II. 5. ANIMALS INHABITING THE ROCKY BOTTOMS OF THE BAYS AND 



SOUNDS. 



In this region the proportion of rocky bottom is relatively quite 

 small, and mostly to be found only in quite shallow water. Therefore the 

 animal life is very similar to that of the rocky shores and tide-pools, 

 near low- water mark. 



In Vineyard Sound and vicinity the rocky bottoms examined were 

 chiefly at the following localities, as indicated on the accompanying 

 chart, viz.: 1st. An area south of Parker s Point and occupying a part 

 of the bottom of the passage between Parker s Point and Nonamesset 

 Island, on both sides of the channel, and extending somewhat south of 

 a line drawn from Nobska Point to the southeastern end of Nonaines- 

 set Island. The dredgings made in this area are, 9, , Z&amp;gt;, c, d ; 2, a, &/ 

 3, a, &, c ; 4, , b ; 5, c, rf, e ; 8, a, 1) ; 18, a, &. 2d. An area south 

 and southwest of Nobska Point ; dredgings, 21, &, e ; 22, a ; and 

 others not recorded were made on this patch. 3d. In the Wood s Hole 

 passage, between the north end of Nonamesset Island and the opposite 

 shores, there are numerous rocky patches, and the tides flow with great 

 force 5 dredgiugs, 14, a, Z&amp;gt;, c, rf, e, /, g; 16, a, I ; 17, c, d, e; 15, , ft; 

 and many others were made on this bottom. 4th. A small area between 

 Uncatena Island and Long Neck; dredgings, 11, e, /, and 71, c, were 

 on this patch. 5th. A small area, south of the Wepecket Islands, where 

 the dredging, 73, d, was made. 6th. A region of rocks and sand off 

 West Chop, north of Martha s Vineyard ; in the dredgings made here, 

 37, c, t7, e, some very fine hydroids and ascidians were obtained. 7th. 

 In Quick s Hole, the passage between Nashawena and Pasque Islands, 

 a rocky bottom, with abundant ascidians, hydroids, and sponges, was 

 found, where dredgings 77, a and c, were made. 



In addition to these localities numerous dredgings were made on 

 rocky bottoms off Gay Head and Devil s Bridge, and also between 

 Martha s Vineyard and No Man s Land, but these properly belong to the 

 cold outer region. 



In the vicinity of New Haven, rocky bottoms, generally of small 

 extent, are found off the light-house, and off South End and Brauford 

 Point, also among the Thimble Islands. All these localities have 

 been examined by me in numerous dredging excursions made during 

 the past eight years. Nevertheless the fauna of the rocky bottoms of
