reference to Knorr, the figures there not agreeing with 

 either De Montfort's account or figure. A sufficient know- 

 ledge of the characters of this fossil is certainly not yet 

 known to warrant a genus being formed from it. 



Calirrhoe. This genus is formed for the reception of 

 a fossil which is, undoubtedly, only the camerated alveolus 

 of a belemnite ^ such as is seen in situ, PL vi. fig. 11, and 

 which is frequently seen bearing all the appearances attri- 

 buted to this fossil. 



Telebois is appropriated to a fossil, the nature of which 

 has been undoubtedly mistaken by De Montfort. It is, 

 obviously, part of a vertebral column of the turban encrinite, 

 as hereafter described, and as figured in Organic Remains, 

 Vol. iii. PL xv. fig. 8, and was, indeed, considered as such 

 by Mr. Walch. 



Cetocis. Mr. Walch considered this fossil as a belenmite ; 

 but it having a stellated opening at its pointed termination, 

 it is placed, by M. de Montfort, in this genus. 



Hibolithes is a genus formed to receive the fusiform 

 belenmite figured in Vol. iii. PL viii. fig. 13, of Organic Re- 

 mains. The form of this fossil, which possesses every cha- 

 racter of the belemnite, cannot be considered as more than a 

 specific difference. 



Porodragus is a genus formed, by this author, on a 

 belemnite, bearing the same form as the last described ; but 

 having a round horizontal mouth ; a central ciphon ; conic, 

 smooth partitions ; a groove on the outer surface ; and being 

 superficially pierced with numerous longitudinal pores. 

 The partitions, siphon, &c. of this fossil, are those which 

 are to be found in every species of belemnite ; but the pores, 

 existing on the surface, are difficult of explanation. If 

 formed by the animal belonging to the shell, as supposed by 

 M. de Montfort, we may have a right to conclude that the 

 belemnite was invested by the animal which formed it.
