9. Teuebratula DininiORpnA, SloUczka, PI. VII, Figs. 4—5. 
T. testa siih-tric/ona, cl eprcssiti scuta, pcripheria incrassate et xakle ohtusata, con- 
centrice rucjosa, racliatini minutissime striata ; vulva liccmali fere plana, in parte 
anteriori medio leviter inijyressa ; v. neurali convexiuscida, nmhone pjromimdo, paido 
incurvo, foramine patido truncato ; deltidio macjno, concavo, medio sxdnrd juncto ; 
Uderihus timhoncdibus suh-rotundcdis sen ohtusis, ancjidimi 80° — fomnanfihiis. 
This species belongs to the tj^ic of Ter. diphia and diphioides, &c., represented 
in the highest beds of the Jurassic and the lowest of the cretaceous deposits ; it 
differs, however, from those species by the presence of a fine radiating striation. The 
only other species, I know, of the same type is Ter. G uiscardiana , Sequenza, de- 
scribed and figm'cd by Davidson from the Italian tertiary beds (Geol. Magazine, 1870, 
VII, p. 370, pi. xviii, fig. 0). The Indian cretaceous species is more dilated than 
the last, and has the beak distinctly, though not very strongly, curved. 
Locedihj. — Moraviatoor, in a concretionary, dark brown, limestone. Only the 
two figured specimens have been examined. 
Formation . — Ootatoor group. 
TEPEBEATFLIXA, D'Orhigny, 1847. 
(Davidson, Classlf. Brachiopoda, Ac.). 
Shell usually longer than wide, punctate, radiately striated or ribbed, neural 
valve with the beak truncate and perforate at the end, straight or slightly curved, 
with the dcltidium small and divided, or rudimentary, and Avith the usual hinge- 
teeth as in other TiinEHRATULiDyE ; hoBnial valve smaller, often with a straight hinge 
margin, produced into an auricle on cither side, apophysaiy apparatus short, scarcely 
equal to one-third of the length of the shell, formed by two, anteriorly united 
arms, about the middle of the sides connected by two branches, which remain, 
however, for some time separate in the young shells. The Dqrc of the genus is 
the recent T.capid-serpentis (Linnh). Dali (Am. Jour. Couch., 1870, a’oI. au, p. lOG) 
enumerates seven recent species. There are several known from tertiary deposits, 
hut the maximum of dcA'clopment appears to fall in the cretaceous epoch. A 
nearly complete list of the species from tlic latter is giA'cn by Schloenhach in 
Dunker’s and II. v. Meyer’s Palccontographica, 186G, a'oI. XIII, pp. 274 — 275. 
Tlic oldest species arc knoAATi from jiuassic deposits, one or tAA'o from the Lias 
being doubtful.
