240 Reports— Geological Sorreny of London. 
The author referred to the little attention the Jurassic Polyzoa 
have received in England, a few scattered papers comprising the 
whole of the literature of the subject. This may be accounted for, 
in part, by the rare occurrence of conditions favourable to the pre- 
servation of the delicate features necessary for their true study, and 
in part, also, by the difficulties into which the classification has 
drifted. 
The series dealt with has been collected from the Inferior 
Oolite, zone of Ammonites Parkinsoni, at Shipton Gorge, Dorset, and 
the number of forms from the single horizon and locality was stated 
to be equal to the whole of those described by Jules Haime from 
the Lias to the Kimeridge Clay. Associated with the Polyzoa are 
Crania Moorei, and sp., Thecidea, sp., Rhynchonella senticosa, Tere- 
bratula Phillipsii, Ammonites Martinsii, some Hchinoderms, and a 
large series of sponges. ‘The tranquil conditions prevailing during 
the deposition of the beds are indicated by the presence of many 
slender and arborescent forms of Polyzoa, and the little abrasion 
they have suffered, as well as by the presence of numerous sponges. 
The author, in briefly reviewing the Cyclostomata, adopts the 
simple divisions of Mr. Waters, the Parallelata and Rectangulata, 
based upon the Hincksian system. The disregard of zoarial growth, 
in any great degree, as a means of classification, would lead to con- 
fusion under the present modes of grouping; neither, however, can 
any great constancy be found in the form of the zocecia or in the 
shape of the aperture. 
In the group Stomatopora six species are recognized, of which 
two are new. Amongst the Proboscing is a species described in 
that stage of growth as Proboscina spatiosa, which passes into both 
Tubuliporoid and Diastoporoid forms, and also in the latter phase 
throws off erect Entalophoroid branches. The author has used the 
same specific name for each form, though describing them under 
different generic names. Considerable variation in size and shape 
of cell occurs in each stage. The Idmonee are represented by two 
new species and two new varieties; Lisidmonea by one form only. 
Though the latter has much the appearance of Hntalophora, the 
character of the ovicell is so definitely that of the associated Idmonea 
as to decide its relationship, and it has also the cell-type of Idmonea. 
In the group Entalophora d’Orbigny'’s Cretaceous species Hnéalo- 
phora raripora and £. subgracilis are quoted, the latter, however, 
under a varietal form. EH. anomala, Manz., EL. richmondiensis, Vine, 
and one new species, H. magnipora, complete the list so far. 
MISCHIDANHOUS. 
Western Avstratia.—From Reports received, it appears that 
the Gold-fields of this Colony are likely to prove as rich as those 
of Eastern Australia. But we are still more glad to learn that the 
Coal-seams on the Irwin River, noticed by Gregory in 1863, are 
now being successfully worked, and promise excellent results. 
Western Australia has already 450 miles of railroad, and if coal 
can be obtained close to the northern terminus at Geraldton, it will 
be of the highest value.
