ful fossil figured on Plate 43, which was collected by Mr. F. W. Robbins 

 in 1893. Another is a well preserved example of an unusually small 

 variety of the species, collected by Dr. Beadnell, and presented to the 

 Harrogate Museum in England. Through the liberality of the authorities 

 and members of that institution, however, and with Dr. Beadnell's con- 

 sent, this interesting and in its way unique specimen has been permanently 

 transferred to the Survey collection. It is imperfect at both ends, and 

 measures not quite three inches and a half in its greatest length, by 

 about two inches in its maximum breadth. At the end the farthest 

 removed from the bend, the distance between the two limbs is not more 

 than five millimetres. On the prolonged limb the ribs are unusually fine 

 and numerous, bub on the anterior portion of the reflected limb, and 

 especially near the aperture, they rapidly become more distant and less 

 numerous. At the smaller end of the prolonged limb a small portion of 

 the septation is exposed, but no considerable portion of a continuous 

 sutural line can anywhere be traced. No other specimen that the wi'iter 

 has seen, shews any vestige of the septation.

The most perfect of these, the specimen figured, is at first coiled in an 

 irregular, loose, open spiral, but it rapidly straightens out afterwards 

 towards the aperture. It consists of rather more than one volution, which 

 is not coiled upon quite the same plane, its earliest portion being curved a 

 little to one side. In the specimen from the Trent River, however, the 

 straighter anterior portion is a little twisted laterally. The surface of 

 all the specimens is marked by thin, sharp and simple transverse ribs, 

 with concave grooves between them. In most of the specimens the ribs 

 are somewhat distant over the whole of the surface, but in the specimen 

 figured they are comparatively close together posteriorly. Septum un- 

 known.
