On June 5th the whole day was spent in dredging and 
tow-netting from the ‘‘ Mallard” (under the charge of 
Captain Batchelor of the Salvage Association) to the West 
and South of Port Erin, at the following localities :— 
1. Three miles West of Fleswick, 20 fms., 6 hauls of 
the dredge; good varied ground, old shells, &&. Amongst 
the species obtained were :—Halisarca dwjardini, Suber- 
ites domuncula, Clathria seriata, Aplysilla (2) sulphurea 
(green), Sarcodictyon catenata, Sertularella  tenella,* 
Diphasia pinaster,* Cellaria fistulosa, Carinella linearis, 
Palmipes membranaceus, Porania pulvillus, Stichaster 
roseus, Balanus porcatus, Xantho rivulosa, Atelecyclus 
septemdentatus, Crania anomala, Pandora inequivalvis, 
Pecten striatus. 
2. Fourteen miles West of Dalby, 60 fms., 2 hauls of 
dredge; bottom sticky blue clay-mud+: here were found, 
Lagena hertwigiana,* Jaculella acuta, Hyperammina 
arborescens, Plumularia catharina, Brissus lyrifer, Pan- 
thalis erstedi,* (arepresentative of the rare family Accetide. 
This addition to our local fauna has only been once before 
taken in British Seas, by Dr. Gwyn Jeffreys, 35 miles off 
the Skerries, Shetland, depth 75 fms.—as recorded by 
Prof. M‘Intosh), thirty species of Polyzoa including Beama 
mirabilis, Cellaria fistulosa, C. sinuosa, and Stomatopora 
granulata.* 
3. Hight miles West of Fleswick, 33 fms., 3 hauls of 
dredge; here were, Sarcodictyon catenata, Aglaophena 
myriophyllum, Diphasia pinaster,* Hchinocyamus pusillus, 
* New to the district. 
+The presence of this clay-mud in this deep depression of the Irish Sea 
may possibly—if it can be regarded as a glacial deposit—be considered 
confirmatory of the theory of glaciation of this neighbourhood held by the 
Glacialists’ Association, according to which there was a great movement of 
ice through the North Channel, and downwards between Ireland and the Isle 
of Man to St. George’s Channel, and so out to sea.
