FROM THE SECONDARY ROCKS OF BRITAIN. 7 
There are three specimens of this cone in the British Museum, from 
the collection of Dr. Mantell. One specimen has the scar of a large 
peduncle. In another the scales are preserved in relief, and show that 
they had a tumid pyramidal apex. 
From the Weal den, at Brook Point, 
3. C.tumidus. Cone oblong-acuminate; scales about as broad as 
long, the apex rising into a tumid pyramid. (Plate LVII. Fig. 6.) 
A single specimen of this distinct little cone, an inch and a quarter 
long by three-qunrters broad, without locality, is in the British Museum. 
It is probably from Brook Point. 
4. C. elegaits. Cone ovoid, truncate below ; scales nearly as deep 
as they are wide. (Plate LVII. Fig. 9.) 
There are two specimens of this cone in the British Museum, from 
the collection of Lady Hastings. They are two and a half inches long 
by one and a half broad. The base is not only truncate but somewhat 
indented, and there is the remains of a large peduncle, having a dia- 
meter of nearlv half an inch. 
From the Wealden, Brook Point. 
5. Q. Walkvri. Cone oblong; scales broader than deep. 
This cone is figured by Mr. J. F. Walker in the Annals and Mag. 
of Nat. Hist. ser. 3, vol. 18 (Plate XIII. Pig. 5), and described as a 
Cycndean cone (p. 384), two and a half inches long and two and three- 
quarters in circianfereiice. The specimen is evidently very much water- 
worn. Perhaps the specimen in the British Museum, from which the four 
scales (Plate LVII. Fig. 7) were drawn, belongs to this species 
From a phosphatic deposit in the Lower Greensand, at Sandy, Bed- 
fordshire, probably of Wealden age. 
6. Q.spharica. Cone spherical ; scales as deep as they are broad. 
(Plate LVII. Fig. 8.) 
This cone is very much compressed and imperfectly preserved, but is 
evidently different from the others. 
Prom the Oxford clay of Wiltshire. 
7. Q. primava. Cone ovate ; scales as broad as they are deep.—

The scales of this cone are six deep and six round. Each one is 
dilated at its extremity and gradually thins away towards the axis.
