(7) TARPAULIN COVE. 
Tarpaulin Cove proved interesting in several respects. The westerly side (station 
17) has a bottom of sand and gravel in 214 to 4 fathoms, and there was an abundance 
of Desmarestia viridis and Antithamnion cruciatum, and in small quantities Cladophora 
gracilis, Agardhiella tenera, Antithamnion plumula, Callithamnion Baileyi, and Grin- 
nellia americana; the dredge brought up large quantities of Zostera. The upper end 
of the cove (station 18) in 214 fathoms has a bottom of mud and gravel supporting 
extensive beds of Zostera, and an abundance of Polysiphonia nigrescens. A line dredged 
across the entfance of the cove (station 19) showed a muddy bottom with occasional 
plants of Polysiphonia nigrescens. WHauls made at the eftrance nearest the lighthouse, 
July 18, 1903 (Phalarope), showed the presence of much Seirospora Griffithsiana and 
small quantities of Desmarestia viridis, Laminaria Agardhi, Agardhiella tenera, Calli- 
thamnion Baileyi, Ceramium fastigiatum, Ceramium rubrum, Champia parvula, and 
Grinnellia americana. 
(8) VINEYARD HAVEN. 
Station 69 off West Chop, at the entrance to Vineyard Haven, was very rich in 
algee and especially interesting as a locality for Rhadinocladia Farlow. The bottom 
was sand and stones in 3% to 7 fathoms and supported extensive growths of Zostera. 
There was much of the following: 
Ralfsia clavata. Hildenbrandia prototypus. 
Rhadinocladia Farlowii (on Zostera). Lomentaria uncinata. 
Sphacelaria radicans. Melobesia farinosa. 
Agardhiella tenera. Melobesia Lejolisii. 
Antithamnion cruciatum. Phyllophora Brodizi. 
Callithamnion roseum. Phyllophora membranifolia. 
Ceramium tenuissimum. Spermothamnion Tumeri. 
In small quantitles were: 
Cladostephus vertillatus. Callithamnion corymbosum. 
Desmotrichum undulatum. Dasya elegans. 
Ectocarpus confervoides. Lithothamnion polymorphum. 
Sphacelaria cirrhosa. Polyides rotundus. 
Ahnfeldtia plicata. Spyridia filamentosa. 
Vineyard Haven proper (stations 70, 71, 72, and 7762) presented little variety in its 
algal life but considerable quantities of certain species. Station 70 in 4 fathoms, with a 
bottom of stones and Crepidula shells, gave much Agardhiella tenera, Champia parvula, 
Grinnellia americana, and Lomentaria uncinata; in small quantities were Rhadinocladia 
Farlowii (on Zostera), Antithamnion cruciatum, Callithamnion corymbosum, Ceramium 
strictum, Ceramium tenuissimum, Hildenbrandia prototypus, Lithothammon polymor- 
phum, and Melobesia Lejolisii. Station 71, with a bottom of clam and pecten shells, 
stones, and mud, in 314 fathoms, gave an abundance of Sphacelaria radicans, Agardh- 
iella tenera, Champia parvula, Grinnellia americana, Lomentaria uncinata, and Phyllo- 
phora Brodiei. Station 72, stones and mud, in 3 to 4 fathoms, showed large quantities 
of Calothrix confervicola, Sphacelaria cirrhosa, Agardhiella tenera, Champia parvula, 
Lomentaria uncinata, Melobesia Lejolisti, and Spermothamnion Turneri, and a few plants
