418 CRETACEOUS PELECYPODA 



4. Radtjla insignis, Stoliczka, PI. XXX, Fig. 9. 



Bad. valva dextra magna, crassa, oblique ovata, niodlce convexa costis ^9 majo- 

 ribiisj radiaiitibm, leviter curcatis, sub-tuber culatis, hie et illic minoribus interposiiia, 

 ornata, in declioitate antica et postica sub-obsoletis ; Itimila jjrofmida. 



Only a single valve of this beautiful species has been obtained ; the umbonal 

 part with the upper edges of the ears is not preserved, but the remaining portions 

 are sufficient to show the generic characters of the shell. It is ornamented with 

 nine strong sub-tuberculated ribs and a few less distinct or nearly obsolete ones on 

 the anterior and posterior declivities. Towards the umbo the strong ribs also seem 

 to become less marked, while a number of thinner ribs make their appearance, 

 especially when the outer glassy layer of the shell is decomposed. 



Locality. — Near Moraviatoor, in a sandy limestone. 



Formation. — Ootatoor group. 



5. E-ADULA sp. indet. 



A fragmentary valve of a large species of Badula was found in the coarse 

 conglomeratic sandstone north of Kunnanore. It is of a broadly semiovate shape, 

 somewhat resembling Badula Atibersonensis, Pict. and Camp., (Pal. Suisse, vme ser., 

 4"^' part., pi, 164, figs. 1-2), marked with about 26 radiating, strong, flattened ribs. 

 The umbo and the ears are broken off, and as the shell surface itself also is not 

 well preserved, I shall for the present defer naming the species. 



Formation. — Arrialoor group. 



6. Radtjla sp. indet. PI. XL, Pig. 4. 



Another small costate valve of a Badula (or LimeaJ has been found in the 

 earthy limestone west of Penangoor. It somewhat resembles in general character 

 Llmea Oldhamiana, but the ribs are more compressed and a little more distant ; 

 14 in number. The surface is, however, not sufficiently preserved for a satisfactory 

 determination of the species. 



Formation. — Ootatoor group. 



7. Radtjla interplicosa, Stoliczka, PL XXX, Pigs. 10—11. 



Bad. oblique sub-ovata, infiata, radiatim multicostata, costis majoribiis circa 30, 

 (Bquidistantibus, acutis, antice et postlce multo minoribus, et prope auriculas fei'e 

 ohsoletis, in interspatiis costuUs temiibus alternantibus instructa, costis et costulis 

 minute granulatis ; area ligamentali valde declivi, medio triangulariter excavata. 



Shell obliquely ovate, tumid, ornamented with about 30 sharp ribs which al- 

 ternate with much thinner ones ; on the anterior and posterior declivity the ribs 

 are finer, and near the cars they become almost quite obsolete : aU the ribs are 

 finely granulated.
