112 CHAS. W. HARGITT. 



Lovenella grandis. — This species was first described by 

 Nutting from material dredged in Newport Harbor in 190 1. So 

 far as I am aware it has not since been taken. Specimens of the 

 hydroid have since been obtained by the writer at Woods Holl. 

 The colonies were somewhat fragmentary, but still justified Nut- 

 ting' s designation of it as "a beautiful species," and one could 

 wish it were more abundant. 



Sertularia Versluysi. — For the first time this interesting hy- 

 droid has been found at Woods Holl during the present summer. 

 Its habitat on Sargassum renders it not unlikely that this is not 

 the first time the species has drifted into these waters, but failed 

 of recognition. Congdon has also taken it on drifting Sargassum 

 at Bermuda. A feature of the specimens taken by me, and not 

 mentioned by other observers, is the presence of stolon-like out- 

 growths from the tips of branches and stems. These are more 

 or less common on my specimens, and it seems somewhat strange 

 that they should not have been observed before. 



Rhegmatodes. — This beautiful medusa {R. tenuis A. Agassiz), 

 occurring at very irregular periods, and in a very erratic manner, 

 made its appearance during the first week of September, 1907, 

 in considerable numbers and in its characteristic manner. Dur- 

 ing the last week in August a very few small and immature 

 specimens were taken in the tow, and suddenly large numbers of 

 full-grown medusae appeared in Buzzards Bay adjacent to Woods 

 Holl, hundreds of which were obtained with dip nets. On the 

 following day not a single specimen could be found. The pres- 

 ence of wind and some rain may have been influential in some 

 measure in the sudden disappearance, but perhaps not entirely. 

 This is the first time the species has been seen in numbers since 

 the summer of 1900. 



Campanularia. — In assorting some specimens in the collec- 

 tions of the Fisheries laboratory a single valve of Modiolus was 

 found on which several specimens of a species of Campamdaria 

 were found which at first inspection seemed rather strange. A 

 closer examination showed them to belong to the species C. verti- 

 cillata (Linn.).
