and west, from Cape Cod to German Bank; the stations of capture 
being so located that it can not be said to have been absent from any 
considerable part of the Gulf. And it was even found in water as 
barren of plankton as the Grand Manan Channel (Station 10,035) 
and Eastport Harbor (Loc. cit., p. 104). Few animals, except the 
copepod Calanus, were more consistent in their occurrence than 7, 
inermis. It was most abundant north of Cape Ann in early July 
(Station 10,011), and on German Bank in August (Station 10,030); 
with minor centres of abundance off Penobscot Bay in August (Sta-. 
tion 10,038) and in the northeast corner of the gulf (Station 10,036). 
Meganyctiphanes norvegica was taken at nearly as many localities 
as T’. inermis (12, as against 14); and its distribution over the Gulf 
was practically the same, except that we did not find it so regularly. 
However, its occurrences are too uniformly distributed to suggest any 
important local restriction further than that it, like 7. wnermis, was 
apparently not living in Massachusetts Bay. Meganyctiphanes was 
most abundant on German Bank (Station 10,029) and in Eastport 
Harbor, where it swarmed on the surface (Loc. cit., p. 104). Elsewhere 
it was represented by a few specimens. 
Thysanoessa longicaudata was taken less often than either of the 
preceding species, 7. ¢., at six stations (10,019, 10,027, 10,028, 10,032, 
10,036, 10,048), thus being widely distributed over the shore parts of 
the Gulf, from Cape Cod to German Bank. But it was absent, so- 
far as our hauls show, from the water close to the coast, in striking 
contrast to the abundance of Meganyctiphanes and Thysanoessa 
inermis near land. The only place where we found it in numbers was: 
in the centre of the Gulf (Station 10,027), far from land. Elsewhere 
it was represented by occasional specimens only. 
Thysanoessa gregaria was taken at the same number of stations. 
(10,019, 10,023, 10,027, 10,032, 10,043, 10,049), and usually in the haul 
with 7. longicaudata, the only station where the former was found and 
not the latter being on Platt’s Bank (Station 10,023). But it was 
most numerous near Mt. Desert Rock (Station 10,032) instead of fur- 
ther off shore. In the other hauls there were only a few specimens. 
Nematoscelis megalops occurred in only one haul, off Mt. Desert 
rock (Station 10,032 surface, a single specimen). 
When work was resumed in autumn, off Cape Ann, schizopods were 
wholly absent, though the plankton was decidedly rich otherwise 
(p. 403). And the only euphausiid taken all winter was a single 
specimen of T'hysanoessa longicaudata off Cape Ann, December 23. 
But, as pointed out above (p. 408) swarms of euphausiids appeared
