TEREBRATULA. 
Puate IX, 
Species 34. (Mus. Taylor.) 
THREBRATULA (Kraussta) Lamarcnrana. Ter. testd 
late orbiculari, flecuosd, fulvescente-albd, crassiusculi, 
radiatim corrugato-liratd, liris hie illie bifureatis, 
striis concentricis, sub lente minutissimée crenulatis, 
rostro lato, abbreviato, foramine peramplo, deltidio la- 
tissimé partito ; valvis ad marginem internam subin- 
crassatis et spinulosis ; apophyse bifurcata, septo ver- 
sus marginem continuo. 
Lamarcr’s Kravssta. Shell broadly orbicular, flexu- 
; ous, fulvous-white, rather thick, radiately wrinkle- 
ridged, ridges here and there bifurcated, very mi- 
nutely crenulated beneath the lines with concentric 
strie, beak broad, short, foramen very large, delti- 
dium very widely divided; valves thickened and spi- 
nulose at the imner margin; apophysis bifurcated, 
septum continuous towards the margin. 
Terebratella Lamarckiana, Davidson, Pro. Zool. Soc. 1852, 
p- 80. pl. 14. f. 22 and 238. 
Kraussia Lamarchkiana, Gray. 
Hab. Sydney and New Zealand. 
This is the little Zeredratula affixed in small clusters, 
along with 7. (Waldheimia) flavescens, to the stone repre- 
sented in Plate I. It is of a broadly ovate pouch-like 
form, flexuous in growth, and rather strongly radiately 
wrinkle-ridged. It has the bifurcated apophysis of 
Kraussia, but the septum continues beyond the point of 
bifurcation nearly to the margin, which is in both valves 
neatly spinulose. A pale tinge of yellow is all that there 
is perceptible of colour in the species. 
Species 35. (Fig. a, Mus. Cuming; Fig. 4, Mus. Taylor.) 
TEREBRATULA (Kravussia) DEsHAyEsiI. Ter. testé tri- 
gono-orbiculari, crassiusculd, radiatim lirata, flecuosa, 
depressione centrali ad marginem subprominente, ful- 
vescente, carmineo-roseo radiata, vostro latiusculo, ab- 
breviato, foramine amplo, deltidio latissimé partito ; 
apophyse bifurcatim lamellata. 
Drsuayes’ Kravssta. Shell triangularly orbicular, ra- 
ther thick, radiately ridged, flexuous, the central de- 
pression being rather prominent at the margin, yel- 
lowish, rayed with crimson-rose, beak rather broad, 
short, foramen large, deltidium very widely divided ; 
apophysis bifuroately lamellated. 
Terebratula Capensis, Adams and Reeve (not 7. Capensis, 
Gmelin), Moll. Voy. Samarang, p. 71. pl. 21. f. 4. 
Kraussia Deshayesii, Davidson. 
Hab. Cape of Good Hope (dredged from a depth of a 
hundred and twenty fathoms); Belcher. 
Very closely allied to the preceding species, but of a 
more triangular form, painted with deep crimson rays. 
The habitat Corea given by Mr. Davidson, on the authority 
of Mr. Cuming, is incorrect. Avaussia Deshayesit was 
dredged off the Cape of Good Hope in the same vessel in 
which Terebratulina abyssicola was collected at Corea, and 
the labels got confounded together. Kraussia is as ex- 
clusively a type of the south temperate zone, as Terebratu- 
lina is of the north temperate. 
Species 36. (Fig. a, Mus. Cuming; Fig. 6, Mus. Taylor.) 
TEREBRATULA (KRaussia) PisuM. Ter. testd laté ovatd, 
flexuosa, depressione centrali plus minus suleatd, ra- 
diatim tenuiliratd, fulvescente-albd, ferrugineo-roseo 
interdum pallidissimée tincté, rostro lato, abbreviato, 
foramine amplo, deltidio latissimé partito ; apophyse 
conspicue bifurcatim lamelluta. 
Tue pea Kravssta. Shell broadly ovate, flexuous, the 
central depression being more or less grooved, ra- 
diately finely ridged, yellowish-white, sometimes 
faintly tinged with rust-rose, beak broad, short, fora- 
men large, deltidium very widely divided; apophysis 
conspicuously bifureately lamellated. 
Perebratula pisum, Valenciennes apud Lam. Anim. sans 
vert. vol. vii. p. 330. 
Terebratula Natalensis, Krauss. 
Kraussia pisum, Davidson. 
Hab. South Africa. 
This little species, which M. Valenciennes named the 
pea, and likened to a cherry-stone, resembles Kraussia 
Lamarckiana, but it is constantly distinguished by the 
fineness of the radiating ridges, while it is of larger size. 
Species 37. (Fig. a, 6, Mus. Taylor; Fig.c, Mus, Cuming.) 
TEREBRATULA (KraussIa) RUBRA, Ter. testi suborbi- 
culari, radiatim costatd, costis vivide rubris, vostro 
amplo, tumido, brevissimo, foramine peramplo, deltidio 
latissimé partito ; valvis modicé convexis, dorsali medio 
January, 1861.
