while the shales in Flat creek at the south side of the Mohawk, belong- 

 ing to the upper third afford : C . p u t i 1 1 u s and Lasiograptus 

 bimucronatus mut. t i m i d u s . 



The most peculiar distribution of all of these forms has Corynoides 

 c u r t u s which is common in the outcrops of the Appalachian trough [see 

 postea], but in the Mohawk valley has been traced only a short distance west- 

 ward (to Amsterdam) and has never been seen by the writer in collections 

 of the Utica shale of the middle and upper Mohawk valley, the outcrops 

 west of the Adirondack region or of the Cincinnati and Maquoketa shales. 



The faunule of Holland Patent, which has become known by Walcott's 

 investigation [1879] nas again a different aspect. It consists of : 



1 Callograptus compactus (Walcott) 8 Glossograptus quadrimucronatus ( Hall) 



2 Mastigograptus tenuiramosus (Walcott) 9 G. ? eucharis (Hall) 



3 M. simplex (Walcott) 10 Climacograptus typicalis Hall 



4 Leptograptus annectans (Walcott) 11 C. putillus (Hall) 



5 Pleurograptus linearis (Carruihers) 12 Lasiograptus bimucronatus mut. timi- 



6 Dicranograptus nicholsoni Hopkinson dus nov. 



7 Diplograptus foliaceus mut. vespertinus 



nov. 



Nos. 1, 3 and 5 of this list have thus far not been recorded from any 

 other locality in the United States ; the two species of Mastigograptus are 

 also known from Canada ; and Pleurograptus linearis, which 

 is known to me only in a single specimen from Holland Patent, marks a 

 zone in the Hartfell shales of Scotland and Scania. It is probably proper 

 to consider this faunule as typically representing the European zone of 

 Pleurograptus linearis \scc postca~\. 



The Utica shale faunules of the Appalachian trough in New York form 

 a group by themselves 1 by the common occurrence of Corynoides 



•They have been fully cited with their associated nongraptolitic forms by the writer 

 in N. Y State Mus. Bui. 42, 1901, p.519 ff.
