In Ms magnificent work, (Die Bracliiopoden, 1871,” page 112, 
plate 39, figure 46-—59 ;) many varieties of Terebratula spinosa 
are well figured, viz.: from Braun, Jura, e, there is var. inflata , var. 
setosa,v(iY. myriacantha,Tj.T)esloYLg. (Bull.Soc. Normandie,1858,) 
var. costata d’Orbigny, (Prodrome, Yol i., page 286) ; and from 
the Bradford Clay of Biedlingen, Terebratula spinosa sinuata. 
The variety, T. spinosa var myriacantha , E. Desl. appears to 
approach nearest to the so-called Rhynchonella senticosa of the 
Inferior Oolite of England, hut is much coarser ribbed. 
Quenstedt says “ Noch besser wiirde der Yarietatenname 
spinulosa dafiir passen.” He also says “ Spinosa setosa , (figure 
56), aus dem mittlern braunen Jura von Aalen, voll mittelfeiner 
Bippen, hat Buch mit senticosa SchlctheinTs verwechselt.” 
All his varieties of Terebratula senticosa come from the Weiss 
Jura (Middle Oolite), viz. :— T. senticosa impresses T. senticosa 
alba , T. senticosa silicea. 
Oppel (Die Juraformation, 1856,) page 432, gives Rhynchonella 
spinosa , Schlotheim as occurring in the “ Unter Oolith ” 
(Bajocien, Inferior Oolite). He is doubtful whether Terebratula 
senticosa Schlot, and Terebratula senticosa von Buch, belong to 
this species. He considers Zieten’s figure 1, plate 44, Wurtemb. 
Yerst.,to belong to the true Rhynchonella spinosa, 1832, but von 
Buch refers this figure to Terebratula senticosa (Soc. Geol. 
France, Tome 3, page 162). 
Oppel, also, at page 608, states as occurring in the Oxford 
gruppe “ Rhynchonella spinulosa , N. sp.— Hcmithiris senticosa , 
d’Orb., 1850, Prodr. 13, 456 (Schloth. ?), non Davidson.” 
Braun (Mittlerer Jura), 1869, page 289, gives several 
localities in North Greimany for Rhynchonella spinosa. 
Davidson describes and figures Rhynchonella spinosa , and 
the so-called Rhynchonella senticosa, in his paper on the 
Brachiopoda of the Inferior Oolite of Bradford Abbas and 
its vicinity.—Proc. Dorset Club, Yol. i, 1878. He also 
gives some remarks about these species in his Suppl. Ool., Brack. 
Pal. Soc., 1878. 
Szajocha “Die Bracliiopoden Fauna der Oolithe von Balin 
bei Krakau, 1879,” gives an account of Rhynchonella spinosa, 
and says it is found at Balin in a good condition, and tolerably 
plentiful. He gives two gpod figures, Plate v., figures 17—18.
