TEREBRATULA. 
Prate II. 
Species 1. (Pl. 1. Mus. Brit.; Pl. 2. Fig. 1 @, Mus. 
Metcalfe; Fig. 1 4, Mus. Taylor.) 
TEREBRATULA (WALDHEIMIA) FLAVESCENS. br. testd 
subtrigono-ovatd, tenuiculd, inflata, sordide flavescente- 
corned, semipellucidd, rostro obeso, nunc rectiusculo, 
plus minusve producto, nunc recurvo, foramine sub- 
amplo, deltidio integro, amplo ; valvis tripartito-flexuo- 
sis, medio levibus, deinde radiatim plicato-costatis, ad 
marginem acute undatis ; apophyse elongata, latius- 
culd, conspicue reflexa. 
THE YELLOWISH WaLDHEIMIA. Shell somewhat trian- 
gularly ovate, rather thin, inflated, dull yellowish- 
horny, semitransparent, beak stout, sometimes rather 
straight, and more or less produced, sometimes re- 
curved, foramen rather large, deltidium entire, large ; 
valves tripartitely flexuous, smooth in the middle, 
then radiately plicately ribbed, sharply zigzag at the 
edge; loop elongated, rather broad, conspicuously 
reflected back.

Terebratula australis, Quoy. 
Waldheimia australis, King. 
Terebratula recurva, Quoy. 
Hab. South Anstralia. 
This well-known species inhabits the shores of South 
Australia in great abundance. The fragment of rock, with 
lumerous specimens attached to it, represented in Plate I., 
was brought by Mr. Jukes from Port Jackson, Australia ; 
and MM. Quoy and Gaimard relate, in their account of 
the mollusca of the voyage of the ‘ Astrolabe,’ that at Port 
Western, Bass’ Straits, hundreds were brought up at each 
haul of the dredge, either grouped among themselves by 
their pedicles or attached to the debris of other shells. 
The small species mingled with this upon the stone in 
Plate L., is 7. Lamarckiana. 
Species 2. (Mus. Metcalfe.) 
TEREBRATULA (WALDHEIMIA) DILATATA. er. testd sub- 
orbiculari, sordidé fuscescente-albd, rostro lato, bre- 
viusculo, subtus utringue depresso, foramine amplo, 
deltidio lirato, partito ; valvis yibbosiusculis, levibus ; 
apophyse valde producta, elongato-reflexd. 
THE DILATED WaLDHEIMIA. Shell nearly orbicular, 
| THE GLOBOSE WALDHEIMIA. 
dull brownish-white, beak broad, rather short, de- 
pressed beneath on either side, foramen large, delti- 
dium ridged, divided ; valves rather gibbous, smooth ; 
loop much produced, elongately reflected.

Terebratula Gaudichaudi, De Blainville. 
Hab. Straits of Magellan ? 
The only specimens known to me of this species are the 
one here figured, from the collection of Mr. Metcalfe, one 
of about the same dimensions in the British Museum, and 
one scarcely so large in the Museum of the Bristol Insti- 
tution. There are specimens of much larger size, Mr. 
Davidson informs me, in Paris, in the collections of the 
Jardin des Plantes and of M. Delessert. The habitat 
‘Straits of Magellan,’ given by Dr. Gray in the British 
Museum Catalogue, is hardly sufficiently well authenti- 
cated. 
Species 3. (Fig. a, c, Mus. Metcalfe ; 
Fig. 6, Mus. Taylor.) 
TEREBRATULA (WALDHEIMIA) GLOBOosA. Ter. 
ovato-globosd, olivaceo-corned, rostro producto, sub- 
testa 
acute incurvo, subtus utringue excavato-depresso, fora- 
mine parvo, interdum minuto, deltidio partito, radiatim 
sulcato, transversim concentrice rugato ; valvis levibus, 
obsolete malleatis, obscurissimé tripartitim flecuosis, 
lineis incrementi plerumque rudibus ; apophyse am- 
pliter producta et reflexd. 
Shell ovately globose, 
olive-horny, beak produced, rather sharply incurved, 
excavately depressed beneath on either side, foramen 
small, sometimes minute, deltidium divided, radiately 
grooved, transversely concentrically wrinkled ; valves 
smooth, obsoletely malleated, very obscurely tripar- 
titely flexuous, lines of growth rude; loop largely 
produced and reflected.

Terebratula Californica, Koch. 
Hab. California, Coquimbo. 
The only shell that has been assigned to Lamarck’s 
1. globosa is a single worn specimen of the well-known 
Californian species above described, in which the foramen 
is largely eroded and the deltidium forced open by age or 
November, 1860.
