9. Euchirdla rostrata. — Several species of Euchirella occurred in the vicinity of 

 the Gulf Stream but the most widely distributed was this one. It has a distinctive 

 appearance with its portly crimson-tinted forebody and short urosoine. It was present 

 in varying quantity at twenty-four of the Acadia stations but never in the surface 

 hauls. At stations 85-87 which traversed the Laurentian channel between St. Pierre 

 and Mrsaine banks, its mode of occurrence is significant in view of what has been said 

 before. At each of these stations a vertical haul was taken from 30 fathoms to the 

 surface, and another from 150 or 160 fathoms to the surface. At station 85, Euchirella 

 rostrata occurred in both of the vertical hauls, two per cent from 30-0 fathoms, five per 

 cent from 150-0 fathoms; at stations 86 and 87 it was present only in the deeper hauls. 

 Its distribution within our area is shown on may (fig. 9). At station 54, where it appeasr 

 with the high plurality of 43 per cent, it should be mentioned that the plankton here 

 was very scanty, the vertical haul (150-0 fathoms) including only about 140 copepods 

 in all. Other species of Euchirella were taken as indicated on table XL
