OE SOUTHERN INDIA. 161 



33.— r. sub'ToUncla, d'Orb., (rotunclata, Sow.^) is a Caryatis. 



33-34. — VAmmersa ^Vi^sullmis oi Sowerby both are probably '(T^^/^^/"^^; the former could 

 also be an oval Ci/primeria, 



35-36. — r. suh-truncata, d'Orb., (truncata, Sow.), and V. stthmersa, Sow., belong to Caryatis, 



37.— r. ,,, = Ve7ius faha, Sow., apud d'Orb. This may be identical with our Indian Cytherea 

 \_CaUista\ fahulina (see p. 174). 



38.— r. Cenomanensis, d'Orb., is Baroda fragilis, (d'Orb.), belonging- to the sub-family 

 TAPEsm^, and described by Zittel as Tapes fragilis, d'Orb., sp., from the Gosau (vide Denksch. 

 Akad.^Wien, 1865, vol. xxiv, pt. ii, p. 122, pi. iii, %. 3). 



39. — V. Botomagensis, d'Orb., apparently a Caryatis, 



40. — V, Astieriana, Math., most likely a true CytJierea, 



41. — V. Lahadyeiy d^Arch., a / Caryatis, or Cyprhneria, 



42.— r. Renauxiana, d'Orb., was proposed for the form referred in the Pal. frSn9. to 7, plana, 

 Sow., and is said to differ in being much more compressed than this. No reference is made to the 

 figures, or any special description, and no opinion can, therefore, be pronounced without the originals. 



43.— r. Noueliana, d'Orb., is said to be allied, but more tumid than Cyth. plana. 



44. — r. Martiniana, Math., is a 'Paratapes of the tapesin^, and ought to stand as Faratapes 

 Imigata, Sedg. and Murch. (see Zittel in Denksch. Akad., Wien, xxiv, pt. ii, p. 123). 



45. — V, suh'lenticularis, Haime, is evidently a (7yj!9rmm^, in which the middle tooth of the 

 right valve is bifid, unless it is a slight deficiency of the drawing. 



46.— r. cuneiformis, Duj. The impressions on the cast, as seen in the figure 5^, appear to 

 be those of a Cyprimeria ; it is a somewhat oval form. 



47. — r. jueunda, Duj. This is one of the very few cretaceous forms I know, the ornamenta- 

 tion and solid shell of which closely resemble Venus proper, but the specimen is so imperfect 

 as not to allow of a correct determination of the genus ; it could with almost equal probability 

 belong to Linearia of the tellwid^, 



48. — Y, suh-plana, d'Orb., is said to be again difierent from the V, plana in the Pal. fran9., 

 vol. iii, pi. 386, figs. 1-3 (vide p. 160 and p. 169). 



49. — V. Boy ana, d'Orb., probably a Baroda, or another genus of the TAPESIN^. Schaf hteutl 

 (Siid-Bayerns Leth. Geog., 1863, p. 171, pi. xxxviii, fig. 3,) figures under this name a shell 

 which I hardly believe could belong to this species, but much more probably to the Myid^. The 

 ideas indicated of the conchological value of a species are quite as singular as those of geological 

 formations ! 



50. — V, ArcJiiaciana, d^Orb., is most likely an elongated Cyprimeria, 



51. — V. Lamar chi. Math., may either be an Eripliyla or an Astarte, 



52. — V. late-sulcata, Math., ? a Callista. 



53. — V, ovum,^ Math., mostly resembles such recent forms as Tapes meroeformls. Sow., 

 which belongs to a special section of Pullastra, 



54. — V, turgida. Math., (suUurgida qy pseudoturgida, d''Orb.,) is most likely a Caryatis, 



55.— -F. Lapeyrousana, Leym. 



56. — Artemis elegantula, Sharpe, is most probably a Cyprimeria, 



Pictet and Campiche have, I believe, very good reason to hesitate in giving a list of the Ger- 

 man and Bohoemian and other cretaceous species, on the ground that the identification of these with 

 foreign species may not be correct. I have myself seen a good many of them ; but unless one under- 

 takes the difficult task of searching after the originals and is successful in this, nothing positive 

 can be said regarding the correctness of these determinations, or otherwise. 



57. — V, suh-ovalis, d^Orb., (V, ovalis, Goldf, Nucula concentrica, Gein.,) must stand as 

 Cytherea [^Caryatis] ovalis, Goldf., sp, I have examined very good specimens of both valves received
