62 IOWA STUDIES IN NATURAL HISTORY 
from a local collector ‘a small worn and rounded fossil which 
seemed to be the cup of a erinoid allied to Holopus.’ Prof. 
Moseley tells me that he thinks it was a recent specimen in the 
dry state; but since it has unfortunately been lost, I am unable 
to say anything as to its nature.’’

P. H. Carpenter says: ‘‘This was supposed by Mr. [Sir 
John] Murray to belong to Sir Rawson Rawson... .; but Sir 
Rawson Rawson does not recognize it as his, and I conclude, 
therefore, that it is the mutilated dry specimen which Prof. 
Agassiz informs me was sent by him to Sir Wyville with per- 
mission to cut it up for details.’’ | 
It cannot be the same as No. 2, as it is not distorted, and has 
seven arms remaining instead of only six.

The specimen described below, in the author’s collection now 
in the United States National Museum. It was obtained from 
a local dealer by the Messrs. Ward of Rochester, New York, 
from whom I purchased it about twelve years ago; it was said 
to have been picked up on the shore after a storm. 
A NEW SPECIMEN OF HOLOPUS RANGII 
The specimen is quite complete, having the normal number 
of arms, 4 in the bivium and 6 in the trivium. The color is a 
dull dark green. The height, measured from the base of at- 
tachment, is 35 mm.; diameter at zone of greatest width, 23 mm. 
It is believed that a few figures of this specimen reproduced 
from photographs will furnish a useful addition to our knowl- 
edge of this singular form. 
In view of the ample descriptions quoted in the preceding 
pages it seems unnecessary to describe the specimen in detail; 
but I would like to eall attention to the oral plates, which are 
extremely well preserved, Carpenter’s figure of them being as 
he said, ‘‘somewhat idealized.’’ Although they lie within a dark
