GastTRopopa—Continued. TUNICATA: 
Lacuna puteola (39). Amaroucium pellucidum (25). 
Crepidula fornicata (55). Amaroucium pellucidum constellatum (23). 
Crepidula plana (50). Didemnum lutarium (24). 
Polynices heros (27). PISCES: 
Polynices triseriata (35). Myoxocephalus zneus (22). 
The number of species here comprised is very close to those in the two lists imimedi- 
ately preceding it. Of the 54 species here present, 38 (70 per cent) were contained in the 
list for the Fish Hawk stations of Vineyard Sound, 16 being wanting from the latter. 
Conversely, the Fish Hawk list contained 13 species which do not appear in that for the 
Phalarope. It does not follow, by any means, that a species which is limited to one or 
the other of these lists is actually restricted as to depth or proximity to shore. Indeed, 
most of them appear with considerable frequency in the dredgings of both vessels. Of 
the 16 species which are confined to the Phalarope list, only 3 show a marked restriction 
to the vicinity of the shore line. These are Amphithoé rubricata, Lacuna puteola, and 
Littorina litorea. ‘The last named, as is well known, is strictly littoral (1. e., intertidal) 
in its habitat. The dredging records refer exclusively to shells, most or all of which were 
doubtless transported from the shore by hermit crabs. On the other hand, of the 13 
species restricted to the Fish Hawk list, only 6 give any evidence of a preference for 
deeper waters than those dredged by the Phalarope and Blue Wing. These are Euden- 
drium ramosum, Cellepora americana, Asterias vulgaris, Modiolus modtolus, Venericardia 
borealis, and Astarte castanea. In the case of the last two species named, the avoidance 
of the inshore waters is quite obvious. Of the others this can not be stated as confidently.
