168 CRETACEOUS PELECYPODA 



strite are partially traceable on au imperfect specimen in our collection (pi. xvii, 

 fie. 4), but I have not been able to see them on Forbes' original, of which I have 

 also o-iven a view. On the former, the hinge-teeth of the right valve were observed, 

 thou"-h on account of the difficulty in preparation they became somewhat less 



distinct. 



For the sake of comparison, and also in order to illustrate the hinge of 

 Barocla and its sub-genus Icanotia, I have given a view of the hinge of Barodu 

 [Icanotia] imjxir, Zittel, sp., on p. xvii, fig. 5. It would be very interesting to 

 examine more perfect specimens of this species. 



LocaUty. — Moraviatoor, in a dark earthy limestone ; apparently rare. 



Formation. — Ootatoor group. 



2. Baroda [Icanotia] elicita, StoUczka, PL IV, Fig. IG. 



Bar. testa perlonga, valde comj^ressa et incequilaterall ; parte anteriori brevi, 

 ad terminationem angitstatbn rotiindata, postice oblique ac late sub-truncata ; inuboni- 

 bus parvulis, decUoitate Immlari rectiuscula, areali fere concaviuscula, perlonga ; 

 margine ventrali levissime curvato ; superficie liris dejjressis latitiscidis, concentricis 

 ac costulis radiantibm tenuibus, confertis, imprimis in parte p)Ostica distinctis, 

 notata. 



Median height : length ... ... ... ... 0-34 



Thickne.ss : height ... ... ... ... 0'61. 



This species closely resembles the one described by Zittel from the Gosau 

 deposits, B. \IcanoVui\ impar, but the posterior end is more truncated, and the 

 radiating ribs finer ; the latter character easily distinguishes also the Indian fossil 

 from any of the forms photographed by Gueranger. The hinge-teeth must be 

 very thin and small. I have not been able to trace them on any of the two 

 specimens in our collection, with the exception of a thickened margin seen 

 internally along the lunula, such as I have, however, not observed in any of the 

 other species of Icanotia. 



Locality. — North of Karapaudy, in a whitish, highly calcareous sandstone ; 

 apparently rare. 



Formation. — Arrialoor group.
