JVo. 16. — Bermudan Echinoderms. A Report on Observations 
and Collections made in 1899. 
By Hubert Lyman Clark. 
The following notes on the echinoderms of Bermuda are based 
on the collections made by the New York University party in June 
and July, 1899, and on personal observations made in April of the 
same year during a two weeks’ visit to the islands. I wish to ex¬ 
press my great obligation to Mr. F. W. Carpenter for the care with 
which the specimens were prepared, and for his valuable field notes, 
which add so much to the interest of the collection. The University 
party was stationed during this, its third visit to Bermuda, on 
White’s Island, in Hamilton Harbor, between the city and the Paget 
shore. My own observations were made at Bailey’s Bay, on the 
north shore, where the University parties of 1897 and 1898 had 
been located. 
No new star-fishes, brittle-stars, nor sea-urchins were added to 
the list during the past summer, but several specimens of the large 
star-fish, Luidia clathrata (Say) were collected on the beach at 
White’s Island. The only previously recorded specimen was taken 
in Harrington Sound in 1898, and was said to have been “ salmon- 
pink ” in color when alive. The specimens taken this year are all 
bluish gray above and cream color beneath, the normal color of this 
species. It would be interesting to know whether the Luidias in 
Harrington Sound are always differently colored from those in 
Hamilton Harbor. My observations on the more common star-fish, 
Asterias tenuispina , seem to show that in that species the speci¬ 
mens from the Sound differ from those collected on the north shore. 
The number of arms was noted in all the individuals seen, and as 
these were all collected in two places some distance apart, the result 
is interesting. One of these places was on the north shore at Coney 
Island, near the bridge, and here eleven specimens were found. Of 
these, six had six arms, three had five, and two had seven. The 
other locality where Asterias was collected was on the northwest 
shore of Harrington Sound. Of twenty-nine individuals collected 
here, fourteen had seven arms, six had eight, three had six, three 
had five, two had nine, and one had apparently only four. In all
