194 NOTES AND MEMOEANDA. 



More specimens, however, are required to settle the relations of 

 these interesting forms. — F. W. Gamble. 



Saphenia mirabilis, Haeckel. — In the same haul of the large tow-net 

 in which the Phyllosoma elsewhere described were taken on the 

 night of July 16th I captured a large number, some hundreds, of 

 small Medusae of a single species. These proved on examination to 

 be the Goodsiria mirabilis of Strethill Wright, described and figured 

 by him in a paper in the Edinburgh Philosophical Journal, vol. Ixvii, 

 1859. The species has been placed by Haeckel (System der Me- 

 dusen, Jena, 1879) in Eschscholtz's genus Saphenia, of which two 

 other species only have been described. No other obseiwer than 

 Strethill Wright has recorded or described Saphena mirahilis, and 

 he took only three specimens near Queensferi'y in the Firth of Forth. 

 Strethill Wright's specimens were about an inch in diameter ; those 

 taken near the Eddystone were not so large, the largest being only 

 about 12 mm. The species, however, is certainly the same ; it is 

 distinguished by the depressed form of the umbrella, the presence 

 of only two extensile tentacles, and a very long and very extensile 

 peduncle several times as long as the breadth of the umbrella. The 

 genus Saphenia is placed by Haeckel in the family Eucopidse of the 

 order Leptomedusse. All the Leptomedusse whose development is 

 known are developed asexually from a fixed hydriform stock. The 

 development of Saphenia is at present entirely unknown, but it 

 seems probable that the numerous specimens taken near the Eddy- 

 stone were derived from some fixed hydroid which flourishes at the 

 bottom of the sea in that neighbourhood. — J. T. Cunningham. 



Pleurophyllidia Loveni, Bergh. — Another interesting capture made 

 last summer was that of the rare Opisthobranch Pleurophyllidia 

 Loveni, Bergh. A single specimen was taken in the shrimp trawl, 

 about two miles to the north of the Eddystone on the night of July 

 9th. It was accompanied by many Nudibranchs and a Pleuro- 

 branchus ; these Molluscs, as well as the Pleurophyllidia, were 

 identified by Mr. W. Garstang, and the list of them is as follows : 



Pleurohranchus inemhranaceus , 1 specimen ; Acanthodoris pilosa, 

 10 specimens, all white ; Philine aperta, 3 ; Scaphander lignarius, 1 ; 

 Eolis sp., several. 



The other contents of the trawl were a few small flat-fishes, a 

 number of Pecten opercularis, and a large quanty of Cellaria. 

 Only two specimens of PL Loveni are reocrded as taken in the 

 British area by Forbes and Hanley, and by Gwyn Jeffreys. But 

 Mr. Holt has recently recorded the capture of two specimens in St.
