natiensis, Rafinesquina alternata, Cyrtolites ornatus, Liospira vit- 
ruvia^ Protowarthia cancellata, Cymatonota pholadis, Byssonychia 
radiata, Calyrnene, and several new species of gasteropoda. The 
horizon is regarded as below that at Pulaski^ but how far is not 
known. The Zygospira above mentioned is the one figured by 
Hallj in the Paleontology of New York, vol. I (plate 79^ Fig. 6), 
probably from Turin^ as Atrypa increhescens. 
With these specimens described from the block found in the 
upper part of the Gulf, west of Turin, the forms of Trinudeus con- 
centricus found in the Rafinesquina nasuta block, west of the rail- 
road bridge, a mile east of Pulaski, and those found in situ at 
Pulaski, Lorraine, and numerous other localities in the middle 
Lorraine, appear to agree perfectly, but better specimens are 
needed for final determination. 
50. Calymene conradi, Emmons 
The following description of Calymene conradi was published by 
Emmons in his American Geology, p. 236, in 1856: 
Small, wide across the cheeks; cheek angles obtuse or rounded; poste- 
rior lobes of the glabella comparatively large and globular; thoracic 
lobes very convex, with a row of tubercles in the furrow or between the 
axis and the lateral lobes. Lorraine shales. 
The fact that this species was described nine years after the 
publication of vol. I, of the Paleontology of New York suggests that 
Emmons, in his description was trying to distinguish the Lorraine 
form from the published figures and description of Calymene sen- 
aria as given by Hall, If so, it will be necessary to establish the 
species upon other grounds than those cited, although it is prac- 
tically certain that the Lorraine form of New York is specifically 
distinct from the Calymene senaria, typically found in the Trenton 
limestone of that state, 
51. Proetus chambliensis, sp. nov. 
(Plate IV, Figs. lA-H) 
The specimens here described (No. 8435, in Victoria Museum) 
lie flattened in a small rock fragment collected on the Richelieu 
River, at Chambly, Quebec, a short distance west of the dam. 
Surface practically smooth under an ordinary lens. In one
