lyre or fiddle-shaped impression on the dorsal surface, was 

 dredged in mud in 25 fathoms outside Strangford Bar in 

 1857' by Dr. Dickie.^ 



Holothurioidea. — Several representatives of this class 

 have been found on our shores. Synapta inhcerens was 

 recorded by Wyville Thomson as abundant in mud banks 

 on the shores of Belfast and Strangford Loughs, and has 

 been stated to occur in considerable numbers in sandbanks 

 off Holy wood; a specimen of .S". digitata was found near 

 Carrickfergus by Mr. Hyndman and Mr. Thompson. 

 Cucumaria pentacies, C. lactea, and Thyone fusus have been 

 obtained in Belfast and Strangford Loughs ; Cita/maria 

 Hyndmatii, Phyllophorus Dnimmondi., and Psolus phaiitapus 

 in Belfast Lough ; and a specimen of Cuaanaria hyalina is 

 stated by Dr. Dickie to have been obtained by Mr. Hyndman 

 and Mr. Thompson in 15 to 20 fathoms in Strangford Lough.

Hydrozoa. — A considerable number of Hydroid Zoo- 

 phytes have at various times been obtained on the coasts of 

 Antrim and Down, but most of the species, however, are 

 generally distributed round the shores of Great Britain and 

 Ireland. 



Specimens have been obtained at various parts of the N.E. 

 coast of Ireland by Dr. Drummond, Messrs. Hassall, Hynd- 

 man, Templeton, Thompson, and others ; several species 

 were dredged in the neighbourhood of Belfast LoUii,h, in 

 1856-58, by the Belfast Dredging Committee of the British 

 Association, and a list of Zoophytes received from the north 

 of Ireland is given by Prof. Wyville Thomson in the Brit. 

 Assoc. Rep., 1857. 



Among the less common forms may be mentioned — 

 Eudendrium rameurn; Tiibiilaria hiryfix; Ectopleura Dumor- 

 tieri, recorded from Belfast Lough by Wyville Thomson, 

 but the specimens are believed by Hincks to be referable 

 to some other species ; Obelia gelatinosa ; Campanularia
