List of cretaceous species. 



As there are lu this case no suggestions to be made regarding newer generic determinations 

 I shall simply quote the names of the cretaceous species of Tngonia according to Pictet and Cam- 

 piche (Pal. Suisse IV"^ ser., S"'^ particj p. SSi), and add those which are not included in the list 

 of those authors. With the exception of the scabra and claoellatce. groups which I have united with 

 the sca2iJtoidea, the groups remain the same, as noted by Pictet and Campiche.

 wald from cretaceous beds of Russia (Leth. geogu., livr. x, 1867, p. 001 et seq.). Besides these 

 the same author mentions T. nodosa, carinata, scabra, inornata, and caudata. 



53-54. — T. distans and Auressensis are described by Coquand from North Africa (Pal. Prov. 

 Const., pp. 202-203). 



55-57. — Tr. Ilerzogii, Hausm., concardii/ormis, Krauss, and ventricosa, Kr., are noted by 

 Krauss from the neighbourhood of Algoa Bay from supposed cretaceous rocks, (Mem. Leop. 

 Acad., xiv, pt. ii, p. 453 et seq.), and from the same locality is the next species 



58. — Remondia Bronnii, Kr. (ibid. p. 449). 



59-66. — T. Belafossei, Coq. and B., Ranetiana, d'Orb., Gibboniana, Lea, (^= Hondaana Lea 

 Pal. Calif., ii, p. 248), Tocaimana, Lea, ? Lojoyei, (!L'Qx\i., (^? longa, d'Orb., ex imrte Prod, ii, 

 p. 78, No. 289), siib-crenatida, d'Orb., abrupta and Eumboldtii of Buch are from South America. 



67-75. — T. plicato-costata, Gal., Mooreana, Gabb., (Pal. Calif., ii, p. 269), thoracica,M.ox:i.

 America (including Texas and Mexico). 



76-78. — Meekia sella, radiata and navis, Gabb, (Pal. Calif., i, pp. 179-180), are from California. 



79. — Remondia fur cata, Gabb, (iliid. p. 270) from Mexico. 



From Palestine Conrad described in the App. to the Off. Rep. of Lynch's Expedition several 

 species which he considers as Jurassic, but Fraas (Wiirt. Nat. Jahreshefte, xxiii, 1867, pp. 237-238) 

 questions the fact. Conrad's syriaca he considers as identical with sinuafa, Park.; the others 

 are alta and cuneiformis, based upon imperfect east specimens; the latter has great similarity to 



* I agree with Pictet tliat the identification mth the American species is doubtful. There are, indeed most 

 marked differences in the thickness of the shell, direction of the ribs on the sides and on the area, and in the size of 

 the ligamental fulcra as compared with T. gibbuniaiia, and in ahrupta the differences in the form and ornamentation 

 of the shell are stUl more apparent.

 of Trigonice are figured.
