dredged today by Mr. Hyndman oiF Castle Chichester, Belfast bay, 

 was brought to me. It was taken about a mile from the shore on 

 shelly ground in from six to ten fathoms water. Being soon after 

 capture sent to Dr. Johnston, it proved as new to him as to myself, 

 and was left at Berwick for him to notice until lately, when in con- 

 sequence of his having ceased to study the Annelides it was returned 

 to me. Professor Allman then kindly undertook its examination and 

 determined it to be this Euphrosina. The specimen is an inch in 

 length ; the size attributed to the species by M. -Edwards. Two 

 others diiFering only in being smaller were last year purchased by 

 Mr. R. Ball (of M'Calla), but it was not stated on what part of the 

 coast they were procured. This is the first record of the genus Eu- 

 phrosina inhabiting the British seas. M. -Edwards's specimens were 

 taken on oyster-banks in the two neighbouring localities of St. Malo 

 and between Granville and Chausey ; in the latter locality, a league 

 and a half from the shore, and at the depth of fifteen fathoms.

Specimens of this parasite were found attached to the gills of 

 whiting (Gadus Merlangus) in April ; to those of the hake {Gadus 

 Merlucius) in May ; and to those of the pollack {Gadus Pollachius) in 

 October 1837, by Dr. Bellingham of Dublin, in the market of which 

 city the fish were purchased. The specimens are mostly a^out 4 lines 

 in length. The genus has not before been noticed as found in the 

 British seas. 



Zoophytes. 



1. Gorgonia verrucosa, Linn., Johnst. Brit. Zooph. 



The first Gorgonia of any species which I have seen from the coast 

 of Ireland, was a portion of G, verrucosa sent to me in March last 

 by Mr. R. Ball. The specimen was procured at the island of Lam- 

 bay, off the Dublin coast, and taken to Mr. Warren by the man who 

 found it on account of the size (18 inches from base to extremity of 

 branches), he having never seen any so large before*. 



of Aud. and Edw. Along with the Euphrosina, a singular new species, of 

 which Dr. Johnston constituted the genus Spinther {S. oniscoides), was 

 taken ; it is included in the former family. 



* This has been erroneously called Gorgonia Jlahellum in the published 

 list of donations to the Dublin University Museum, Dec. 1848, p. 8. A 

 specimen of G. jlahellum with the root attached was brought up in a trawl- 

 net from eight to ten fathoms depth off Bangor, Belfast bay, last summer, 

 by Mr. Hyndman, who judiciously considered it a foreign specimen. That 

 it had for some time been a denizen of our seas was however evident from 

 the native productions whicli were attached, such as Crisia ehurnea, Cellu- 

 laria ciliata ; Granfia compressa and G. ciliata ; Serpula triquetra, with 

 small portions of ConfervcB and other native Algae. This Gorgonia was 14 

 inches in height and the same in breadth.
