 From deep water, Embleton Bay. — R. Emhleton, Esq. 

 A few fine specimens of this rare and much controverted spe- 

 cies, with ovicapsules, have been got by Mr. Embleton growing 

 round the base of Plumularia myynophyllum. They agree very 

 closely with the figure of Ellis and Solander, excepting that the 

 pinnas are a little longer. It may be a question for future con- 

 sideration whether the S. Mmrjareta of Hassall is not this species 

 with a proliferous growth of the ovicapsules, as it is difficult to 

 point out any other difference between them. Judging from 

 specimens I have seen, this abnormal growth of the capsules 

 would appear to take place occasionally in S. rosacea, and also, 

 according to Lieut. Thomas, in iS*. towi«mert. (See Brit. Zooph., 

 470.) This may explain the reason why S. Margareta has been 

 referred alternately to each of these species.

Johns. Brit. Zooph., 73, t. xi., f. 2, 5, 6. 

 On other zoophytes from deepish water; frequent.
