ANTICOSTI ISLAND FAUNAS. 
23 
NEW GENERA AND SPECIES OF FOSSILS FROM 
ANTICOSTI ISLAND. 
The postponement of publication of the complete faunas of 
the Anticosti Island section until the completion of further field 
work, is the excuse for the present appearance of the descrip- 
tions that are given on the pages which follow. Since one of 
the generic terms has already been referred to by Professor T. 
E. Savage 1 and there is a prospect that another will soon be 
used by another student, it has seemed desirable and wise that 
their definitions and those of a few others of the more important 
forms be given. Bibliographies will be omitted as fa f as possible, 
leaving this to the complete description of the faunas. 
Phylum, COELENTERATA. 
Class, Hydrozoa Huxley. 
Order, Graftolqidea Lapworth. 
Suborder, Axonofhora Frech. 
Genus, Climacograptus Hall. 
Climacograptus tyficalis var. magnificus n. var. 
A common form in the Macasty black shales is a giant 
variety of the C. typicalis group and to this the above varietal 
name has been applied. It has the same type of rhabdosome 
with the rapidly narrowing sicular end and the two sicular 
spines. The rhabdosome attains a width of at least 4 mm. and 
an unknown length, but at least 70 mm. There are eleven to 
fourteen thecae in 10 mm. It differs from C. typicalis in being 
longer and wider. 
Horizon and Locality. Ordovician; the specimens were 
collected at Macasty bay from a large block of the Macasty 
shale. The writer has collected similar specimens of almost 
the same size from the Utica black shales on the banks of the 
Rideau river at Ottawa, Canada. 
The holotype is in Peabody Museum, Yale University. 
Class, Actinozoa. 
Order, Madre for aria M ilne-Edw ards .
