 
broad and acuminate, compressed antero-posteriorly, and fixed upon 
a depressed base; the crown is marked by large vertical wrinkles, 
and its median portion is produced downwards anteriorly over the 
root. In its dentition, Sclerorhynchus thus approaches the living 
Pristiophorus more closely than Pristis, though differing from both 
these types in the striation of the dental crown. The arrangement 
of the rostral cartilages, however, is sufficient justification for still 
retaining the extinct Cretaceous genus in its provisional position 
among the Pristidee, of which it is the least specialized type hitherto 
discovered.” 
Mr. A. P. Goodwin laid on the table examples of some rare 
Paradise-birds procured during Sir William Macgregor’s recent 
expedition to Mount Owen-Stanley, New Guinea; also several 
photographs, comprising views of Mount Owen-Stanley, of a native 
bridge, and of the bowers of some species of Bower-birds met with 
on this occasion. 
Mr. Goodwin made the following remarks :—‘‘ The most note- 
worthy of these birds is a pair of Hpimachus macleayane, lately 
described by Dr. E. P. Ramsay, Curator of the Australian Museum, 
Sydney, in the ‘ Proceedings’ of the Linnean Society of New South 
Wales, ser. 2, vol. ii. p. 239. The type specimen was obtained 
some two years previously by one of Sir William’s party in the 
Maroka district. This Hpimachus inhabits the mountain-regions 
of this district at an altitude of from 6000 to 9000 feet ; above that 
no Paradise-birds were found by the party, save one Bower-bird 
which I will mention hereafter. 
“The call of EZ. macleayane is a shrill double-note, similar to the 
sound produced by striking a pair of clappers together. 
“The next bird is a female of Astrarchia stephanie, which was 
originally discovered in the same locality. Not -having been so 
fortunate as to see this bird alive, I am able to give you but little 
information about it; but it is somewhat remarkable that no speci- 
mens were obtained after the party had been in camp two days, 
nor was there any adult male seen by any of the party. 
‘«‘ Among the photographs taken on this occasion are :—A view of 
Mount Owen-Stanley, taken from Mount Musgrave, at a distance 
estimated at eight miles; also one of a tribe of the natives who live 
in the mountains; and one of a native bridge, 195 feet long, which 
spans the Vanappa River. I also call your attention to two 
interesting views of Bower-birds’ bowers. One of these belongs to 
Amblyornis subalaris ; and the other, found at a higher altitude, up 
to 10,000 feet, is of a species which I propose te call Amblyornis 
musgravii. Several specimens of this bird were obtained. It is 
similar to, but larger than, 4. subalaris, which was procured on- 
Mount Belford at an altitude of 4000 feet.”
