Characters. — Shell having a surface-ornamentation of delicate, parallel, longitudinal 

 striae. Segments arranged as in the other Quinqueloculine Miliola. Colour white to 

 yellowish. Length, ^th to ^^th inch. 



The finely striated Miliolce included under this sub-varietal term may be found in 

 every condition, from that approaching the common smooth unornamented shell, in which 

 but a few short lines appear at the base of the penultimate chamber, as in Plate IV, fig. 2 

 (a condition represented to some extent in D'Orbigny's 'Modeles ' Nos. 18 and 97), to 

 that in which the whole of the surface is covered by delicate hair-like markings. 



Mr. Wood's collection contains but a few specimens from Sutton, and we have not 

 noticed the variety in the other Crag deposits. We have never seen examples having 

 precisely the characters of Q. Brongniartii from our own coast, though we have a fair 

 approach to it in some specimens of Q. bicornis, in which, though the marking is analogous, 

 the shape of the shell is sufficiently distinct to justify separation. We find it occasionally 

 in the Mediterranean, and in most shallow-water- dredgings from tropical seas. In the 

 Tertiary clays of the North of Italy, in the Miocene of the Vienna Basin, and in the 

 Eocene of the Paris Basin, it is also sparingly found.
