374 CRETACEOUS PELECYPODA 



78. — 3f^t. spectahilis, Miill., (Suppl. Mon. Petrsef. Aachener Kreidef.^ 1859, p. 10, pi. 1, 

 fig. 10). The figured specimen is imperfect; the ornamentation of the shell would indicate a 

 Septifer. 



79-80. — Mytihis elegans and Modiola flabellum are described by Schafhseutl from the Bavarian 

 Alps as occurring with fossils of cretaceous age, (Siid-Bayern^s Leth. geognost., 1863, pp. 156 and 

 157), 



81-82. — Modiola angusta, Eoemer, (Yerst. des N.-D. Oolith., Naehtrag, 1839, p. 33), and 

 Mod. Queteletiana are quoted from Neocomien beds by Eyckholt, (Mel. paleont., 1®^ part., 1852, 

 p. 154). 



83-87. — Mytilus (? SeptiferJ Benedeniamis, Eyck., Myt. Tomacensis, d^Arch., Mod, mida, 

 Ryck., Mod. ( ? Septifer) Ciplyana and Moreniana, Eyckholt, (Mel. paleont., 1^^' part., 1852, 

 pp. 147, 150, 152, and 155). 



88-89. — Mod. MuUeri, Bosq., 1860 (=Myt. reversus, MiilL, non Sow., sed non Myt. Mulleri, 

 d'Orb., 1850 = ilf. gryphoides, MiilL; et non Myt. Mullen, Eyckh., Y'^'qI ^ Modiola f ah a, 

 Miiller), and Jiyz^. i>^^^j/^^^^^<9. Bosquet, (=Myt. lanceolatus, MiilL, non Sow., vide Staring^s 

 Bodem v. Nederland, 2^^® deel) . 



90. — Modiola f aha, "^ MiilL, (PetrsBf. Aachener Kreideform., pt. i, 1847, p. ^'o,=:.Myt. Millleri, 

 Eyckholt, Mel. paleont., 1^' part., 1852, p. 150). I have examined a small specimen of this 

 species transmitted to our Museum by Dr. Bosquet, and I think it to be a true Modiola, not a 

 Lithodomtis, 



91. — Myt. SartJiensis, Gueranger, (Album paleont. d. 1. Sarthe, 1867, pi. xxiii, fig. 1), appears 

 to be based upon a fragment of Modiola flag ellif era, Forbes. 



92-93. — Myt. Brueti and M. (?) Coloni(2, Gueranger, 1. cit., pi. xxiii, figs. 2 and 8. 



94-97. — Mod. Uralensis, d'Orb., vicinalis, d''Orb., cuneiformis, Eichw., and Fisclieriana 

 d^Orb., are besides a few others recorded by Eichwald from Neocomien beds of Eussia, (Leth. 

 ross., xme livr., 1867, pp. 531 et seq.). 



98. — Modiola indiff evens, Coq., is the only species known from Africa. 



99-106. — Modiola attemmta, M. and Hay den, concentrico-costellata, Eoem., cretacea Conr 

 Jidim, Lea, MeeJcii, Ev. and Shum., ovata, Gabb, pedernalis, Eoem., and Saffordi, Gabb, (Meek 

 Smith. Misc. Coll., No. 177, 1864, p. 11). 



107-109.— -J^^^i^^^.^ semiplicatus'\ , Eoem., stiharcitatus. Meek and Hayd., tenuitesta Eoem 

 (Meek, ibidem). 



110-112. — Crenella elegantula. Meek smd lisijd., granulato-cancellata, Eoem., and C. (8talaq~ 

 minm) sericea. Con., (Meek, ibidem). 



113-114. — Mytilus ? humerus, Con., and Stalagmium concentricum , Gabb, are g'iven by 

 Conrad from the so-called lower eocene, or rather cretaceous, rocks of California (Smith. Misc 

 Coll., No. 200, 1866, p. 5). They are both described by Gabb in the Palseontology of California 

 as coming from cretaceous deposits. 



115-117. — Myt. paupercultts, ascia et qttadratus, Gabb, Pal. Calif., vol. ii, p. 245. 



118-121. — Modiola Sishyonensis, ornata,% cylindrica et major, Gabb, ibid, pp. 245 and 

 246. 



l^^.—Septifer dicliotomus, Gabb, ibid., vol. i, p. 186. 



123-124. — M.od. Socorrina, d'Orb., (Coq. foss. de Colombie) and Myt, Araucanus d^Orb 

 (Voy. d^ Astrolabe, 8cc.) are from Chili.

% Should Myt. ornatus, Miinst., prove to be a Modiola, Gabb's name will have to be altered.
