Nos. 
186. Eight side of pelvis, hardly distinguishable from that of Ilalniaturus temporalis, the 
Moretou Bay “ Padymelon.” 
187 and 196. Eight mandibular ramus of Phalangista canina (Opossum). [No. 187 sent to 
Queensland Museum.] 
188 and 191. Left tibia of a “Padymelon.” Unlike any existing species available for 
comparison. 
189. Left side of pelvis of Eook Wallaby. Possibly Pelrogale penieillata. 
190. Part of left mandibular ramus of a little W allaby, smaller than any living species known 
to me. [Sent to Queensland Museum.] 
192. Small bone, too delicate for manipulation. 
193. Apparently the outer metatarsal of a Kangaroo Eat. (Compare 185.) 
194. Part of skull of young “ Padymelon.” The nearest living species is Malmatimis stigmaticus, 
of the Cairns district. 
196. Femur of young Kangaroo Eat, of larger size specifically (?) than No. 185. 
197. Upper canine of a large Opossum, Phalangista, sp. 
198. Eight mandibular ramus of a Bandicoot. Very like, if not identical with, Perameles 
nasuta. 
199. Second upper molar, off side of a Horse.* 
It may be remarked that my Colleague has determined four species of Selix, all 
living in the district, as occurring with the bones in the stalagmite deposit of Olsen’s 
and Johannseu’s Caves. The constant association of Eecent land and freshwater 
mollusca with the remains of the extinct mammalia and birds in the drift beds has 
already been noticed. 
From Cape Palmerston to the mouth of the Herbert Eiver, the eastern coast is 
fringed by a strip of alluvial flat, varying in breadth up to thirty miles or more. 
Although apparently level to the eye, it attains an elevation of nearly three hundred 
feet at the base of the Coast Eange west of Townsville. Whether seen on the spot, or 
as delineated on the Geological Map, the first idea of the observer is naturally that this 
alluvial flat is a Eaised Beach ; but, in spite of the presence of beds of clay well fitted to 
preserve fossils, no remains of marine organisms have ever, so far as I have been able to 
learn, been discovered in it. 
Numerous bores and wells have proved this flat to be composed of alternating 
beds of clay, sands, and gravels, the latter being sometimes cemented or consolidated. The 
gravel, which is sometimes very coarse, contains well-rounded pebbles or boulders such 
as probably belonged to river bods. In the neighboin’hood of Townsville, a bore (Bore A) 
at the Hubert Well did not “ bottom ” these drifts at 125 feet; a bore (Twaddle’s No. 2) 
in Portion 100 (Stewart’s Creek) had 101 feet of drift ; and another in the same Portion 
(Tw'addle’s No. 4) had 109 feet of drift. As the sites of these bores are not more than 
thirty feet above the sea, the “ rock-head,” or old land surface, must be from eighty to one 
hundred feet below the present sea-level. No river could possibly have excavated a 
channel to this depth while the land stood at its present level. The land, therefore, must 
have been depressed to or beyond the position at which it now stands with reference to 
the ocean. Moreover, if, as I believe, the alluvia referred to are those of land valleys 
(lakes or rivers), their western walls or rim-rocks must have occupied sites now marked 
by islands in the Pacific or submerged or carried away by marine erosion. Fragments 
of this lost land remain, I believe, in Fitzroy Island, Hinchinbrook Island, the Palm 
Isles, Magnetic Island, Cape Cleveland, Feltliam Cone, Cape Upstart, Gloucester 
Island, and the Whitsunday, Cumberland, Beverley, and Percy Islands ; while a 
submerged range still further to the east may be represented by the Barrier Eeef. 
* The occurrence of the remains of the Horse quite destroys the interest which would otherwise attach 
itself to this deposit from a geological point of view. (B.E. Junr.) j
