This species is characterized by the combination of a relatively 

 long glabella, rather narrow strongly convex free cheeks, somewhat 

 rounded anterior outline, pustulose surface, and strong, sharply de- 

 flected anterior spines. The glabella is strongly convex along its 

 middle with distinctly flattened lateral slopes, truncated conical, the 

 maximum length and width about equal. The posterior lobes are 

 outlined by a small inwardly diminishing ridge instead of a furrow. 

 Unfortunately both specimens on which the species is founded lack 

 the posterior edge of the occipital ring, so it is impossible to say 

 anythmg concerning the character of the occipital spine that prob- 

 ably occurs on more perfect specimens. 



Compared with other American species of the genus, T. gelasinosus 

 is at once distinguished by its relatively longer glabella. It is ap- 

 proached in this respect, also in the size, outline and contour of 

 the fixed cheeks, by T. granulatus Angelin but differs conspicuously 

 in the shape of the glabella, which is distinctly conical instead of 

 subquadrate. It lacks also the two horns on the anterior slope of 

 the glabella that set T. granulatus and T. hicornis apart from all 

 the other species of the genus. The present species reminds also of 

 T. latus but has a longer and more convex glabella, more sharply 

 deflected anterior spines, and, particularly, narrower and more 

 strongly convex fixed cheeks. In the two remaining pustulose 

 species, namely, T. pu^tulatus and T. fractus Barrande, the glabella 

 is much shorter and semiovate rather than conical. 



Occurrence. — From a subgranular limestone containing T. hi- 

 functatus in abundance, at Pratts Ferry, Ala. This bed of lime- 

 stone lies between the base of the graptolite-bearing Athens shale 

 and the top of the Lenoir limestone, hence its position corroborates 

 the evidence of its fossils on which mainly it is correlated with the 

 Whitesburg limestone of Tennessee and Virginia. 



TELEPHUS LATUS, new species 



Plate 3, Figures 13, 14 



This species is based on two cranidia. These agree in size with 

 T. fractus, the Bohemian genotype, but are considerably larger
