The groove on the left {i.e., wlien viewed clorsally), after completing its ventro- 
lateral course, regains a straight direction, parallel to the longitudinal line of 
the guard, but that on the right is very different. After performing its 
ventro-lateral curvature on a level with the left, it again curves and returns 
to the dorso-lateral surface. At the point of return, however, it comes in 
contact with a second almost longitudinally straight groove, having a course 
both above and below the point of contact, but, not extending either to the 
alveolar margin or the guard apex, it dies out both above and below. In the 
alveolar region the grooves. are very sharp and deep.

Ohs . — Under this name Mr. Gurich has described a peculiar Belemnite 
guard, hastate in form and more or less strangulated in the alveolar region. 
There are two rather short dorso-lateral furrows, disappearing immediately 
the guard swells out from the strangulated neck to form the club-shaped 
distal end. There are also two long ventro-lateral furrows, wider apart in 
the alveolar region than the dorso-lateral are. They at first curve inwards 
on to the ventral surface, then back again to the sides rather below the 
greatest transverse diameter of the guard, and are then lost on the lateral 
surfaces. 
The hastate- clav^ate form of this guard and the constricted dorsal 
surface in the alveolar region ally this Belemnite to B. Canhami, Tate, but 
this does not joossess ventro-lateral grooves. I have not seen examples of 
this form.
