OP SOUTHERN INDIA. 375 



Myt. eduliformis* Rcemer, (Nordd. Kreide., 184.1, p. 66), and M. kevis, Defr., (Diet. sc. 

 nat., xxxii, p. 151,) are considered as doubtful ; neither of them has been figured; the former is 

 a Mi/iilus, about two inches long and one inch high, ia form allied to ili". e(/«/w; the latter may, 

 according to Pictet and Campiche, belong to Iitoceramus mytiloides. 



125-129. — Modiola typica, nitens,polygona, flagellifera, radiatida, annedans, and Myiilus Arria- 

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

 have already been mentioned under previous numbers. 



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



130-153. — Lith. prmloiiga,oblotiga and Arc// iaci oi d^Orb., Aubersonensis, Pict. aud C, amygda- 

 loides and aveUana, d'Orb. ohesa,-\ ornata and prestensis, Pict. and Camp., sub-iiderniedia , d'Orb. 

 traversensis , P. and C, rostrata, carentonensis, sub-orbicularis, rugosa, and aqualis of d'Orb., Coqiiandi 

 Guer., pynformis, d'Orb., Toitcasiaua, d'Orb., coutorta,X Duj. sp., intermedia, d'Orb., cretacea^ 

 and hijjpuritum. Coq., Agke, d'Orb. 



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

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



155-156.— i. efow^fl-to, Pusch, sp., 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, Eatmonim, Ryck., andi. modiolus fCardita modiolus, Nilsson,) 

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

 species has already (antea p. 194) been cited in the family Glossid.e according to Pictet and 

 Campiche, but Nilsson's original figure rather supports, I think, Ryckholt's generic determin- 

 ation, while the shell figured by Reuss under Nilsson's name could hardly represent the same 

 species, the beaks being shown far too prominent. 



161.— Z. Weberi, Miiller, Suppl. Petrsf. 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. affiuis ei Ripleyana, Gabb, (Meek in Smiths. Misc. Coll., No. 177,1864, 

 p. ] 0,) are from North America. 



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



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



167. — L. awstralis, Gabb, Proc. Am. Philos. Soc, 1864, p. 194. 



168. — Z. cretacea, Coq., Lynch's Exped., p. 224 (non idem Coquaud). 



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

 taceous rocks. 



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



1. Lithodomus (? Botula) tumibula, StoUczka, PI. XXIII, Pig. 16, and 



PI. XXXVIII, Pig. 13. 



Lith. testa elongate sub-quadrangulari, tumida ; postice oblique truncata ; umbo- 

 nibus anticis, latis, incurois ; lunula profunda ; supei'fioie strlis tenuibus incrementi, 

 sulcis nonnullis latioribus interseclis instrucla, depressmie latiuscula sub-medlana 



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

 Montevideo.
