BERMUDA ECHINODERMS. 413 



i8. Brissus unicolor Kl. Reported from Bermuda by 

 Agassiz. 



HOLOTHURIANS. 



19. Cucumaria punctata Ludw. Two specimens collected 

 by the Ne\\' York University party. 



20. Cucumaria (Semperia) bermudiensis Heilp. A very 

 doubtful species described from a single specimen taken by the 

 Philadelphia party. 



21. Holothuria floridana Pourt. Five specimens collected 

 by the Philadelphia party. 



22. Holothuria captiva Ludw. Two specimens collected 

 by the Philadelphia party. 



23. Holothuria abbreviata Heilp. A very doubtful species 

 described from a single specimen, probably an abnormal indi- 

 vidual of the preceding species, collected by the Philadelphia 

 party. 



24. Holothuria surinamensis (?) Ludw. Six specimens, 

 collected by the New York University party, are referred to 

 this species with much hesitation. 



25. Stichopus diaboli Heilp. Reported as very common. 



26. Stichopus mobii Semper. = S. xanthomela Heilp. 

 Reported as quite common. 



27. Stichopus haytiensis Semper. Reported from Ber- 

 muda by Dr. Theel from a single specimen collected by the 

 "■ Challenger." I am inclined to think it may be the same 

 species as the preceding. 



28. Synapta vivipara Oerst. Recorded from Bermuda by 

 Dr. Theel in the '' Challenger" report under the name ^S. picta. 

 Dr. Theel also has numerous other specimens from the Ber- 

 mudas. 



Of the above twenty-eight species, four or five of the holo- 

 thurians are in doubt, so that the need of larger and more com- 

 plete collections is very obvious. Of the remaining twenty-two 

 or three species, all but one or two are distinctly West Indian, 

 so that it is only fair to expect the discovery of many more, by 

 more careful and systematic collecting.
