te» throw out a dredge and very often success would crown our endeavours and the dredge 

 would bring up Lithothamnia. We kept a small, strong dredge for this work, for the chances 

 of losing our net and even the whole dredge were often great. The Lithothamnia appeared to 

 thrive best in from 10 — ^o m. but we as often fouiul them on the reefs near to or below 

 low-water mark, though seldom in great quantities; and again several little bits, too small for 

 determination or harren, came up at various times with the lead from a depth of 75, 83, 

 04 and 120 m.

 sank very low and we could observe that the whole reef, which stretched from the shore out 

 into the sea, consisted chiefly of Lithothamnion erubescens f. Haingsisiana. It was remarkable 

 that the branching knolls remained quite dry during several hours of the day, exposed to the 

 : tropical sun and that this seemed not to injure them. This shows clearly that at 

 some species of this genus do not fear the rays of the sun, as others appear to do in 

 the Gulf of Naples. Along the coast of arctic Norway species growing in shallow water, always
