Raphistomina uiidulatiim s]). nov. 



Shell small, having four or five whorls; lenticular; the spire 

 rather high, and the under portion rounded, depressed, not subcon- 

 ical as in Raphistoina stainineiDii. 



The surface of the first three or four volutions, in the cast, is 

 smooth, but marked by numerous small folds which run from the 

 suture diagonally forward across the surface of the volution. The 

 margin is acute, rounded and just beneath the margin is a narrow con- 

 cave space. Below this the shell is gently convex for a short distance, 

 then flat to the umbilicus, which, in the cast, is open. 



Locality. — This shell has, so far, been found only in the middle 

 Chazy at Sloop Bay, Valcour Island, New York. 



Bticaiiia catilloides sp. nov. 



Shell very small, compressed, with two or three whorls which ex- 

 pand gradually. The carina is narrow but distinct and slightly ele- 

 vated. The form is much like that of Belleroplion acutus Hall, but 

 the umbilicus is wide enough in the present species to expose all the 

 whorls. On none of the specimens are the surface markings preserved. 



Locality. — ■ A very rare fossil found so far only on the west side of 

 Valcour Island, where it is associated with Biicauia siilcatina, Zygo- 

 spira aciitirostris and species of Phylloporiiia. 



Eccyliopterus kalmi sp. now 



Shell small, loosely coiled ; apex acute, incurved, but not making 

 a closed volution. The shell is roughly rectangular in cross section, 

 flattened on top, sloping outward and downward on the side and ob- 

 tusely angulated at the lower angle ; rounded below and on the inside. 

 The specimen is a cast and does not show any surface markings. 

 This species may be separated from both Eccyliopterus fredericus and 

 Eccyliopterus proclivis by its subrectangular cross-section. 



Locality. — A rare fossil at Sloop Bay, Valcour Island, in the middle 

 Chazy. Named for the explorer and naturalist, Peter Kalm, who visited 

 this region in 1749. 



Eccyliopterus proclivis sp. nov. 



Shell loosely coiled, apex acute, scarcely incurved. Cross-section 

 of cast triangular. Upper surface flat, the lower acutely angulated. 

 Both inner and outer sides are gently convex. The cross-section of 

 this shell easily separates it from the preceding.
