List of ceetaceous species. 



As there are in this Gase no suggestions to be made regarding newer generic determinations, 

 I shall simply quote the names of the cretaceous species of Trigonia according to Pictet lind Cam- 

 piche (Pal. Suisse IV°^® ser.^ 3^« partie^ p. 384)^ and add those which are not included in the list 

 of those authors. With the exception of the scahrm and clavellatcB groups which I have united with 

 the 8cap]ioidea, the groups remain the same, as noted by Pictet and Campiche.

50-52. — T. intermedia, Pahrk., Jonioi, Rouill., and Falckii, Rouill., are described by Eich- 

 wald from cretaceous beds of Eussia (Leth. geogn., livr. x, 1867, p. 601 et seq.). Besides these 

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



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

 Const., pp. 202-203). 



55-57. — Tr. Herzogii, Hansm., concardiiformis, 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. — Bemondia Bronnii, Kr. (ibid. p. 449). 



59-66. — T. Belafossei, Coq. and B., Hanetiana, d^Orb., Gihhoniana, Lea, {=: Hondaana, Lea, 

 Pal. Calif., ii, p. 248), Tocaimana, Lea, ? Lojoyei, d'Orb., (^=^ ? longa, d'Orb., ex parte Prod, ii, 

 p. 78, No. 289), sul -crenatula, d'Orb., ahrupta and Ilumholdtii of Buch are from South America. 



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

 America (including Texas and Mexico) .

79. — Bemondia furcata, Gabb, (ibid. p. 270) from Mexico. 



Prom Palsestine 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 sinuata. Park.; the others 

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



* I agree with Pictet that the identification with tlie 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 hgamental fulcra as compared with T. gihhoniana, and in ahrupta the differences in the form and ornamentation 

 of the shell are still more apparent.

 of Trlgonice are figured.
