know that any marked features, as regards the distribution of 

 the species, are elicited by an examination of this collection ; but 

 the water off Tynemouth is certainly rich in the rarer forms, 

 such as Nychia cirrosa, Ophiodromiis vittatus, Sabellides octocir- 

 rata, Pista cristata, and Trichobranckus glacialis. Some of these 

 are especially characteristic of the deep water (with a muddy 

 bottom) off the western coasts of the Hebrides and the Shetland 

 Islands, and they are less frequently met with on our eastern 

 coasts. 



A specimen of Lepidonotus squamatus had forced itself when 

 alive into the tube of Protula, so that in the preserved condition 

 its appearance was very much altered.
