of over 100 fathoms. In addition to surface gatherings, 
and the Irish Sea series, we have now before us 33 
successful vertical hauls in Scottish waters from depths 
of over 50 fathoms and 18 from over 100 fathoms. The 
deepest in the series are:—one of 133 fathoms between 
Croulin and Longa Islands in the Sound of Raasay, 
to the north of the great barrier formed by the large 
island of Skye, and one of 130 fathoms between Canna 
and Rum, to the South of Skye. The accompanying 
chart (fig. 5, p. 148), although on too small a scale to 
show details, will serve to give a general idea of the 
localities and of the distribution of land and water. It 
shows depths of over 50 fathoms shaded, and holes of 
over 100 fathoms are marked with a black outline. The 
twenty-five stations at which deep hauls were taken are 
marked by a small black circle enclosing a white cross. 
The localities may conveniently be grouped in three 
series: (1) those outside and north of Cantyre, (2) those 
further south in the Clyde sea-area, and (5) those in the 
Irish Sea. The Northern Scottish series number 41, the 
Southern Scottish series 26, and those from the Irish 
Sea from depths of over 50 fathoms are 66.* 
The hauls may be further classified as follows :— 
I.—The term ‘‘ Clyde Sea-Area’’ is used in the 
widest possible sense as including all localities inside a 
line from the Mull of Galloway to the Mull of Cantyre. 
The gatherings in that area can be grouped under the 
following localities :— 
(1) A couple of hauls in the middle of the North 
Channel, off Portpatrick. 
* We have also in our hands over 2,000 gatherings taken in these 
four years (1907-10) from shallower water in the Irish Sea, and these 
have been reported on fully in Trans, Biol, Soc., Liverpool, Vols, 
Xxli-xxv, 1908-11.
