15. Metridia longa and lucens.- — The mutual relations of these two species in their 

 distribution may be gathered from the tables. The former species ranges far and wide 

 in the Gulf of St. Lawrence having been taken in deep water in the Gaspe channel at 

 No. 33 station 23. In the Bay of Islands at No. 33 station 57 a typical Metridia longa 

 plankton was obtained. On the other hand Metridia lucens does not seem to penetrate 

 so deeply into the gulf of St. Lawrence being only recorded at two stations, namely, 

 at No. 33 station 69 (3 per cent) and Princess station 45 (5 per cent). It was also 

 taken by Dr. Huntsman at Prince stations 1, 2, and 3. Its distribution at represen- 

 tative stations is shown on the map (fig. 27). It was generally taken in vertical hauls, 

 rarely at or near the surface. It was taken regularly by the Grampus in the gulf of 

 Maine, while M. longa only occurred sparsely. Bigelow states that M. longa was not 

 found in the gulf of Maine in the 1912 cruise, and its discovery in the 1913 cruise was 

 the first record for American waters.
