WORK OR THE ‘INVESTIGATOR.’

occupied the Marine Survey for that and the next following 
season, but in 1901-02, for the first time in her history, the 
‘Investigator’ visited the Persian Gulf, and twenty trawls 
were made at stations ranging from the Arabian Sea, through 
the Gulf of Oman and the Straits of Ormuz to the Persian 
Gulf. Unfortunately McArdle did not live to investigate 
the results of these operations, for he died of cholera on 
October 11th, 1902, while officiating Superintendent of the 
Indian Museum, in Calcutta. 
At the end of season 1900-01 it had become necessary to 
submit a new programme of work. Most of the ports and a 
good deal of the coast-line of India and Burma had been 
surve 3 md, and it was felt that the time was then ripe, when 
the survey of the coasts could be taken in hand systemati¬ 
cally. The programme put forward comprised the survey of 
the Tenasserim coast, from Moulmein to the southward, and 
after that, the Arrakan coast, to the south of Elephant Point: 
this was sanctioned, and the work duly commenced. 
In March 1903, Captain MacGilchrist was appointed to 
succeed McArdle. Owing to climatic conditions being un¬ 
favourable, the survey of the Burnia coast had to be inter¬ 
rupted and the opportunity was taken to carry out a survey 
of some of the smaller harbours and inlets in the Middle 
Andaman, and on several occasions shore-collecting on the 
various islands and reefs was carried out. During the season 
1903-04 the survey of the Burma coast was again continued, 
the areas under investigation being Akyab and Hinze Basin: 
this latter was an enclosed sheet of water having two inlets 
to the west and south. During the progress of the survey 
the ‘Investigator’ proceeded into the basin and remained 
there for some weeks, during which time MacGilchrist was able 
to make an extensive collection of the shallow-water fish and 
other organisms, but as the shore consists, for the most part, 
of mud-flats and mangrove-swamps, he found that shore¬ 
collecting was in many places impossible. 
During the following two years the areas under investiga¬ 
tion were parts of the Persian Gulf and Aden harbour and its 
approaches. In 1905 Captain R. E. Lloyd, I.M.S., was ap¬ 
pointed to succeed Captain MacGilchrist, and he was thus
