Genus Alveolites Lamarck, i8ci. 
Alveolites sp. aff. suborbicularis Lamarck. Plate LVIII., fig. 30. 
This specimen is a fragment measuring 26 by 8mm. It is attached 
to a layer in the coral mud matrix by its flat side. The only indication 
of internal structure within the cells is a thick septum in one or two, re¬ 
calling a similar feature in Alveolites suborbicularis Lam. 1 2 of the Middle 
Devonian of the Eifel. True septa, as in Alveolites labechei Edw. and 
Haime 3 of the Wenlock, seem to be absent in this example; and, alto¬ 
gether, the affinities seem to be closer to the Devonian species above named.. 
The oorallites in the Deep Creek specimen increase rapidly in size from 
the base of attachment to the distal surface, and measure from 1 to 3mm. 
in transverse diameter. 
Fam. Fistuliporidae. 
Genus Fistulipora McCoy. 
Fistulipora victoriae, sp. noy. Plate LVIII., fig. 31 ; pi. LIX., figs. 32-34. 
Description. —Corallum somewhat massive, ramose, subcylindrical or 
expanded; length in present type, 6.5cm. ; formed of successive layers of 
oorallites, 3 to 6mm. in thickness j corallites of two kinds, thin walled. 
The autopores are subcylindrical, and average 2mm. in diameter; in ver¬ 
tical section they are seen to be divided by more than usually numerous, 
tabulae, which are curved and concave towards the outer surface of 
corallum, and generally 0.3mm. apart. The mesopores are as large, or 
larger, than the autopores, polygonal, and arranged radiately around the 
autopores; in vertical section they are in single, or in two or more series, 
according to their relation to the autopores, but generally double, and 
numerously divided into low, subangular cells, by curved (convex) tabulae 
or partitions; average diameter about 0.25mm. Occasional maculae of 
twice the diameter of the autopores. 
Affinities. —Perhaps the species nearest to ours is F. lockporteusis 
Bassler, from the Niagara Limestone (Wenlockian) of Lockport, N.Y. 
State. 3 In that species, the autopores measure 0.5mm. in diameter, im¬ 
parting to the corallum a coarser structure; whilst the tabulae are very- 
rare, or altogether wanting. 
Observations. —This genus has been before noted from the same series 
of limestones (Wenlockian) in Victoria, from the Thomson River, Gipps- 
land 4 , but the specimen was not sufficiently well preserved for specific 
identification. Enough can be seen, however, to show that it differs from 
the present form, and it was probably of a more frondescent type of 
growth. 
Occurrence .—Griffith’s Quarry, Loyola.
