25. Corhula velata, Scliafli., is according to Gllmbel (Neues Jalirb. f. Min- 

 eralogie, &c., 1865, p. 149), identical witli Crassatella JPenana, Glimbel, an eocene 

 species, (Bayer. Alpengeb., 1861, p. 662). 



Instead of C. velata read under No. 25, Corhida siibelegans, Briart et Cornet, 

 (Descript. mineral., &c., de la meule de Bracquegnies, p. 82, pi. v, figs. 17 and 18, 

 in Mem., Cour. Acad. Belgique, vol. xxxiv).

 On page 69 under No. 32, PUcomya, StoL, 1870, note — 



Conrad (Am. Jour. Concb., vol. VI, p. 76,) proposes to substitute for bis name 

 Leptomya tbat of Feriplomya. I do not know tbe exact date of issue of Part I 

 of vol. VI of tbe American Journal of Concbology. My name FUcomya, svibstituted 

 for Conrad's Leptomya, was publisbed on 8tb September 1870, altbougb tbe por- 

 tion of letter press containing it was already printed about tbe end of January of 

 tbat year, and tbe MS. bad been prepared at least one year prior to it. 



Conrad adds tbe figure of tbe binge of tbe type species (Feriplomya) peculiar is, 

 Conrad, (quoted on p. 73 sub-No. 39). From tbis it would seem as if tbere were 

 a tbick, oblique tootb in tbe left valve passing at its base into a tbickening of tbe 

 posterior binge margin, a fissure would seem to extend from tbe beak posteriorly ; 

 of tbe otber rigbt valve only a median spoon-sbaped process is figured below tbe 

 beak. It is possible tbat I may be mistaken in tbe interpretation of rigbt and left 

 valve, but tbat would not be supported by Conrad's reference on p. 76 loc. cit. 

 If I am, bowever, correct in tbe interpretation of tbe figures, tbe form could bardly 

 be considered as sufiiciently distinct from Anatina.

Page 88, No. 59. Tbe name Fanopma Sancti-Fetri, Ryckbolt, is cbanged by 

 Bosquet into P. Byckholti, (Liste des foss. du mass. cret. du Limbom'g, 1868, extr. 

 du descript. geol. de la Belgique par Devalque, p. 17), but tbere is no necessity 

 for tbis cbange. I bave, bowever, accepted tbe suggested cbange of a specific 

 name, wbere it designates two distinct objects to wbicb tbe species is referred, sucb 

 as " montis sancti Fetri."
