BIGELOW: COAST WATER EXPLORATION OF 1913. 295 ° 
(Wright, 1907). Its absence in the Gulf Stream water and in southern 
waters in general, agrees with its distribution in European waters 
(Farran, 1910) where it seems to be of northern origin, and with 
Wheeler’s (1901) and Williams’s (1906) statements that it is most 
abundant in winter at Woods Hole and in Narragansett Bay. 
Metridia lucens, unlike M. longa, was taken regularly in the Gulf of 
Maine (eighteen out of twenty-one stations), and it likewise occurred 
at all three of the Stations outside the continental shelf (10064, 10071, 
10076). But it was found at only one Station on the continental 
shelf, south or west of Cape Cod, (10083) where the haul yielded twenty 
specimens. And we did not find it on George’s Bank or Nantucket 
Shoals. Metridia lucens was not abundant anywhere; in fact so far 
as known it never swarms in the Gulf of Maine as it does in European 
waters. It was not taken in any surface haul, the shallowest captures 
being 15-0 fathoms off Cape Ann (Station 10104), and 8-0 fathoms 
oft Long Island (Station 10083). And its invariable absence from the 
surface in our waters is evidence that it was not at home in the high 
temperatures and low salinities of the surface, because it has a well- 
marked habit of coming to the surface at night in other regions (Farran, 
1/1910). The lowest salinity in which its presence can be established 
|was about 32.4%p (Station 10104), with a maximum of at least 35.00%o 
\(Station 10071). In the Gulf of Maine most of the specimens were 
living in water of 32.67%o to 33.7%po. The limits to the temperature 
jrange of our captures were about 42° to about 50°. Metridza lucens 
has usually been called a northern species (Cleve, 1900). But Farran’s 
(1910) tabulations of the data of the International Committee seem 
to show that it really belongs to the oceanic waters of the North Atlan- 
‘ic; and that it is carried to the coasts of Iceland and to the northern 
part of the North Sea by the Atlantic Current; an explanation which 
ae fairly well with its occurrence in our waters. 
Anomalocera pattersont was taken at most of the stations in the 
—oulf of Maine, which supports my suggestion (1914a) that it is more 
( niversal in the Gulf than the records of 1912 would indicate; at five 
Spealities on the shelf south of New York (Stations 10070, 10077, 
0080, 10081 and off Hog Island) and at one of the off shore Stations 
10071); while Wheeler (1900) records it as abundant in the Gulf 
_tream south of Woods Hole. Most of the records are from the 
_arface; only one from a haul as deep as forty fathoms; and of course 
eh one specimen may have been caught at or near the surface; and 
is may also be true of the few specimens yielded by hauls from 
Wenty, twenty-five, and thirty fathoms in the Gulf of Maine. Its
