rostro tumido-prominente, incurvo, foramine amplo, 
integro, deltidio amplo, rugato, indiviso ; valvis suba- 
qualibus, undique radiatim liratis, ad marginem sinu- 
atis ; apophyse elongata, dupliciter affixd. 
THE BLOOD-STAINED TEREBRATELLA. Shell somewhat 
triangularly globose, inflated, tripartitely flexuous, de- 
pressed in the middle, orange-red, deep at the lines of 
growth, beak tumidly prominent, incurved, foramen 
large, entire, deltidium large, wrinkled, undivided; | 
valves nearly equal, radiately ridged throughout, sinu- 
ated at the margin, locp elongated, doubly attached.

In this fine species there is little or no variation either 
of form or colour, and it may be at once distinguished 
from any other. Though unknown to Lamarck, and not 
till lately to Deshayes or Sowerby, it was described nearly 
half a century ago by Dillwyn, and admirably figured 
about the same time by Leach, in his ‘ Zoological Mis- 
cellany.’

Tue MaGet~an TEREBRATELLA. Shell somewhat trian- 
gularly ovate, rather depressed, tripartitely flexuous, 
broadly concavely impressed in the middle, yellowish- 
horny, sometimes tinged with rose, beak rather short, 
coneavely flattened beneath on each side, truncated, 
foramen large, incomplete, deltidium moderate, di- 
vided; valves more or less tripartitely radiately ridged, 
sinuated at the margin; loop elongated, reflected, 
doubly attached.

Three years before Gmelin gave the name of dnomia 
dorsata to this species, it was fully described and figured 
by Chemnitz with the name of Magellanica, which had 
already been given to it in French by Davila and Favart 
D’Herbigny. Mr. Broderip’s 7. Chilensis and Captain 
King’s 7. flewuosa and Sowerbyi are clearly varieties of it, 
the last being of a characteristic yellowish-red colour, 
which in very young specimens is a delicate rose-pink.

TEREBRATULA (TEREBRATELLA) TRANSVERSA. Ter. testa 
transverse ovata, flecuoso-contortd, medio concavo-im-

THE TRANSVERSE TEREBRATELLA. Shell transversely 
ovate, flexuously contorted, concavely impressed in 
the middle, dull yellowish-white, beak rather short, 
concavely flattened beneath on each side, truncated, 
foramen very large, deltidium small, widely divided; 
valves smooth, wrinkled with lines of growth towards 
the margin.

I doubt if this is anything more than a monster of very 
antiquated contorted growth of the preceding species. I 
have not seen the specimen to which Mr. Sowerby alludes 
in the collection of M. Janelle, but I find evident traces 
in Mr. Norris’s specimen, of the radiating ridges which 
are so characteristic in 7’. dorsata, and which in 7. trans- 
versa would appear, at first sight, to be wanting.
