at the close of the second fauna,* which would place it a little 
below that of the Medina sandstone. 
The specific name of the species under consideration was 
given in honor of Rey. Wm. N. Cleveland, who obtained the 
specimens described in the Utica slate formation north of the 
village of Holland Patent, Oneida County, N. Y. On the same 
pieces of slate with them occur two characteristic fossils of the 
formation, Leptobolus insignis and Triarthrus Becki, and I have 
also obtained from the same locality and stratum of slate, 
Dendrograptus tenuiramosus, Chimacograptus bicornis, Srane 
Several collectors have been and are now working in the 
Utica slate both in New York State and Canada, and a number 
of undescribed and interesting species are in their hands, as 
also several described from the Trenton limestone but unknown 
from the slate before. It is largely due to the persistent efforts 
H 
County, N. Y., have been discovered, and their rich fauna 
made known from the slate, from one of which localities the 
form we have described was obtained.

In the following list there are included 48 species. Of these, 
22 have not, hitherto, occurred elsewhere on our coast; 26 
have been found farther north, in the Gulf of Maine, or off the 
coast of Nova Scotia, and may be considered as arctic; at least 
22 are Kuropean, and of these 18 or more are northern Euro- 
pean; at least 14, and probably more, have been taken in deep 
water, in the Gulf of Mexico, or off Florida, by Pourtales and 
gassiz, but there is, as yet, no general ‘lists of their star- 
fishes and ophiurans; of the whole number, only six are, 80 
far as known, peculiar to this district, - probably this num- 
ber will soon be reduce any of the species have a very 
extensive range, on both sides of the Attinte and also a great 
range in depth, occurring in much deeper water than was foun 
at any of our stations. Species dredged only in less than 60 
fathoms are not included. 
In the list, the range of depth given applies only to this 
special region, as determined by the stations here inclu ded.
