Horizontal. — This species belongs to the subarctic and arctic regions. Along our 

 coast it is typical of the cold coastal water and is found over practically the whole of 

 the continental shelf. Its distribution in May-June is shown in fig. 8. Of the entire area 

 covered, it was absent at only three places ; western part of Northumberland straits 

 (Princess station 4), north of Anitcosti island (Princess stations 12 to 14) and out in

 (Corresponded closely with the deeper parts of the coast water, the shallow southern 

 part of the gulf an dthe shallow banks elsewhere showing only a few or small indi- 

 viduals. Its great abundance at the mouth of the Laurentian channel and off Banque- 

 leau at Acadia stations 12, 13, 26, 27, and 28 would indicate the presence there of a 

 large amount of cold coastal water. At the remainder of the stations off the con- 

 tinental shelf, it was present in small numbers or altogether absent.
