six, while Professor Heilprin reports having found one or two 

 specimens with only five. The specimens I have agree in every 

 particular with the most careful descriptions of Astcrias toiui- 

 spi)ia Lamk., from the Mediterranean and eastern Atlantic, and, I 

 have no doubt, belong to that species. Verrill has separated 

 the Astcrias of Bermuda from A. tcnuispina as A. atlaiitica, on 

 the ground that the proportions of the arms are slightly differ- 

 ent and that there are no large single pedicellaria^. Sladen, in 

 his report on the starfishes of the "Challenger" collections, 

 identifies the only Astcrias from Bermuda as A. tcnuispiua and 

 questions the authenticity of Verrill's species. In the specimens 

 before me the proportions of the arms vary considerably and 

 large single pedicellarise occur in the ambulacral furrow as in A. 

 tenuispina. Accordingly it would appear that A. atlantica must 

 be regarded as a synonym of that species. In several of the New 

 York University specimens the prominent spines on the upper 

 surface are rather unusually colored, being strongly tinged with 

 violet. The other starfish, of which there are five specimens in 

 the collection, is Astcriiia folium Ltk., a small pentagonal 

 species found closely adhering to the under side of broken 

 pieces of rock. They are very light colored, almost white, but 

 one is strongly tinged with blue. They agree in all particulars 

 with specimens of the same species from Jamaica. 



The two Ophiurids are of no especial interest, though one of 

 them has not previously been taken in Bermuda. This is OpJiiura 

 appressa Say, of which there are three specimens in the collec- 

 tion. They were kindly identified for me and compared with 

 Jamaica specimens by my friend, Mr. Caswell Grave, of the Johns 

 Hopkins University. Of the other species, Op/iioncrcis reticu- 

 lata Ltk., there is a large number of specimens. It seems to 

 be the common brittle-star of the islands. 



The four Echinoids are all reasonably common in suitable 

 places, Professor Bristol tells me, and have all been recorded from 

 Bermuda before. They are Diadcnia sctusiiui Gray, Echiiuniictra 

 siibangularis Leske, Hipponoc csculcnta Leske and Toxopneustes 

 variegatus Lamk. Anyone familiar with the latter urchin as it ap- 

 pears in Jamaica or along our southern coast would never recog-
