NOTES AND QUERIS.

Leptana leevigata, Strophomena peden, Atri/pa reticularis, Rhjnchonella f areata, 
Petraia Una. Tlie only fossil that I am aware of having been found in the 
Pentamerus Kmestone, in this locality, is Pentamerus undatus ; it is a very 
thin band here, and only to be observed by careful search ; it lies about the 
middle of the section. Prom the Caradoc sandstone at the farther end of the 
section, some very fine and perfect Trinucleus concentricus have been observed ; 
several heads (A Ampyx pimiatus, and one entire specimen; fragments of Remo- 
pleurides radiam, Illamis Bamsii, Cali/mene BlimenJjacUi, a new Raphistoma, 
Orthis elerjantida and a new fossil allied to SipJwnetrefa. At the top of the second 
meadow above this place again cross the stream, at a spot where a pole hung by 
a chain is suspended, and on the side of a section of Caradoc sandstone, a new 
fossil Spharospongia hospitalis may be readily observed, as the marks of 
hammers show clearly the exact situation in the cliff where they are to be found ; 
and besides this new fossil, many others belonging to this formation are there 
to be procured. Continue up the stream to Lougviile Common, where a 
quantity of loose stones, of a greenish olive and yellowish brown colour have 
been thrown down from several old quarries above, belonging to the middle 
Caradoc formation. These stones here are rather barren ; still some good speci- 
mens of Modiolopsis orlncularis, BelleropJiOii bilobatus, B. acutus, Strophomena 
expanses, and several species of Orthis may be procured. At the further end of 
the common, cross the river by the stepping-stones, and immediately over the 
turnpike-road leading to Bishop's Castle, is a large quarry of Bala limestone, 
the beds of which are all pitched up perpendicular, owing to several large faults 
in the neighbourhood. The stone is very hard, of a light blue colour, and much 
used for road-purposes ; few fossils have been obtained, being here a rather 
barren rock ; but Mr. Salter, Palaeontologist of the Geological Suiwey, found 
a short time ago a new Liugula, which may be obtained in abundance ; small 
portions of Biplograpsus pristis, some very large Strophomena grandis, witli 
other organisms are to be found. The lower members of tlic Caradoc sandstone 
lie conformable to it on the lower side of the quarry, and some of tlie beds are 
very rich in organic remains ; the best beds are about half way up the bank, 
and may easily be known by the hollows in the side, where the riglit strata 
have been worked, the stone is of a light brown colour, and of a tough sandy 
character. A sharp chissel-shaped hammer is the best for these beds. Some 
perfect Trinucleus concentricus have been observed here, together with a new 
Asaphus; several other Trilobites, which I think are not described ; some very 
beautiful Fenestelke, Bei/richia complicata, and several fossil shells. These beds 
would probably yield several new organisms, if a careful search were made, as 
hitherto they have received but very cursory inspection from geologists. 
About a mile and a half higher up the road, is a hill called the "Broken 
Stones," the lower part of which is composed of the Longmynd or Bottom- 
rocks; and the top of Caradoc sandstone, very poor in fossils. All the rocks 
here are very much pitclied about in consequence of numerous faults. 
From the Bala limestone to the Wenlock shale, which are about two miles 
apart, the road, with the exception just mentioned, passes through the lower 
beds of the Longmynd rocks, from which no fossils have yet been obtained. 
After passing the Wenlock shale, in which no sections are to be seen, the 
road agam passes through the Caradoc sandstone, which continues to the Marsh 
brook ; on the sides are several quarries full of the general remains peculiar to 
this formation. The most prolific section is in the private drive, close to jMarsh 
Brook Station through the coppice to Minton, where a large proportion of 
Caradoc fossils are to be procured. The following are some of tliera that have 
been obtained there: — Tentaculites anglicas, Vhacops conophthalmus, Ilomalonotus 
bisulcntus, Trinucleus concentricus, crinoid plates, species of Fenestella, NebuU- 
pora lens, Orthis unguis, Orthis elegantula, Orthis vespertilio, Strophomena
