by which to identity the species, and this, at liest, can be but 

 an unsatisfactory identification. In a few cases, in the speci- 

 mens collected, the septal sutures are shown, allowing a 

 more precise determination. The most abundant and 

 characteristic species of Gonintites in these concretions are 

 Goniatites intiunescens ( Beyr. ) and G. lutheri ( Clarke ). The 

 non-U mbilicated species are rare, a single doubtful specimen 

 having been noted. Besides the Goniatites a few other 

 fOvSsils occur in this rock. Those found are: 



Coleolus acicuhun ( Hall ). 

 Stvliolina fissa reiki (Hall). 

 Carcliola retrostriata (von Buch). 

 Lingula spatula t a (Yanux.). 

 Chonetes lepicla (Hall). 



Carcliola retrostriata (von Buch) is the only other com- 

 mon fossil, and although most of the specimens are small, 

 they show all the characteristic features. Lingula spatulata 

 (Vanux. ) is represented bv small s]xrimens only. This and 

 the other species are rare. 



In the shale below the Goniatite bearing layer, fossils are 

 rare. Occasionally in the immediate neighborhood of the 

 layer, Goniatites occur, but these are usually so poorly pre- 

 served that specific determination is out of the question. 

 Cardiola retrostriata (yon Buch) also occui's, though much 

 less commoidv than in the concretionary layer. Lunu- 

 licarcliuni fragile (Hall) is sparingly represented, and with it 

 occurs usually the minute pteropod Stvliolina lissurella 

 (Hall). Coleolus aeiculum (Hall) is another sparingly rep- 

 resented species, and a few Orthoceratites occasionally 

 occur. One well-preserved spccitncn of Orthoceras allied to 

 (). niephisto (Clarke) was found. 



On the ^yhole, the fauna of these beds is a very meagre one, 

 and were it not for the Goniatites, which are fretjuently 

 found, lying at the foot of the cliff, it might be entirely 

 overlooked.
