alveolata, Littorina littorea, Doris pilosa, Doris proxima, 
Chiton cinereus, and numerous very fine specimens of 
Bugula turbinata. 
During a considerable part of April, Mr. Harvey Gibson, 
Dr. Hanitsch and Mr. F. Villy worked at the station. Mr. 
Gibson confined his attention to the Rhodophycee, and 
he informs me that since his last report, published in the 
‘‘Hauna,”’ vol. i1., he has found and identified seventeen 
species of Algz, mainly parasitic forms, not previously 
known in the district. Dr. Hanitsch has continued his 
researches on the Sponges during the year, and reports 
six species additional to those recorded in the ‘“‘ Fauna.” 
Of these three are new to science and will be figured and 
described in detail under the names, Azinella mammullata, 
n. sp., Leucaltis wmpressa, n. sp., and Halisarca rubra, 
n. sp., In the next report on Sponges by Dr. Hanitsch. 
The last species was obtained by dredging in deep water 
during the “‘Spindrift”’ expedition of July 20th, while the 
two first were collected on the rocks at Puffin Island in 
April.

The Salvage Association have again this year afforded 
us the opportunity of making some investigations which 
could certainly not have been carried on without the use 
of the s.s. ‘‘Hyzna.’’ The old gunboat left the Mersey 
on Thursday morning, the 18th of April, on her fifth 
scientific cruise, and was absent five days. ‘The proposed 
course was to cross to Port Erin, at the south end of the 
Isle of Man, and then dredge southwards to Holyhead, 
through the deepest water to be found in this district ; 
then to work along the coast of Anglesey to Puffin Island, 
and from that back to Liverpool. Besides the ordinary 
dredging and tow-netting operations, it was hoped that
