the Phillipsburgh group containing a few forms recalling the 
second fauna, a sort of precursory center of apparition of the 
second fauna; and that the Rutland marble belongs to the lower 
division of the upper Taconic system. 
At Sudbury, Wing found in situ, in a lenticular mass of lime- 
stone inclosed in a "great central belt of slates" a Trimicleus 
concentricus. If the determination is exact, we have here a 
colony of the second fauna inclosed in the Swanton slates, as 
at Highgate Springs. 
At Eastern Oswell, and Shoreham, Whiting and Cornwall,. 
Wing found: Stenopo7-a fibrosa, i\.\\(\ St. petropolitana, Recep- 
taculites ncftuni, Columnaria alveolata, Maclurea matutina 
and Alac. sordida, Ophilcta cottiplanata and Oph. cajnpactUy 
Bathyiirus saffordi (very common at Phillipsburgh and at 
Pointe Ldvis), Bathyurus extans and Bathyurus conicus, Asa- 
phus canaJis and Trinucleus concentricus ^\x\ all thirteen species- 
determined, showing a mixture of the second fauna with the pri- 
mordial fauna represented by three ^«/^jj/«r/. Besides, a certain 
number of fossils were collected, which are referred to only by 
generic names, such as Orthis, Orthisina, Orthoceras, Petraia,. 
Holopea, Rhynchonella, Strophotnena and encrinal disks, show- 
ing also a mixture of second fauna forms with primordial forms.. 
The Bathyurus is very numerous and also the Maclurea. I 
saw those two genera at Shoreham in 1862, and I referred the 
strata there as belonging to the Phillipsburgh and Pointe L^vis- 
group of the upper Taconic. At North Cornwall, Middleburg 
and Weybridge, the fossils recorded by Wing are.* Bathyurus 
saffordi and Bathyurus angeliiii, Asaphus canalis and Rete- 
pora incepta, four species in all, with a certain number of 
undetermined species belonging to Maclurea, Murchisoniuy. 
Orthoceras, Rhynchonclla, Orthis, Leperditia and encrinal 
stems. A fauna of the Phillipsburgh and Pointe L^vis group ^ 
At a few other localities, Orthoceras, Maclurea, Murchisonia^ 
Rhynchoticlla, Orthis, and Ophilcta are mentioned by him. 
In all we have only eleven species of the second fauna, repre- 
senting corals, gasteropods and a single trilobite, Trinucleus 
concentrictis, mixed with four species of very common and 
characteristic supra-primordial trilobites, Bathyuri; and we 
have not a single Lamellibranch, nor a fragment of any of the
