fragment, consisting of a septate, straight portion of 

 lgth, differs from the ' young form ' (fig. 4) of Jimbo 

 blique and fewer costae ; but a beautiful example from 

 Beds of Pondoland, belonging to the Geological 

 >wn, and kindly sent to the writer by Mr. Henry Woods, 

 /ell-preserved and two straight arms of 230-250 mm. 

 y comparable with Jimbo's type (fig. 3). 'Samites '

 row of ventral tubercles and the single costse are 

 Ixybeloceras crassum and 0. meekanum, Whitfield sp. 4 

 k, 5 and 0. liniatum, Gabb. 6 , but the fragment is too 

 of correct generic identification. 



•ybeloceras is here taken to include forms of ptychoceran 

 as hamitids and crioceracones, e.g. ' Ancyloceras ' 

 ihliiter. 7
