NAPLES FAUNA IN WESTERN NEW YORK, PART 2 301 



crossed by very fine, elevated, retrally curved striae, which become crowded 

 toward the periphery. The striae also cross the furrows with a downward 

 curve and, though faint are clearly retained on well preserved sculpture 

 casts. Concentric periodical depressions frequently mark the surface, inter- 

 rupting the ribs and at times making a conspicuous feature. 



The species is well characterized and readily distinguished by its size 

 and surface characters. It is among the rarer forms of the genus. 



Dimensions. Length and width of an average example 13 mm. 



Habitat. Genesee province ; Chautauqua subprovince. In the soft 

 shales at Angola, Erie co., and on Farnham creek, 3 miles southwest of. that 

 place. 



Buchiola lupina sp. nov. 



Plate 10, fig. 34-36 



Shell quite small, obliquely oval, notably narrowing anteriorly. Car- 

 dinal line straight, anterior angle large. Surface regularly convex, not 

 greatly elevated in sculpture casts ; depressed abruptly in front, more grad- 

 ually behind; with 11 to 13 rounded ribs, slightly depressed above, and 

 with narrow, shallow, intervening furrows. The concentric lines are fine, 

 sharply elevated and closely crowded and on the ribs make a low and broad 

 retral curve. These striae are continued over the furrows with a downward 

 curve of about equal strength, but they are less sharply defined on these 

 areas. In this respect the sculpture of the species is like that of B. an-go- 

 1 e n s i s, but there is a notable difference in the species in form, size, and 

 number of plications. 



Dimensions. Length of an average specimen 5 mm. 



Habitat. Genesee province ; Naples subprovince. From the soft 

 shales at the mouth of Wolf creek near Mount Morris, in the lower Genesee 

 valley. Chautauqua subprovince. At Pontiac, Erie co.
