OF SOUTHERN INDIA. 165 



IQQ.— renus glabra, Schafhffiutl (Siid-Bayerns Leth. Geog., 1803, p. 171, pi. 43, fig. -I), 

 has the general form of a small Ci/tkerea or Merceiiaria, but I am afraid further ideutification is 

 hopeless. 



From Africa the following species have been recorded, mostly based upon insufficient casts. 



110-120. — Venus Dutrugei, Cleopatra, Monsce, Rei/nesi, Manritaiiica, Desvauxi, Lelettrei, Nail, 

 Forgemolli, Bidonis, Fatima, Cherbonneaui, and Saporfa of H. Coquand (Constant, pp. 193-195), 

 nearly all from the " etage Rotomagien." It would be a vain task to speculate upon the correct 

 generic determination of such worthless materials. Most of them may be C^therea and Caryates, 

 some like V. Beleltrei and Forgemolli belong to Cijprimerid or perhaps to Friphyla. 



The following are from America. 



131-143. — Ci/elina ? circularis, M. and H. ; ( DosiniaJ Cyprimeria densata, Con.; Bos. 

 d^epressa, Con.; (Bos.) Cyprimeria excavata, Morton; Bos. ]Iaddonficldensis,\iQ^ =^ Cyprimeria 

 cretacea, Con., (Am. Journ. Conch., iii, p. 9); Bos. ohliquata, Con.; Bos ? tennis, Meek; 

 Bione Belawarensis, Gabb ; B. Eiifalensis, Con.; D. Lamarensis, Shum. ; B. Beweyi, M. and 

 H. ; B. leonensis. Con.; B. ilissoitriana, Mort. ; B. Ncbrascensis, M. and H. ; B. orhl- 

 ciilata, H. and M. ; D. Owenana, M. and H. ; B.? pellucida, M. and H.; (B.) Texana, 

 Con. f= i' Cyprim. Texana, Rom.); B. tippana. Con.; B.? Meekana, Gabb.; B.? Ripley - 

 awfl, Gabb; B. ? tenuis, Hall and M. ; Venus ? suh-lamellosa, Shum. (Vide Meek's Check-list 

 of Inv. N. Am. fossils, Smith. Misc. Coll., No. 177, 1864, p. 13). 



144-159.— From Conrad's " Check-list", &c., (,Smith. Misc. Coll., No. 200, 1866, pp. 6, &e.), 

 that author's older eocene species probably have to be added — Bosinioj)sis alta, Con. ; B. 3Iee/cii, 

 Con.; B. lenticularis, 'Rogers, Venus.'' lamelli/era, Con. ; V. securis, Shum. ; Bione bremlineata. 

 Con.; D. Conradiana, Gabb; B. Calif orniana , B. eversa, lenis, liciata, Oregoueusis oi Conrad, 

 B. ovata, (Rogers) ; B. perbrevis and Uvasana, Con., and B. varians, Gabb. 



160-181.— In the 2nd vol. of the Palajont. of California, pp. 209, &c., Gabb gives a list of 

 all Califomian cretaceous fossils. In this list, besides those given already, some of the species 

 having been previously described by the same author in vol. i of the same publication, occur — 

 V. Veatchii, G. ; V. lenticidaris, G. ; V. fefra/tedra, G. ; V. aqiiilaieralis, G. ; — Chione angulata, G. ; 

 Ch. varians, G. ; — Meretrix (^ Cylherea) lens, G. ; M. Ilurnii, G. ; M. longa, G. ; M. arata, G. ; 

 M. ovalis, G. ; M. ? fragilis, G. ; — Caryatis nitida, G. ; — Bosinia elevata, G. ; ? B. tenuis. Meek; 

 B. pertenuis, G. ; B. gyrata, G. ; B. injlnta, G. ; — Tupes Conradiana, G. ; ? T. quadrata, G. ; .' 

 T. cretacea, G., and Eriphyla umbonata, Gabb. 



182. — Tapes Hilgardi, Shum., (vide Gabb, 1. cit., p. 265,) only provisionally referred to Tipes, 

 is from Mexico. 



183. — Cyprimeria Peruviana, Con., (Am. Jour. Conch., ii, p. 105,) from Peru. 



184. — V.(Auca) Awcasiana .^ d'Orb., (Voy. Astr. Pal., 1847, pi. ii, figs. 9-10,) may be a 

 Callista, a great deal resembling our Indian C. fabulina, n. sp. D'Orbigny seemed to have taken 

 a peculiar fancy to the name Auca, and made in this and another instance great confusion with it. 

 He describes in "Pal. de I'Am. merid. (1842)," p. 122, a TV/yje^i-like shell as T. az/ca, supposed to 

 be a tertiary fossil from Patagonia; subsequently, in 1847, he names quite a different shell, V. auca, 

 in " Voy. de 1' Astrolabe," and at last he quotes (Prod, ii, p. 237,) V. Aucasiana, adding the reference 

 of the tertiary V. Auca in the Pal. Am. merid. No version of this confusion appears satisfactory. 

 The most likely thing is, that d'Orbiguy, wishing in the Prodrome to correct the cretaceous species 

 V. Auca of 1847, the name having been applied for a different species in 1842, quoted by mistake 

 with it the reference of the latter instead of the former. This explanation would be strengthened 

 - by the fact that the name V, Aucasiana does not appear to have been published before, and is first 

 used in the Prodrome. 



185.— r. CAia, d'Orb., (Pal. Am. merid., 1812, p. 82,) may be a Caryatis.
