I. On January 29, 1893, the Committee had the use of 

 the Lancashire sea-fisheries steamer" John Fell." Several 

 hauls were taken about 7 miles to the west of Fleshwick 

 (Isle of Man), then some further to the south between 

 Port Erin and the Calf. Amongst other species obtained 

 were Cliona celata (fine, in various conditions), Sertularia 

 tenella, and a number of hydroids and polyzoa, Sarcodic- 

 tyon catenata, Porania pulvillus and Palmipes membra- 

 naceus, Astacilla gracilis, Inachus dorsettensis, Ascidia 

 venosa and A . virginea, Capulus hungaricus, Venus casina, 

 and Pectunculus glycimeris. 



II. On March 11-13 the work was again done from the 

 steamer "John Fell." On the 11th the steamer left 

 Douglas to examine the shoal lying to the north-east and 

 south of the Bahama light (see chart, Plate I.). Here, 

 along with various food-fishes and some commoner inverte- 

 brates, some very large specimens of Tritonia hombergi 

 were trawled ; also the ascidians Ascidia virginea, Didem- 

 num gelatinosum and Polycyclus savignyi (very large 

 specimens), Corystes cassivelaunus, Scaphander lignarius, 

 Aglaophenia tubulifera, A. myriophijllum, Galycella 

 fastigiata, and Eertularella gayi, which is a new record to 

 the district ; Eudendrium rameum, Thuiaria articidata, 

 Gonothyrcea gracilis and other zoophytes, and various 

 common polyzoa, some very abundaDt and luxuriant. 



On the 13th, after trying again the same shoal as on 

 the 11th, the steamer went to ' the top end of the Hole,' 

 26 miles east of St. Ann's Head, 30 fathoms. Here there 

 is sand to the north and mud to the south, and some hauls 

 were taken along the line of junction. Amongst other 

 things the following nudi branch s were obtained : Tritonia 

 hombergi, Dendronotus arborescens (up to 5 inches in 

 length), Eolis drummondi, Eolis rufibranchialis, and 

 Eolis far rani; also Virgularia mirabilis, and no less than
