TRANSACTIONS OF THE SECTIONS. 97 
dogs, horses or cows, bears, hyzenas, rhinoceros, and also the tooth of 
a tiger, found in a bed of diluvium which fills a cave of the carbon- 
iferous limestone at the Cefre Rocks in Denbighshire, in the estate of 
Mr. Lloyd of Cefre, about three miles from St. Asaph. 
__ Mr. Gilbertson placed on the table many very interesting, and pro- 
bably new fossils from the mountain limestone, and Mr. Dawson a 
collection of fossils from New South Wales. 
ZOOLOGY AND BOTANY. 
Mr. Gould exhibited drawings of new Birds from Australia and 
other parts of the world. He proceeded to make some remarks on the 
family Trogonide. This family, he stated, might be regarded as strictly 
tropical, and by far the greater number of species inhabited South 
America ; none of those inhabiting Asia and Africa having any specific 
relation to those of America. It is a remarkably isolated group, no 
_ direct affinity with other forms having been discovered. In organiza- 
tion and economy they are perhaps nearest the Caprimulgide. They 
_ inhabit the most retired and gloomy forests, remaining secluded during 
the day, and appearing at night ; evening and morning being the only 
_ time in which they take their prey. They usually feed on insects, 
capturing them during flight, but sometimes they feed on berries. 
_ They incubate in the holes of trees, and, like the majority of Fissiros- 
_ tral birds, produce white eggs. The tribe present among themselves 
_ but little difference of structure. There are, however, well-marked 
divisions according to their geographical range. Mr. Swainson divides 
_ them into five minor groups, 7rogon, Harpactes, Apaloderma, Tem- 
_ nurus, and Calurus. The species of bird that Mr. Gould presented be- 
_ fore the Section belonged to the latter group, and he proposed to call 
it Calurus Peruvianus. This sub-genus comprises the most beautiful 
_ birds of the whole family, and perhaps in the creation ; it contains five 
_ species, only one of which until lately had been characterized. The 
present species, although it has not the lengthened upper tail-feathers 
_ of the C. resplendens, (which was exhibited), yet its relations to that 
species were sufficiently obvious. For this species he had been in- 
_  debted to the researches of the indefatigable and scientific French tra- 
_ veller, M. D’Orbigny, who had recently returned from Peru. 
On Filaria. By the Rev. W. Hore. 
_ In this communication more than forty genera of insects were 
mentioned in which these parasitic worms had been found, and tables 
'_ were exhibited containing the names of all the authenticated species, 
and authorities given for all the recorded instances, as well as could 
be ascertained.
