(5) QUICKS HOLE. 



Quicks Hole does not have so luxuriant a vegetation as Robinsons Hole, probably 

 because the bottom is not so rocky. On the easterly side (station 27), along the west 

 end of Pasque, in 4 to 5 fathoms over a rocky bottom, there was a rich growth of 

 Desmarestia aculeata, Laminaria Aqardhii var. viitata, Callithamnion Baileyi, Phyllophora 

 BroduBi, Rhodymenia palmata, and a few plants were found of Desmarestia viridis and 

 Cysioclonium purpurascens var. cirrhosum. The westerly side (station 28 and 29) has 

 a sandy bottom in 3 to 5 fathoms, with quite a different vegetation. There were found 

 in abundance Chorda filicm (station 29), Desmarestia aculeata (station 29), Desmotrichum 

 undulaium (station 29, on Zostera), Ectocarpus silicidosus (station 29, on Zostera), 

 Melobesia Lejolisii (station 29, on Zostera), and Spermothamnion Turncri. The following 

 were found in small quantities : 



Chordaria flageUiformis, 29. 

 Laminaria Agardhii, 28. 

 Leathesia difformis, 29. 

 Agardhiella tenera, 28. 

 Chondrus crispus, 29. 

 Corallina officinalis, 29. 



Cystoclonium purpurascens, 29. 

 Hildenbrandia prototypus, 28. 

 Lithothamnion polymorphum, 2 

 Polysiphonia elongata, 29. 

 Polysiphonia fibrillosa, 29. 

 Rhodomela subfusca, 29. 



(6) MENEMSHA BIGHT. 



A special trip to Menemsha Bight was made on July 17, 1905, in the Genevieve of 

 the Marine Biological Laboratory. Three hauls were taken, (i) at the east end of 

 Menemsha Bight just outside of the fish traps, bottom sandy in 6>^ fathoms; (2) in 

 the middle region between the fish traps, bottom sandy mud in 5% fathoms; and (3) 

 about three-fourths of a mile offshore at the west end of Menemsha Bight, bottom 

 sandy in 8>2 fathoms. The following species were recorded: 



Chaetomorpha Linum, 3, few. 

 Desmarestia viridis, 2, many; i and 3, 

 Laminaria Agardhii, i, 2 and 3, few. 

 Ralfsia clavata, 3, few. 

 Sargassum Filipcndula, i, few. 

 Agardhiella tenera, i, many. 

 Antithamnion cruciatum, i, few. 

 Antithamnion plumula, i and 2, few. 

 Callithamnion roseum, 2, few. 

 Ceramium rubrum, 2, few. 



few. 



Champia parvula, 3, few. 



Cystoclonium purpurascensvar. cirrhosum, 2, many. 



Hildenbrandia prototypus, i and 3, few. 



Phyllophora Brodiaei, 2, few. 



Polysiphonia atrorubescens, 2, few. 



Polysiphonia elongata, 2 and 3, many. 



Polysiphonia fibrillosa, 2, few. 



Polysiphonia nigrescens, i, 2 and 3, very abundant. 



Seirospora Griffithsiana, i, 2 and 3, few. 



Spyridia filamentosa, i, few. 



The most remarkable feature of this locality was the great quantity of Polysiphonia 

 nigrescens. The flora of these sheltered waters was clearly representative of the warm- 

 water sublittoral formation, a fact of some interest considering its proximity to Gay 

 Head. 



An examination in the Blue Wing of the shallow waters of Menemsha Bight, off 

 Lobstervdlle, on August 9, 1904, showed a bottom of sandy mud in 3 fathoms. Zostera 

 was plentiful in spots and seems to be establishing itself in this region; there was verv 

 little present four or five years previous (Vinal Edwards). There were great quanti- 

 ties of Ectocarpus siliculosus as well as Melobesia Lejolisii covering the Zostera, and a 

 few plants of the following were found: Agardhiella tenera, Chondrus crispus, and 

 Cystoclonium purpurascens var. cirrhosum.
