excreta?), which I take to mean Sahellarla alveolata; while 

 their enemies are generally said to be cod, whiting, flukes, 

 small thornbacks, weevers, and crabs (especially "white 

 crabs," Polt/hlushenslowi). Pleurohrachia ("marble blebs"), 

 which is sometimes put down as an enemy, would be very 

 unlikely to be able to injure a shrimp. 



It may be of interest perhaps to record a typical week- 

 end visit to Puffin Island in rather wintry weather. Near 

 the end of October four of us (Mr. Thompson, Mr. Gibson, 

 Mr. Leicester, and myself) arrived at the Island on a Satur-

This particular expedition to the Island was made

 directions for making collections and taking observations 

 during the winter. Certainly the biologists have never 

 before been so comfortably housed at Puffin. The ar- 

 rangements in regard to board and lodging were as 

 satisfactory as could well be in such a delightfully iso- 

 lated spot, where everything, from a sack of coals to 

 a pat of butter, has to be brought from Bangor, if not 

 further, landed when possible on the rocks or the shingle, 

 and conveyed on one's own back, or the donkey's — usually 

 the former — up a cliff, and over half a mile of island top, 

 consisting chiefly of long grass, limestone rocks, and awk- 

 wardly placed rabbit holes, before it reaches the biological 

 station. The new sleeping bunks, fixed in three tiers of
