OF SOUTHERN INDIA. 287 



Sow.^ and quotes besides A. substriata, Leym. = pseado-striata, d'Orb. Pictet and Campiclie 

 (Pal. Suisse, 4™^ ser., 3"^^ part., p. 322,) add from Lynch's exped. A. lintea and sub-lineolata of 

 Conrad. 



125. — Astarte corhicula, Con., (Am. Journ. Conch., iii, p. 12), is changed by the same author 

 (American Journ. Conch., V, p. 43,) into Vetocardia crenalirata, Conrad ( ?^= Astarte crenulirata, 

 Lea). I have already noticed the strange association of fossils which Mr. Conrad first quoted as 

 species of bis genus Vetocardia, but even those which he subsequently regards as typical of that 

 supposed genus are, I believe, as regards character of the hinge, not distinct from his Falaeocardita, 



126 127. — Gouldia decemnaria and declivis, Con., (Am. Journ. Conch., v, p. 48), are from 

 New Jersey. 



128-130. — The following species occur in the South Indian cretaceous deposits : Grotnania 

 jugosa, Gouldia planissima, and G. trigonioides. 



Cardita (see Pal. Suisse, 4™^ ser., 3""® part., p. 339). 



The distinctions between Cardita and MytUicafdia can only be indicated from the external 

 shape of tbe sbells ; wbicb of them should be referred to Venericardia it is for the present quite 

 impossible to say. If we have to go by the comparison of recent forms with fossils, (and there is 

 no better course to be adopted), there certainly appear to be very few cretaceous G^/r/i?^^. 



131-138. — C. Sanctce-crucisj Neocomiensis, quadrata, Fillersensis, Stahileana, Orhignyana, 

 Valdensis, fenestrata, are forms which are closely related to Mytilicardia ; it is possible that 

 Conrad^s name Palaocardita may be more appropriate for them (vide p. 280), but I have no 

 good specimens of any of these species for examination. C. fenestrata is not unlike a Venerupis. 



139. — C. Meriani resembles in form Tleiiromeris^ and also Pteromeris, of Conrad. 



140. — C. Gurgyacensis. 



141-152. — C. Bupiniana, (see p. 280), exaltata, tenuicosta ( ? = Fe?ie?'icardia tenuicosta, 

 Sow, apud Fitton), clathrata, rotmidata, Constantii, Argone?isis, Cefiomanensis ^"^ dubia, Guerangeri,^ 

 tricarinata ,^ Cottaldina, are all of the same type and have to be referred either to Mytilicardia 

 or to Palaocardita. 



153-154. — C. parvida SiTidi semistriata mdij h^ tv\\Q Mytilicardia, hxxi the specimens figured are 

 very imperfect. 



155. — C. Genitzii, (Ten. tenuicosta, Sow., apud Geinitz) is a peculiar form which should be 

 carefully examined whether it belongs at all to the present group of shells. 



156. — C. granigera is either a true Cardita, or possibly a Pteromeris. 



157. — C. Reynesi is a true Mytilicardia. 



C. biloculata is an Opis (see p. 284). 



158. — C. Hebertiana is said to be a quadrangular, ribbed species ! 



159. — C. pinguis, Coquand, Mon. iStage Aptien de FEspagne, 1866, p. 122. 



160-164. — C. ForgemolU, Nicaisei, Delettrei, Beuquei, and Bocchi are described by Coquand 

 from Algiers (Geol. and Pal. de la Prov. Constant., 1862, pp. 199-201, &c.). 



165-172. — C. eminula, subqttadrata, and subtetrica are from North America (see Meek''s Check- 

 list of cretaceous fossils. Smiths. Misc. Coll., No. 177, 1869, p. 11). Conrad has besides from the 

 so-called lower eocene (? cretaceous) beds Venericardia Blandingi, densata, Hornii (= planicosta, 

 Con., an idem Lam.)t, perantiqua, and regia (see Check-list eocene foss.. Smiths. Misc. Coll., 

 No. 200, 1866, p. 5). 



173. — C. veneriformis, Gabb, Pal. Calif., i, p. 215 ; (?) C. alticosta, Gabb, (ibid., vol. ii, p. 268). 



174. — Cardita Jaquinoti, d'Orb., is the only species which occurs in Southern India.
