BERMUDA ECHINODERMS. 123 



in his description which will not apply to siinnanicnsis, while 

 his figures of the stools and his comment on their variabihty 

 apply perfectly to that species. Moreover, he neither mentions 

 nor figures the " rosettes," which are so very characteristic of, and 

 noticeable in floj'-idana and the holothurians of that group. The 

 diversity in the number of tentacles, the " distinctly papillate " 

 dorsal surface and the irregular distribution of the " elongated 

 yellowish pedicels," all point to stirinainensis. Finally it is 

 hardly probable that floridana should be common enough in 

 1888 for Professor Heilprin's party to collect five specimens, 

 while in 1897 and 1898 not a single individual could be found 

 by the New York University students. And since surinamensis 

 is obviously the common holothurian of the Bermudas, it is not 

 likely it would have entirely escaped the notice of the Philadel- 

 phia party. These reasons to me are sufficient for striking 

 floridana from the list of Bermudan holothurians. 



There are seven specimens of the holothurian which was 

 identified from two specimens in the collection last year,^ as 

 Ciiaimaria piuictata Ludvv. Several of these are beautifully 

 preserved, thanks to Mr. Carpenter's skill, and the tentacles and 

 pedicels are as well extended as in life. A careful study of 

 these specimens has confirmed their identity and led me to the 

 conclusion that Semperia bermiidensis Heilp. must be considered 

 a synonym of Cuaimaria punctata Ludw. The seven speci- 

 mens before me vary in size from 40 mm. by 15 to 70 mm. by 

 25. The tentacles are ten in number and are arranged either as 

 nine long and one short, or seven long and three short, or one 

 very long, three on each side medium and three short, or all ap- 

 proximately equal. The variation in the number of Polian 

 vesicles is also notable. Four specimens have one each, two 

 have two each and one has three. The stone-canal is single 

 and usually in the mesentary but sometimes the end is free. 

 The genital bundles have numerous (40—50) undivided fila- 

 ments, yellow or orange in color, and three or four centimeters 

 long. The vent is more or less rayed and one specimen seems 

 to have anal teeth but the presence or absence of the latter 

 seems to be only a question of the more or less calcifying of
