OF SOUTHERN INDIA. 75 



Ilomoini/a) ;~Ph. saitcta-crucis, P. and Camp., (OWL. ?) ;—Th. valaiigiensis, P. and C. ; Ph. icavensu, 

 and P/i. Cridoliana, Math., probably belong to Poromya ;^Ph. Parefi, Math., Ph. sinuo3a,M&th., 

 and Ph. obJiqnn, (P^/«o;jrt;ffl apud d'Orl).), have very much the appearance oi Pleuromyce, and the 

 last two species are likely to be the same. 



The cretaceous species described by Agassiz as Mi/opsis ( = Plenromyd) will be noticed under 

 Panopaa. I may only remark that tiiese appear to be true cretaceous Pleuromya, distinct from 

 Homomya or Panopaa. 



%\-\^1.— Goniomya caudata, Ag., [Ph. Agasshii, d'Orb.), Gon. Fillersensis, P. and C, Go,i. 

 liouyana, d'Orb., are noted as Pholudomya by Pic tot and Campiche. 



103-lOG.— P/^ Martini, Forb., (multic.) ;—Ph. pederuaUs, Riim., {OVUL.) ;—Ph. Cornnelianu , 

 d'Orb., (very much like Ph. aquivakis, Goldf., sp., MULTic.) ;—Gonioiiiya Arckiaci, Pict. and 

 Renev., {Ph. fhracioides, Pictet and Camj).). 



107-111.— PA. Geuevensis, Pict. and Roux., (triaxg.) ;—Ph. Fahriua, d'Orb., and Ph. Tri- 

 boleti, Pict. and Cami^. (MULTIC.) j—Gouiomyo (PhohuL), RaiiUnhma, d'Orb.; Ph. Dutempleana, 

 d'Orb., (CARDISS. ?). 



112-116.— P/i. Ligerierisis, d'Orb., (probably a Poromya) ; — Ph. cordiformU, Desh., (not Ph. 

 carAiformis, as stated by Pictet and Campiche), is likely a Pleuromya; — Ph. subdinensis, d'Orb., 

 (MULTIC.);— Goniom. MaiUeana (Pholad. id., d'Orlx) ; Ph. (Paehymya^? Myadtes) gigas, Sow. 



117-128.— P//. Archiaciaiia, d'Orb., (multic.) ■.—Goniomya, (Pholad.) Noueliana, d.'Orb. ; Ph. 

 Esmarki, Nills., sp., (Zeitsch. Deutsh. Geol., Gesell., xv, p. 145), CARDlss. ;—Ph. noduli/era, 

 Munst.,*( = P/^ albina, Rom.), Phol. eliptica, Munst. [ = ? Ph. Boyana, d'Orb., (mULTIG.J;— 

 PL decussala, Mant., sp. (see Zeitsch. Deutsh. Geol. Gesellsch., 1863, xv, p. 143), Ph. Marrotiana, 

 d'Orh., Ph. 3IoHlinsii, d'Orb., (caRDIss.) ;—Ph. rosfrata,-\ IMath., (multic.) ;—Ph. vmlonaia, 

 Rom., and Ph. Kasimiri, (Kazimiri), Vusch., (cARDlss.) ;— Ph. cequivaltis, Gold.?., (MULTIC, see 

 p. 79); — Goniomya designala, Miinst. = G. Geinitzii, d'Orb. 



Schafhseutl names a Phol. ligaHica, occurring in lignitic sandstone near Miesbach, which is 

 probably tertiary, though he does not say so. The same author quotes Ph. EsinarJci from the Gosaii 

 beds on the Kressenberg, (Sud-Bayern's Leth. Geog., p. 176). Giimbel (Bayer. Alpen.) quotes the 

 same from Siegsdorf. 



129-134— P/«. lmpanica,P. recurreiis, and Ph. CoUombi ( multic.);— Ph. spharoidalis ; Panopma 

 (on the plates Pholadomya) falUuv and apfiensi.s, (both of which are probably Poromya, and the last 

 may also be a P/eKro;«_j'ff^, see Coquand, liltage Aptien de I'Espagne, 1865, p. 92, &c. The same 

 author quotes Pk. Cornueliana, Ph. pedernalis, 'and Ph. gigantea, Sow., which last name has pre- 

 ference before that of Miinster's Ph. elongala. 



135-137. — Ph. obUqnissima, eordaia, and Steicarti are described from Ireland by Tate (Quar. 

 Jour. Geol. Soc, Lond., xxi, 1865, p. 40, &c.). 



IS8.— Ph. granulosa, Zittel (Denksch. Akad., Wien, xxiv, pt. ii, p. 116) (multic). 



139-152.— Eichwald (Leth. Ross., livr. xi, 1867, p. 748, &c.), quotes the following species 

 from cretaceous rocks of Russia, but his Neocomien is in part probably a Jurassic deposit : Ph. scalu 

 (= Ph. decorata apud Rouillier), Ph. inccqualis {= Ph. I Herat a, HTpudTrautschold), Ph. iti(eqi(icos(a, 

 are multic ; — Ph. Uralensis, d'Orb., resembles an inflated Thracia ;-'Ph. monticola, (cARDlss.); — 



* Pictet and Campiclie consider Ph. nodi/era and eUipfica of Miinster as identical, which is, I think, a mistake. 

 With the first Romer's albina, with the second d'Orbigny's Royana, have probably to be identified ; the form oi 

 both iigree, but the direction of the ribs is somewhat different ; I do not think that the granulations on the ribs are 

 of any particular importance. 



t Zittel (Denksch. Akad., "Wien, 1865, xxiv, pt. ii, p. 115,) identifies with this species one from the Gosau, and 

 besides describes a variety which he calls Ph. rustrata, var. Royana, d'Orb. If that peculiar form is to be considered 

 as a special variety, the name Ph. rost. va,r. pragnans, Zittel, ought to be applied to it, for its form is by no means 

 that of d'Orbigny's Royana, (see also Eichwald in Leth. Ross., livr. xi, p. 762).
