The hauls combined under the present heading vary somewhat 

 individually, but the prevailing features are the same, and indicate 

 a predominant sand fauna mixed with a considerable number of species 

 characteristic of the gravel grounds which lie immediately to the north, 

 especially Ground XIV. 



Bottom-deposit. This is probably fine sand over the whole ground, 

 though the more northerly hauls may have been taken partly on gravel 

 and partly on fine sand. Gravel was noted at the time in haul 76.
