234 REPORT—1857. , 
dredging operations, owing to the strong current of the tides and the eddies 
formed by the sunken rocks. After several unsuccessful attempts to reach 
this region by Mr. Getty and Mr. Hyndman, the latter was at length, in 
1856, enabled to accomplish his object through the kind assistance of Captain 
Hoskyn, R.N., then engaged in completing the Survey, and who brought to 
the task the experience gained under the late Captain Graves, R.N., while 
dredging in the /Egean. A few hauls of the dredge produced Terebratula caput 
serpentis and Propilidium ancyloide alive, besides some rare Crustacea and 
Zoophytes. In 1857 a steamer was engaged, and a day spent in further 
explorations, the result of which is now given; but it is evident that further 
investigation in this locality is desirable and likely to repay the labour.
