OP SOUTHEEN INDIA. 375 



Myt. eduliformis^ Eoemer, (Nordd. Kreide., 1841^ p. %^)i and M. Icevis, Defr._, (Diet. sc. 

 nat._, xxxii^ p. 151_,) are considered as doubtful ; neither of tliem lias been figured; the former is 

 a Mytllus, about two inches long and one inch high, in form allied to M, edulis ; the latter may, 

 according to Pictet and Campiche, belong to Inoceramus mytiloides. 



125-129. — Modiola typica, nit ens ^ poly gona, flagellifera, radiatnla, annectans, and Mytilus Arria-. 

 loorensis occur in our South Indian cretaceous deposits. Of these the first and fourth noted species 

 have already been mentioned under previous numbers. 



Lithodomus (see Pictet and Camp._, 1. cit., p. 524).

 and Mppuritum. Coq._, Agl^e, d''Orb. 



154. — L. spathulata, Gein., would rather seem to be an Icanotia, (a sub-genus of Baroda, see 

 antea, p. 145), than a LitJiodomus or Modiola. 



155-156. — L. elongatajVM^Q]i,^^.j and irregularis, Gein. The last named species does not 

 appear to be a Lithodomus, and the next one quoted by Pictet and Campiche must remain as 

 Modiola faba, Miill. 



157-160. — L, Ciplyana, similis, Hannonim, Ryck._, andX. modiolus (Car dita modiolus, Nilsson,) 

 are described by Ryckholt in his Mel. paleont., 1^^ part., 1852, pp. 127 et seq. The last named 

 species has already (an tea p. 194) been cited in the family Glossid^ according to Pictet and 

 Campiche, but Nilsson^s original figure rather supports, I think, Ryckholfs generic determin- 

 ation, while the shell figured by Reuss under Nilsson^s name could hardly rei^resent the same 

 species, the beaks being shown far too prominent. 



161.— Z. Weberi, Miiller, Suppl. Petrsef. Aachener Kreidef., 1859, p. 19. 



162. — L, alpina, Zittel, (Denksch. Akad., Wien, 1866, xxv, pt. ii, p. 87,) is from the Gosau- 

 formation. 



163-164. — L. affinis ^i Bipleyana, Gabb, (Meek in Smiths. Misc. Coll., No. 177,1864, 

 p. 10,) are from North America. 



165. — L. oviformis, Gabb, Pal. Calif., vol. i, p. 185. 



166. — L. socialis, d'Orb., Voy. d'Am. merid., 1842, p. 91.

168. — Z. cretacea, Coq., Lynches Exped., p. 224 (non idem Coquand). 



169-171. — Jjitkod, (Botula) tumidula, curta, and sub-cylindrica are from the South Indian cre- 

 taceous rocks. 



LITHODOMUS, Cuvier, 1817, (see p. 369). 



1. Lithodomus (? Botula) tumidula, Stoliczka, PL XXIII, Pig. 16, and 



PI. XXXVIII, Pig. 13. 



Lith, testa elongate sub-quadr angular i, tumida ; postice oblique truncata ; umbo- 

 nibus anticis, latis, incur vis ; lunula profunda; superficie striis tenuibus incrementi, 

 sulcis nonnullis latioribus intersectis instructa, depressione latiuscula sub-mediana 



* D'Orbigny describes (Voy. Am. Merid., 1842, p. 162,) a Myt. eduUformis from diluvial or quaternary beds at 

 Montevideo. 



t Non Lith. ohesa, Phil., a recent species.
