CAXADIAX FISHERIES EX/'EDITIOX, 191^,-15 189 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. ©-.© ySy ®®© ® (^^ (5) @ w Fig. 9.—Distribution of Euihirelhi The numbers indicate percentage of cojjepod Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Canada.
