AND THE SURROUNDING DISTRICT. 45 
from the examination of other localities) although highly characteristic 
of the Black River Limestone, are not absolutely peculiar to that for- 
mation (or sub-formation) as was formerly thought to be the case. 
The subjoimed Table gives an enumeration of the fossils collected, 
during my visit, at Belleville and in the surrounding district. 
PLANTS: 
Indistinct fucoids, and at Rednersville an undescribed form pre- 
senting a thick primary stem-mass, with numerous dichotomous 
branchings. 
Corats and Crinoips: 
Stromatocerium rugosum (Shannonville). Stenopora fibrosa (the 
Oheitetes lycoperdon of Hall, &c.): Variety 1, ramosa, the branched 
form, most abundant on the surfaces of the flat layers along the banks 
of the Moira; Variety 2, concava, the flattened or salver-shaped form 
concave above, abundant everywhere, more especially at the Railway cut- 
ting near Shannonville ; Variety 3, globosa, the true “ puff-ball” form, 
rather uncommon. Colwmnaria alveolata (Belleville, Shannonyille). 
Petraia (Streptelasma) cornicula.  Glyptocrinus ramulosus? (stem 
fragments only. 
BRYOZOONS : 
Ptilodictya (Stictopora) acuta, common at most of the fossiliferous 
localities, with a few other (indeterminable) forms. 
BRACHIOPODS: 
Lingula quadrata. .Rhynconellaincrebescens (not common). Stro- 
phomena alternata and S. filitexta (both exceedingly abundant). Lep- 
tena sericea. Orthis testudinaria(also very abundant); O. tricenaria 
(beautifully preserved) ; O. pectinella ; O. lynx (only observed by me 
at Trenton). 
ConcHIFERS : 
Of this Class I did not meet with any determinable forms. 
GASTEROPODS : 
Pleurotomaria lenticularis, Murchisonia gracilis; M. bellicincta; 
M. sub-fusiformis (?) Subulites elongata. 
Prerorops (‘) : 
Conularia Trentonensis (not very common),
