OP SOUTHERN INDIA. 343 



85-87.—^. Aptiemis and Fittoni, V. and C, and Austeni, d'Orb., would appear to belong 

 to Tfigonoarca, 



SS.—A, eostellata, Sow., agrees in the character of the hinge with Grammatochn. Nyst 

 suggests that the species is identical with Sowerby's Cucullma carinata. 

 89.— J. Forbesij P. and C, is either a Cucull^ea or a Trigonoarca. 

 90. — A. gurgitis, P. and R., is apparently a true Area, 



91-94.--J. Hugardiana, d^Orb., Triholeti, P. and C, Favrina, P. and R., and ^^cd^r^/^^^M, 

 Cott._, are Barhatim. 



95.—^. carinata, Sow. This resembles an Jrc^^ in shape, but as the shell is unequivalve, it 

 more probably belongs to Grammatochn, or some of the sub-genera of Cucullcea. - 



96-102.— J. CampicUana, P. and E., Cottaldina, di^Oih., nana, IjQjm., suhnana,V. 2in^^., 

 Hehertiana, Cott., bipartita, P. and H., (non Upartita, Rom., 1836,) and valdeiids, P. and C, 

 appear to belong to Trigonoarca, 



103. — ^. glabra, Park., (fibrosa apud d'Orbigny), is a Cucull(Ba. 

 104. — ^. (?^^5«, P. and R., (non A. obesa. Sow., 1833), probably a Trigonoarca. 

 105. — ^. rotundata. Sow., (^=^. rotundita, Nyst; non Cncul. rotundata, Rom., 1836, et 

 1837=^. dulmanensis, Nyst), is a Barbatia, 



106. — ^. formosa. Sow., ^=^. ve^msta, Nyst), apparently a Trigonoarca. 

 107. — J^. elongata. Brown, (non 6^^^(?. elongata, Sow.), a Macrodon. 



108-109. — A. pJioladiformis and elongatula, Nyst, 1848 (=^ Sarthacensis, d^Orb., 1850 — 

 elegans, d^Orb., 1844, non eadem auctorum) belong to Area. 



110-111. — A. Galliennei and Vendinensis, d^Orb., are Barbatice, 

 112. — A. Albertina, d''Orb., apparently a Trigonoarca. 

 113. — A. Cenomanensis, d-'Orb. ; this would appear to be a true Cucullcea. 

 114. — A. Tailburgensis, d''Orb., is a Trigonoarca. 

 115. — 'A. inscripta, d''Arch., a Barbatia. 

 116. — A. subacuta. Sow., apparently an Anomalocardia. 



117. — A. echinata, d^Orb., is one of the forms intermediate between Barbatia and Area. 

 118.—^. Bubdinensis, d''Orb., strongly resembles in form Deshayes'' Cucullaria. 

 119. — A. serrata, d''Orb., a true Area, 



120-125. — A. Gtierangeri, Moutoniana, Mailleana, Marceana, Fassyana, and Ligeriensis of 

 d^Orbigny all belong to Trigonoarca. 



126. — A. Renauxiana, Math., is a true Area. 



127-128. — A. Raspailli, d^Orb., Bequieniana, Math., are Barbatice of the type of Conrad^s 

 Cucullcearca ; they have the general form and the posterior flattening of the hinge line of Barbatia, 

 and the teeth do not appear to me to be more elongated than in large specimens of the recent 

 Bar. velata j I believe, therefore, that there is not sufficient ground for the constitution of a distinct 

 sub-genus. 



129. — A. Biifrenoyi, Haime, a true Area. 



130-134. — A. semisulcata, Math., Notieliana, Beaumontii, Matlieroniana of d''Orbigny, Bu- 

 mortieri, Haime, belong to Trigonoarca, 



135. — A. affinis, Duj., very insufliciently figured; the species may belong to Area or Barbatia. 

 136-137. — A. nereis and expansa, Nyst, 1848, (alata. Math., 1842, subalata, d'Orb., 1850), 

 are probably Barbatice, 



138-147. — A. ArcJiiaciana and sagittata, d^Orb., Icevis, Marticensis, and Galloprovincialis of 

 Matheron, Santonensis, d''Orb., Orbignyana,"^ Math., Royana 2i^d, cret ace a, ^^Oxh., all appear to 

 belong to Trigonoarca. 



* Nyst suggests that this species is probably tertiary, but does not give the authority for this supposition.
