 vertical view, and 15, outline profile of the type. { To these 

 are added Hgs. 16^ 17, of Cliospira lirata, WhMeld, from the 

 same plate.) Of the type of R. Ie7iticularis, Sow.; generally 

 like Pleurotomaria canadensis., Billings, Pal. Foss, I, f. 328, 

 but more compressed, and with fewer whorls ; probably most 

 like jP.Aar^ya, Bill. FortOassin, Vt. Bird'' s eye limestone. lie. 

 Note. — Whitfield's figs. 16, 17, above, are of a single speci- 

 men of a curious sinistral, trochiform gasteropod shell, found 

 with the Eaphistomas., etc., which he places in Billings' genus 

 Cliospira of the Quebec group near St. Antoine ( C. curiosa^ 

 Bill.) and names it C. lirata., because its surface is marked by 

 strong, oblique, lamellose ridges, parallel to the margin of the 

 aperture, or crossing the whorls obliquely backwards, and sep- 

 arated by grooves, like no other species of this genus. Com- 

 pare also Whitfield's Wisconsin species C. occidentalis (Geol. 

 Wis. IV, 1876) which he finds identical (?) with Lindstrom's 

 Swedish Onychocheilusreticulatum. (Kong. Sv. V. A. H., XIX, 

 No. 6, p. 196.)
