Marine Dredgings and other Natural History Materials. 167 
referred to, Mr Binnie says, “ Amongst the material that 
belonged to the late Mr George Brook there is a set of 
dredgings from the West Coast of Scotland, collected by him 
while cruising in his father’s steam yacht ‘Dotterel.’ In 
the collection there are a good many Crustacea, some other 
invertebrates, and a few fishes. We are most anxious 
that the material should be worked up and not wasted, so 
that Mr Brook may get some credit, even though it be 
posthumous.” 
The collection soon afterwards was handed over to me, 
and, as Mr Binnie anticipated, the examination of it has. 
proved to be interesting. A record of the results of the 
examination is embodied in the following report, which I 
now desire to submit to the Royal Physical Society of 
Edinburgh. 
GENERAL DESCRIPTION OF THE COLLECTION. 
Before proceeding to give a record of the various organisms 
contained in the collection, the following brief description of 
the collection itself may be of interest. The material was 
collected by means of the beam-trawl, the dredge, and the 
tow-net; tow-net gatherings, however, formed but a small 
part of the collection. The material forming the collection 
was contained in upwards of two hundred bottles and tubes 
of various kinds, but they were chiefly of small size. It 
was collected for the most part during the months of July, 
August, and September 1887, but it also included one or 
two small gatherings made in 1886 and in 1888. Moreover, 
it was collected at various localities,—as, for example, in 
Loch Fyne; in the vicinity of the Island of Mull, and in 
Loch Linnhe; off Ardnamurchan; in the Gairloch; in the 
vicinity of the Island of Skye; and at one or two places in 
the Outer Hebrides. The material was also collected at 
various depths, from close inshore down to 100 fathoms. 
The contents of a few of the bottles were somewhat 
decomposed, owing to the partial evaporation of the spirit,
