side. One specimen is 28 mm. high and 22 mm. in greatest diam- 

 eter ; the spire is 7 mm. high. In the same specimen the transverse 

 diameter of the aperture is 13 mm. and the antero-posterior diameter 

 is 14 mm. A second specimen is 24 mm. in height and 20 mm. in 

 diameter. 



Locality. — This species is rather common at Crown Point, Valcour 

 Island, and Chazy, New York. The original of figures 1 and 2, Plate 

 LIV, are in the Yale University Museum, and the original of figure 

 3 in the Carnegie Museum. 



Genus Eunema Salter. 

 Eunema alti sulcatum Hudson. 



Eunema altisulcahim Hudson, 1905, Report New York State Paleon- 

 tologist for 1903, p. 291, PI. 5, fig. 3. 

 This species is not represented in the collection studied by the 



writer, and it has been described so recently that the description is not 



repeated here. The species occurs in the Chazy Limestone at Valcour 



Island, New York. 



Eunema epitome Hudson. 



Eunema epitome Hudson, 1905, Report New York State Paleontologist 



for 1903, p. 290, PI. 4, figs. 6, 7. 



This species, which has been very fully described by Hudson, 

 occurs in the Chazy on Valcour Island, New York. 



Genus Gyronema Ulrich and Scofield. 



Gyronema historicum (Hudson).

Eunema historicum Hudson, 1905, Report New York State Paleontolo- 

 gist for 1903, p. 288, PL 4, fig. 5. 

 Cyclonema ? normaliana Raymond, 1905, American Journal of Science, 

 Series 4, Vol. XX, p. 377. 



An examination of Hudson's figure and description of Eunema 

 historicum has convinced me that Cyclonema ? normaliana Raymond 

 was founded on larger and more complete specimens of the same 

 species, with, however, the detail of surface markings less perfectly 

 preserved.
