78 Dr. J. Hector on new Species of 



day for nearly a fortnight ; and, unlesa where here and there 

 weeds and stones afforded a shelter, these extensive sands yielded 

 no other sessile-eyed Crustaceans I'xcept Bathjporeia, Eurydice 

 pxdchra, and one single small specimen oi Sulcator. This soli- 

 tary specimen we took within the first five minutes, and expected 

 accordingly to meet with the same abundance of the species 

 as in Wales, but, with the most eager and anxious search, 

 during all the rest of the time could never find another in the 

 southern locality. Batln/poreia pilosa, on the other hand, 

 could have been taken in thousands. Its presence beneath 

 the sand is betrayed by a small furrow, sometimes short and 

 nearly straight, ending in a little pit, at others twisting and 

 meandering about and occasionally zigzagged. The mothers 

 with young look as if their bodies were tinted with a delicate 

 blue ; but this is due partly to a double stripe upon each 

 ovum, tlic colouring of Avhich is seen through the pellucid 

 sides of the parent, and partly perhaps to the contents of the 

 alimentary canal. 



In the sands at Paignton, near Torquay, I have taken in 

 close proximity to one another the sand-furrowers Sulcator 

 arenarius^ Kroyera arenaria, Bathyporeia pilosa^ and Eurydice 

 pulchra.
