132 BULLETIN OF THE BUREAU OF FISHERIES. 
large collection of specimens taken by Mr. Edwards with the tow net, or gathered by the 
Survey parties during the shore collecting, has been identified for us by Dr. B. W. 
Kunkel. A few of the readily recognizable forms (e. g., Unciola wrrorata) were frequently 
listed in the field. Unfortunately during the first season all the Caprellide were recorded 
by the collectors as ‘‘Caprella geometrica.”” Since some other members of this genus 
have been recorded from the region, and particularly since the allied Eginella longicornis 
is found with great frequency, such records are, of course, equivocal, and they have been 
changed to ‘‘Caprellide sp.” Later dredgings have, however, resulted in differentiating 
to some degree the distributions of these species, but not sufficiently to warrant 
our plotting out a separate chart for each. We have consequently prepared a single 
chart showing their combined distribution. 
On the average 1.6 species of amphipods are recorded for each of the Survey dredge 
hauls. The species found to have the most general distribution was Unciola wrrorata, 
which was taken at 115 of the regular dredging stations. No other member was 
encountered at as many as one-fourth the entire number of stations. 
The most salient fact respecting the distribution of the bottom-dwelling amphipods 
in local waters is the paucity of species in Buzzards Bay as compared with Vineyard 
Sound. In fact, of the 19 species for which distribution charts have been plotted, only 
2 are shown to be of greater abundance in the Bay, while not more than 2 others seem 
to be present in about equal numbers in the two bodies of water. We may for con- 
venience group the species as follows with reference to their comparative abundance 
in one or the other body of water. 
Species wholly or chiefly restricted to Vineyard Sound.
