270 GASTEROPODA OF THE INFERIOR OOLITE. 
204, ? Husprra species. Plate XXI, fig. 2. 
Cf. Euspira coronata, Morris and Lycett, ‘ Great Ool. 
Moll.,’ part 1, page 46, plate vi, fig. 9. 
Bibliography, §c.—The authors admit that Huspira coronata may be regarded 
as an aberrant form of Huspira in which the carina becomes nodulous. But in 
reality there is no median carina on the body-whorl of any of the species described 
by those authors from the Great Oolite or the Inferior Oolite, such as H. canali- 
culata, EH. Sharpei, E. pyramidata, or EB. subcanaliculata. Moreover these species 
show hardly any trace of umbilicus, whereas ‘‘ Huspira”’ coronata is largely 
umbilicated. Thus “ Huspira’’ coronata can scarcely be classified with the other 
Euspire of Morris and Lycett, which are in facts Naticas, or, as our French 
contemporaries would say, Ampullinas. The type, which may be seen at the 
Jermyn Street Museum, is in excellent preservation, and appears to be unique, 
Its authenticity as a Great Oolite specimen seems beyond question. 
The above remarks are made in consequence of the discovery in Mr. Crick’s 
Collection of a fossil from the Northampton Sand of which the following is a 
Description : 
Spiral angle 5 : 2 0% 
Height of body-whorl to entire Rell : -. 60:2 100: 
Length : ; a) cash canine 
Shell globosely conical, turr eal ee nieaet: apex sharp. The whorls of the 
spire (four or five) are angulated, flat or slightly concave, arranged in steps or 
ledges, and ornamented with a nodulous carina which forms the angle of each 
whorl ; sutures close. 
The body-whorl, which occupies between six and seven-tenths of the total 
height of the shell, is largely expanded and flattened posteriorly ; it is ornamented 
by two conspicuous and nodulous keels, the upper one at the angle of the whorl, 
the lower one about haifway between the suture and the extremity of the rounded 
base ; between the keels the whorl is constricted. Aperture wide and semilunar, 
the outer lip slightly angulated; a considerable umbilical cavity is exposed, but 
this portion of the specimen is much corroded. 
Relations, §c.—Differs from “ Huspira”’ coronata in having a relatively longer 
spire, but chiefly in the different position of the anterior keel, which changes the 
form of the shell materially. I would distinguish it for the present as “ Huspira” 
subcoronata. Occurs in the Northampton Sand, Old Duston.
