DESCRIPTION OF THE EXPEDITION. 163 
Apprnpix A.—LIST OF THE DREDGING-STATIONS. 
Tn addition to the dredgings mentioned below, there were a considerable number of 
hauls in different localities between Mauritius and the Seychelles of which we kept 
no record, as no specimens were secured, and they gave no information as to the nature 
of the bottom, &c. The Chagos dredgings are not recorded in our list. There were 
altogether seventeen hauls outside Salomon Atoll. They gave a good idea of the nature 
of the bottom around it, though few specimens were secured. In addition, a considerable 
number of dredgings were put down in the lagoons of Salomon, Diego Garcia, and 
Egmont Atolls in connection with their formation. Their precise positions within these 
lagoons we have not deemed it necessary to record. The positions of the dredgings 
between Mauritius and the Seychelles are all marked on the maps of the different banks 
visited and embodied in the “Summary” of our cruise. References are given under 
each locality. 
The dredges and trawls employed have already been described (p. 17). They 
consisted of rectangular dredges with swords of 5, 4, 3, and 2 feet, triangular dredges 
with swords of 4, 3°5, and 2°5 feet, and double-sided trawls of 9, 6, and 4°5 feet. 
The positions of the dredgings will be seen by reference to the text of Part IT. of this 
Report, figs. 25, 28, 31, 39, 41, 44, and 46.
