in the colder region of the Sound. Both of these are predominantly northern species, 
as will be seen by reference to the table on page 135, giving the ranges of some of the Jocal 
amphipods. It must be added, however, that the first species is taken throughout the 
year in the surface tow at Woods Hole and has been collected along shore at various local 
points even in midsummer. In the case of two other species, Byblis serrata and Haus- 
iorius arenarius, there appears to be likewise to some extent a preference for the western 
extremity of Vineyard Sound. Neither of these, so far as known, are predominantly 
northern species, and it is likely that the character of the bottom is the determining 
factor in their distribution, particularly since Haustorius is known to be abundant on 
sand flats nearshore. Its preference for the western portions of the Sound is thus com- 
parable with that of the lady crab, Ovalipes ocellatus. A few species, on the other hand, 
appear from our rather meager records to occur predominantly in the warmer waters 
of the region. Such are Lysianopsis alba, Batea secunda, and Autonoé smithi. All of 
these have been recorded only for the immediate neighborhood of Woods Hole, and 
their general distribution is unknown. Little stress is to be laid upon any of these 
cases, however, especially since a number of other species which here reach their north- 
ern or their southern limit are distributed locally without any apparent reference to 
temperature. 
Amphithoé rubricata alone, among those species whose distributions have been 
plotted with any degree of completeness, seems to be restricted to the littoral and 
adlittoral zones. It is recorded chiefly from the inshore stations dredged by the Pha- 
larope and Blue Wing, and the comparatively few Fish Hawk stations at which it was 
taken are all in the neighborhood of land. 
The following amphipods were recorded during the Survey dredging, those taken 
at 10 or more stations being designated as usual by an asterisk:
