whole. The occipital furrow is deep, and the occipital segment 

 bore a strong spine, of which only the basal portion is preserved. 



So far as the state of the Bolivian and South African specimens 

 allows comparison, the resemblance of this form to Ph. avbuteus is 

 practically complete. The glabella is perhaps more nearly parallel- 

 sided, and the first two pairs of glabellar furrows are somewhat less 

 distinct. 



Dalmanites gemellus, Clarke, is similar in some respects, but the 

 glabella is- not elongated, and the frontal lobe is short.

A fragmentary specimen enclosed in a nodule shows the basal 

 portion of the glabella, the free cheek, and part of the thorax. 

 Both glabella and free cheek agree, so far as they go, with Dr. Clarke's 

 figures.

A very fragmentary specimen, in dark shale, shows the axis and 

 part of the right lateral lobe of a tail, which is probably refer- 

 able to the genus Dalmanites. There is a general resemblance 

 to Dalmanites Maecurua, Clarke, and D. ClarJcei, Ulrich l ; but 

 only ten annulations are visible on the axis and on the lateral 

 lobe, and the worn condition of the specimen prevents any closer 

 comparison. 



Locality (o). Between Achicheri and Aten.
