NOTES ON BERMUDA ECHINODERMS. 

 Hubert Lvman Clark. 



(Read May g, i8q8.) 



The collection of echinodei"ms made in Bermuda in the sum- 

 mer of 1897 by the New York University party, has been very 

 kindly placed in my hands by Professor Bristol, for examina- 

 tion. Although the collection is in itself a small one, it is of no 

 little interest, as our present knowledge of the echinoderms of 

 Bermuda is very incomplete. So far as I can discover, no at- 

 tempt has hitherto been made to prepare a complete list of them, 

 so that it has seemed worth while to add to the .species in the 

 New York University collection, others which have previously 

 been recorded from the islands, thus making as far as possible a 

 catalogue of the littoral echinoderms of Bermuda. In 1888, 

 Professor Heilprin, of the Philadelphia Academy of Sciences, 

 published in the Proceeding's of that Academy, a list of the echin- 

 oderms, which he and a party of students had collected in Ber- 

 muda that summer. The list contains twenty species, six holo- 

 thurians, six echinoids, six ophiurids and two asteroids. Of the 

 six holothurians, four are described as new to science. The 

 New York University collection contains only eleven species, 

 but of these at least three are additions to Professor Heilprin's 

 list. The principal interest of the collection, however, lies in 

 the light which it throws on Professor Heilprin's " new " species 

 of holothurians, and on one of Professor Verrill's species of 

 starfish. 



There are only two species of Asteroids in the collection, but 

 both are of interest. One of them, of which ten specimens lie 

 before me, is the common starfish of the Bermudas. One of 

 its peculiar features is the great variation in the number of arms, 

 one specimen having nine, five having seven and the other four
